栀子护理

在油绿叶香乳白色的栀子植物白花使它成为不可抗拒的植物生长。 通常在开花或花蕾,醉人的芬芳诱惑卖给我们,使之成为必须有厂,但可挑剔的栀子花和挑战,在室内生长。 事实上,一些视为一次性植物,并开花后丢弃它。

栀子花花

栀子 (栀子)需要宽松排水良好,酸性(ph4.5 - 6.2)土壤,阳光明亮的室内6-8小时和灿烂的阴影(早晨的太阳时,在夏季室外)。 它喜欢高湿度和潮湿,但不潮湿的土壤。 饲料用二分之一的实力酸肥料每2-4周从3月至10月。
冬季保健 :提供一个凉爽明亮的位置,湿度和防止加热通风口了。 不施肥和水少允许顶端1-2英寸再次干燥,然后浇水。

开花:栀子花芽的形成需要在一个62-63 F和高湿度,温度均匀。 为提高水卵石盘湿度发生装置或接近加湿器。 当芽的形成,提供了一致的(58 - 60F章)和温暖的日子(70 - 75F)凉爽的夜晚。 阿10-15度的温度差,需要防止关闭(芽爆炸)去掉了芽。 开业花应该持续3-8天,可以轻易地在触及瘀伤。

修剪后,开花周期已经结束,或当工厂正积极增长,需要修剪。 不要在冬季修剪。
繁殖:以在早春3-4英寸的半木质小费从非切削开花拍摄。 删除下部叶片,在生根激素和潮湿的泥炭中插入切割,蛭石混合下跌。 它应扎根于4-6周。

疑难解答
栀子花吸引昆虫数量:蚜虫,介壳虫错误,规模,红蜘蛛螨和蓟马。 他们还容易受到根腐病,芽下降,黄叶。

    开花的要求
    您好,刚刚找到您的网站和爱。 我在佛罗里达州的栀子植物 ,但它不是开花,虽然它是郁郁葱葱的绿色和健康。 我妈妈已经与麻省理工肾综合征出血热同样的问题。 怎么做才能促进我们原本健康的不起眼的植物开花?

    栀子盛开通常每年一次,在夏季的春天。 他们需要几个条件设置花芽。 全太阳4-6小时,湿度大,夜间降温(58-60)和温暖的日子(70-75)。 花芽在温度62-63 degreesF一形式,届时该工厂应具有较高的湿度,甚至水分。 如果允许土壤干燥或太湿,它将放弃芽。 气温波动,如过暖,冷草案还将导致芽下降。 他们有点挑剔。 饲料与酸肥三月(Miracid)至10月的工厂时,该厂正在积极发展。 如果在夏季室外保持在局部阴影了。 开花后剪枝(春季)后来修剪植物可以消除明年的花。 佛罗里达州的气候应该是非常适合的,而大众栀子将需要更多的努力以保持湿度它需要。

      生长点
      回切,在天气寒冷时,开始饲料的Muracid捏到每加仑的水一周。 做4个月,然后不要再饲料为8个月,只是水。 在喂食的时候会成立萌芽和壮大。 在非喂食的时候会休息。 栀子花需要休息,以保持健康和生产开花。

    冷害
    我有一个问题没有发表评论。 我种在我的窗台上正接受3 栀子灌木 我认为,他们几乎死去由于严寒的天气,我们有这个冬天。 是否有办法能救我的栀子的? 我还没有看到它们开花。

    等着看多少冷害你确实有。 如果您已经干枯树枝,看上去就像是没有生命迹象,修剪并检查新的增长时,天气回暖。 最好是等到春天修剪的冷害。 他们不喜欢与排水良好,酸性土壤明亮,温暖湿润的条件。 如果真的有生命迹象(新叶)水和施肥(muracid在春季),以鼓励增长。 栀子花是霜冻招标等品种在不同地区9-11 hardy中。

    我住在希腊和刚刚买了第一栀子 多久我想水,应该把我给肥呢?

    如果植物是在室内容器,使您的栀子花稍微潮湿,但不湿(不要让水站),不要让它枯萎。 您可能需要检查每天浇水,尤其是在天气炎热。 水当土壤干燥顶部英寸。 您可能需要较少的水在冷却器冬季。 还提供了大量的湿度。 饲料的酸平衡施肥(Muracid)有一次,从3月份至10时,该厂正在积极发展。 按照制造商的指示。

    黄叶

    我有一个黄色树叶的问题。 我应该怎么做,以帮助工厂?

    泛黄您的栀子花叶子可能是水分供应过量的迹象,underwatering,过高的pH值(6.5以上)或铁缺乏症。 缺铁黄化(interveinal叶减轻)可以由一个高pH值引起的。 饲料厂的1 / 2的力量酸肥料 ,或者向螯合铁的土壤和叶片喷雾。 您也可以使用茶水每月一次,以维持低pH值(酸性土壤)。

    我与18个白宝石的栀子花和18月种植在今年英语boxwoods正式喷泉花园。 在花园里非常充分地绿油油的树叶和整个夏季开花。 此时的外叶仍在增长,但在健康的绿色灌木丛中有深厚的叶子变黄,但他们不脱落。 的任何问题或建议,或补救这是正常的吗?

    您好贾尼斯
    有些发黄的叶子也可以是正常的,如果他们要低,年纪较大的树叶或对工厂的内部叶片。 如果新的叶子变黄您的栀子花,那么这可能会导致营养素缺乏症(萎黄)。 还要检查,如规模和蜘蛛虫害密切螨

    我的植物叶片有光泽,湿带有粘性残留植物似乎是健康的,我无法看到很多昆虫。 ihave了我的夹竹桃米利错误,并成功地治疗马拉硫磷。我应该使用不同的东西,我栀子

    如果您有米利错误你会看到它。 另一种昆虫的袭击栀子和生产残留物,是一个棘手的规模可能不容易发现。 仔细看看的茎和可刮掉,然后用手指把树叶undersides颠簸。 一个放大镜确实有帮助。 他们留下一个明确的叶面粘性残留物。 这种治疗将取决于你的工厂在哪里增长(室内或室外)。 您可以使用马拉硫磷处理的规模,如果在标签上列出。 它将杀死昆虫履带阶段而不是在shell阶段。 您可能需要几个应用程序。 在室内不要使用喷雾喷涂时的预防措施。 不要使用栀子杀虫肥皂,因为他们有一种倾向,敏感的肥皂喷造成药害(黄/棕色提示发现和焚烧。

    Repot栀子

    我有室内栀子现在2年,我不知道何时需要重新盆栽植物高大,非常健康,请告知大约有一英尺

    Repot您的栀子花的根源时,填补了锅。 您将看到在土壤表面的根源以及即将到来的底部排水孔了。 他们实际上盛开时稍微好盆栽的约束。 为了让新的蓬勃发展,成为一个货柜1英寸的春天大repot。 它可能准备在未来的大小锅。

    叶干燥冰壶

    一个朋友给了我一个什么是两条一个盆栽栀子看起来移植室内植物 它是健康的,在过去4个月看,但最近的植物的叶子一开始干燥卷曲 可以的植物之一是根的约束,我应该把它和重植分开?

    在干燥和叶片卷曲可以是不均匀的压力就浇水或低湿度造成的根源结果。 栀子花不喜欢其根源不安。 分离的两个工厂将导致大量的创伤已经征税的根系统,因此我不建议分割。 如果您觉得是根植物的约束,在基层出现上述的土壤和走出底部的排水孔出,然后repot成1-2“大容器开始 ,把春天的增长。 栀子花花时,最好稍微壶的约束。 修剪的干茎,但不分离工厂。

  • 吉娜

    树叶落
    我有一个给了我栀子花 ,它是做不太好,因为我是困难时期定期浇水。 所以,一旦我开始这样做了,但叶时做得非常漂亮,得到真正的绿色。 我没有改变浇水周期,但对一些所有的叶子枯萎,开始卷曲,然后... ..原因 当我去触摸的叶子,下跌了! 所有的叶子掉下来,除了在最后的一些新的增长点。 我认为这可能是锅,所以我最近repotted它 - 这是做了些,但仍然没有叶子的树枝,在刚刚结束的新的增长点。 更多新的增长已开始萌芽的自下而上的 - 但我想知道是我应该修剪过的分支,他们没有他们离开? 即使是在结束新的经济增长? 它只是看起来很赤裸裸的,没有树叶! 它没有在所有开了,因为我的圣诞礼物。 帮助?

    不均匀水分和低湿度会导致栀子脱叶和芽。修剪过任何枯枝或者是那些对他们没有离开。 既然你有新的增长,从种植基地的到来,还削减了“赤裸裸”源于这将刺激方竹笋,产生更看工厂。 提供过滤光线明亮,统一水分和湿度(卵石放在一个托盘上)和施肥的二分之一强度酸肥(每2周3月至9月)得到它去。

    栀子花是非常情绪化在开花时,他们会放弃他们的耳机,或无法打开,即使你看他们走错了路。 一个位置,如移动设备,任何温度波动冷,热,湿度低,对下浇水的变化(有需要,即使水分在开花时),而没有足够的光线都可以导致花中止或停止开放。

    我有一个室内栀子 它的新叶,芽形成。 但是,旧的叶子变黄脱落 另外还有一些正在形成一个网络(如蜘蛛 )的微小的昆虫。 如何摆脱他们? 我在新泽西州地区。 谢谢

    栀子花很容易受到叶螨像你说的是什么声音。 泛黄的叶子也可以造成营养素缺乏以及晚年。 春天是一个好时机,开始喂以“酸”的肥料(Miracid)您的工厂。 按照制造商的指示。 额外的茶叶水,每2周将有助于保持土壤酸性。

    谢谢

    栀子花是很难保持室内。 温度差是获得工厂设置芽,这就是为什么它们是在温室种植在温度可控制。 通常情况下,气温将下降足够在夜间和白天温暖,保持了芽。 他们喜怒无常,容易受到许多昆虫。 我不知道什么是灰色的错误,可能是蚜虫叶螨 我已经读到了杀虫肥皂使用可导致植物栀子的敏感性。 研究的栀子花标记除虫菊酯喷雾剂。 您的工厂正显示出紧张的迹象,将放弃其芽任何时候有一个环境的改变,高气温,湿度低,热或冷草稿,太多或没有足够的水。 小心不要水上,或让其干燥,保持土壤湿润均匀。

    您好弗朗辛
    这是一个艰难的植物种植在干燥的气候。 它不仅需要的湿度,但叶和芽的部分下滑可能是由于气温的波动和环境的变化。 任何时候,强调植物,它的反应也会通过删除其芽和叶。 让您的设备和施肥均匀湿润半强度酸肥2-3周后,开花植物完成它。 你可以喷雾雾植物,以增加湿度。

    您好伊娜

    栀子可以忍受充分的阳光,但是正如你所说,它可能会在夏天最热的时候是一个问题。 最好的你能做的就是拭目以待。 秋季天气将有助于建立工厂。 覆盖的植物有2-3木片“,以保持湿润凉爽的根源。 一定要与Azalea食物施肥一次在生长季节每月得到确保它在炎热的季节足够的水。 树提供一些灿烂的夏季遮阳将是很好。 祝你好运栀子。 希望他们成长良好。

    您好玛丽
    您可以络合铁饲料2-3次。 其中一个问题可能是冷的温度。 栀子花需要的温度为62 - 63F时,芽芽形成或将下降。 如果温度低于55F去工厂无法使用铁和叶成为褪绿(黄色)。 请确保它是一个高湿度温暖的地方,然后应用铁。 还检查昆虫,它们也可能导致树叶变黄。

    您好沙龙
    疲软的问题可能是由于不是太多水或没有足够的水。 如果土壤潮湿,栀子仍然枯萎,则可能overwatered这会导致根腐病。 要确保排水良好,盆栽植物是不溶于水的地位。 如果它是一个underwatering的情况下,工厂应该振作起来在几个小时后,浇水。

    您好克里斯蒂娜
    这是经历移植的冲击。 无需施肥现在,栀子不喜欢他们的根不安,需要适应环境,以新的环境。 让工厂干,浇水之间,以避免水分供应过量位。 由于根已被打乱,叶片萎蔫和变黄。 损坏的根源不能发送了足够的水来的树叶在阳光点击他们,令他们枯萎。 Gardenia的恢复时,将减少对植物的压力。 叶子泛黄也会发生的工厂试图减少数量叶子它需要维护。 它需要时间来恢复。

  • 蚜虫
    I have a gardenia tree , it was doing pretty well outside, since I got it inside I noticed something everyday, my latest problem was white skins on the buds & leaves was shinyy & sticky. I cut the bud & took the nursery ( the spray they gave didn't work), my second visit he told me to clean the leafs with alcohol ( and that I think killing my plant now), I still have those white skins (not like before but still some) and now most of the leafs dried & turned dark brown. 有什么建议? what can I do about white skins? and what can I do about dry brown leafs? (it doesn't turn yellow, just dark dry brown). Thank any info you can give me.

    Hi Ann
    Sounds like you have aphids. The white skins are cast skins of aphids. You don't mention what kind of sprays you used. Gardenias are sensitive to insecticidal soap. A hard spray with the hose will help elliminate most but not all. Look into pyrethrin sprays labeled for gardenia. Neem and a pyrethrum/alcohol spray are also effective. Several treatments are needed in order to be effective.

  • Ann

    Leaf drop

    I lost most of the leafs of my gardenia tree & I trimmed some ( everyday I have dry brown leaves) even green leaves are just dry, I don't know what's going on, still living for now but not much leaves left & I still have that aphids ( gonna look for pyrethrin spray). thank you, any ideas about dry leaves ( not yellow) just dry (some are dark brown or black) and some green ( but dry).

    HI Ann
    In addition to the insect problem, a gardenia will drop healthy leaves when the soil and/or air moisture is too dry (low humidity). Exposure to drafts such as heating vents and air conditioning will also cause leaves to drop. Leaves that turn dark brown/black can be caused by keeping the plant too cool ( below 50 degrees). You may need to increase the humidity indoors.

  • Ann

    Thanks for your quick respond, my gardenia tree is front of the window & next to the heating vent ( even I closed the vent) it might be to dry & too cold ( for being right front of the window). I am going to move the plant from there to another place tomorrow morning. I have one more question though, I want to buy a humidifier ( for the gardenia, for the increase the humidity), which one should I get? warm or cool moisture humidifier? 非常感谢。

    I don't know much about humidifiers, I would think the warm air one would work in the near vicinity of the plant. You can also use a pebble tray-which is a large saucer with a layer of pebbles and a layer of water just below the pebbles. Place the plant on top of the pebbles. The evaporating moisture will benefit your plant. Grouping several plant together also helps increase humidity.

  • 珍妮

    I have a gardenia bush that I planted last spring and it has grown beautifully outside. I'm concerned about it now since winter has started. I live in zone 7 and it has gotten down into the 20s some nights. I've noticed the bush has turned very brown even though I've been covering it with a sheet on the coldest nights. Will it get new growth in the spring and will it bloom? Do I need to prune the old growth back in early spring? Do gardenias usually survive winter in zone 7? I would appreciate some advice on this. It was doing so well before I would hate to see it die. 谢谢!

    Hi Jennifer
    Gardenias are marginally hardy in zone 7B-with protection or a cold-hardy variety “Kleims hardy”, otherwise most are hardy in zones 9-11. It sounds like yours have been exposed to cold temperatures and that is why the leaves are tunring brown/black. It will not tolerate temperatures below 40F. If your plant is in the ground, cover it with a blanket and add a couple inches of mulch around the base of the plant to help protect the roots. If it survives the winter, you may have to prune away the dead stems in the spring.

  • 珍妮

    Thank you for answering my question above. I thought of one more thing to ask about my gardenia. If it does show signs of growth in the spring, can I transplant it into a large pot so I can move it inside during the next winter? I just wondered if moving it from the ground into a pot would kill it even more or would be ok to do. 谢谢。

    Hi Jennifer
    Gardenias do not like their roots disturbed, so it won't be happy for a while but leaving it outdoors for the winter will eventually kill it. Transplant your gardenia in late winter when it is dormant. Before transplanting, cut back some of the top growth up to 1/3 to give the roots less to feed and make the plant more manageable. Once planted water in well and give it a root starter to help stimulate new root growth.

    I have a Gardenia that is wilting , has some brown spotted leaves, and some leaves are crips and almost dead. 任何帮助将不胜感激。

    Hi Suzanne
    There are some leaf spot fungal diseases that will cause brown spots on the leaves. I suspect that it started with a watering problem. If the soil is wet and the plant is wilted then you have a root rot problem. Remove any spotted leaves as it can spread and avoid wetting the foliage. Its best to water thoroughly and less often. Let the plant dry slightly before watering again.

    Chlorosis on gardenia

    I live in South Florida and have a gardenia planted next to my east facing patio. Admittedly, I have not taken the best care of it over the years. Despite my neglect, it has somehow thrived, until recently. Over the past several months the leaves have started to turn yellow with the veins remaining green. I have tried fertilizing regularly with Miracid, but the problem persists and may even be worsening. I recently read that using distilled water, rather than tap water, may be better for gardenias. I have not yet tried that, but wanted to know if there is something else I should be doing.

    Hi Elena
    I'm assuming that your gardenia is planted in the ground. I would suggest that you test the soil ph, to make sure it is low enough(acid) to make iron available to the plant.
    Here are some other ideas, gardenias that are growing under cold conditions (below 60F) for extended periods can also become chlorotic (iron)because the cold temperatures reduce nutrient absorption. They don't take up as much iron causing chlorosis. Chlorosis is prevalent on the new growth . It can also be a sign of root disease caused by keeping the soil too wet.
    For a quick fix add chelated iron to the soil or spray it on the leaves. If you don't see any results in 2 weeks, try again. Another option is to apply ammonium sulfate or iron sulfate around the dripline of the soil. Follow the manufactureres label and avoid spraying any concrete, stucco etc as it will stain the surface. If that doesn't work then there may be a problem with the roots being unable to absorb the iron and you may have to improve the soil the gardenia is growing in.

  • Sooty mold
    I am at my mothers in Naples, Florida where her gardenia has a covering of black “soot” underneath leaves, on top of the leaves as well as on some of the branches. I was told to use detergent soapy water and “clean off” each leaf. 有什么事要我做什么? We have not seen any aphids or bug activity.

    Hi Elaine
    Insects such as scale and whitefly also produce honeydew which sooty mold grows on. The problem with sooty mold is that it blocks light from entering the leaves which inhibits photosynthesis (food production) which can cause yellowing leaves and leaf drop. Scale and Whitefly seem to be a favorite pest of Gardenia. For scale look closely on the stems and leaves for bumps that can be scraped off. If you brush against the shrub and little white flies emerge then you have white fly . Once you get rid of the bug, you'll get rid of sooty mold. 说起来容易做起来难。 If you have an insect problem, you can spray the plant with Orthene (acephate) Malathion or use a systemic (disulfoton) that is absorbed by the roots and renders the plant poisonous. Read the manufacturers label for safe usage.
    If your gardenia is underneath a tree that is dripping honeydew from an insect infestation, then you'll have to control the insect in the tree. Sooty mold should wash away with winter rain or can be wiped off with soapy water. for more info. http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn74108.html

    I received a potted gardenia in bloom with many buds for Valentina's. I put it in bathroom by large glass block window in large shower. Temp normal, cooler at night. I live in Melbourne, FL. It continues to bloom however the flowers turn yellow within a day or two. Leaves are green and shiny. I water when dry. I don't take a shower in that particular bathroom often What am I doing wrong and why do flowers turn yellow in such a short time. It's my favorite flower. My mom use to pin a flower on our slip strap as young girls for our perfume.

    Hi Eve
    Gardenia blooms in optimal condtitions will last for 3-8 days. If the plant is slightly stressed, the flowers are the first to show any symptoms. Perhaps it gets too warm with glass block window. Indirect light is better when in bloom. Flowers will fade faster is the air is too dry. It may need more humidity.

    Hello, I am considering purchasing a few dwarf gardenias , but have some concerns about size. Is it true that the dwarf versions only get to be about 2 ft. tall?

    Hi Chris
    I don't know about this gardenia cultivar but if the tag is labeled to grow up to 2ft., then I would think that it should be true. Perhaps someone out there knows more about this cultivar.

    I purchased a beautiful dwarf variegated Gardenia with double flowers, from 'X' nursery. True to its word, the Gardenia hasn't exceeded 2′.
    It's Gardenia 'radicans' variegata. A gorgeous plant.

    Gardenias prefer being potbound. Tight roots promote flowering, but also, the smaller the pot, the smaller the plant. I'm not saying to keep a plant confined indefinately, but smaller areas slows growth.

    Less fertilizer is another option. Althuogh, fertilizing gardinas with an acidic fertlizer is required, use half-strenght, once a month, during growing season. Halt in fall and winter.

    Someone asked why buds drop prematurely. Overwatering is the number 1 reason this happens.
    Less water and cool temps should do the trick..the problem is, the average household isn't kept chilly. Although a few of my friends turn the heat way down at night, even in our cold area. If a person can deal with eight hours at 60-65F degrees, and soil is left to dry, buds should open, turning into beautiful blooms.

  • My wife has 2 Gardenia Bushes and she would like to cut some of the blooms to put in the house. How do you do this without hurting the plant?

    HI Dan
    Gardenia flowers are usually cut with a few inches of stem attached. Avoid touching the flower, it will bruise and brown easily.

  • 爱丽丝

    My husband gave me his late Mother's gardenia tree about 3 years ago. I planted it at my home and it was doing great. About 7-8 months ago after our wedding we moved it to our new home. We were careful about having it in the “same sun” at the new location. Since moving it the leaves have become yellow and it's rather sick looking. Of course this has a lot of sentimental value and I don't want to lose this tree. Any suggestions would be appreciated. Help, please!
    谢谢。

    Hi Alice
    Your gardenia may be adjusting to the new environment. There are several reason why the leaves can turn yellow. Some yellowing leaves are normal, others may be because of lack of nutrients. First, check for insects such as scale .

  • Missy

    Its Missy again with another question… Its now starting to get warmer here in Northeast Conn. I have been putting my tree out when its 50 degrees and warmer to get some sun. Although now all my leaves have dried up and fell off!! It looked like there were new green buds for new leaves but they seem to have been drying up too. The soil is very moist and I try to spritz it down often. How do I make it come back? Do I trim it, do a half soil change? The stems of the tree are still alive and have green in them… help!!

    HI Missy,
    Be careful of how much sun exposure your gardenia is getting. Too much sun will easily scorch the leaves. In addition, make sure the gardenia gets a chance to dry out slightly between watering. They like moist soil but if it is too wet it causes root damage.

  • 艾莉

    Insect Problem
    嗨,
    I bought an indoor gardenia last year. It has started blooming again this March.
    I have seen small bugs in the pot, sticky residue on the leaves, spider web like webs on some of the leaves, and some of the new leaves look like they have been chewed.
    Please help me save this beautiful plant. 谢谢。

    Hi Allie
    You may have a number of things going on. Sticky residue is a clue for scale or mealy bugs. I'm not sure what is chewing on the leaves. You may also have fungus gnats in the soil if you kept the soil too moist.

  • Missy

    Dried leaves and drop
    Hello again, Its spring here and I have put my gardenia tree outside on those nice warm days but I am sure to not give it too much sun. Since I have brought it out from the winter all of its leaves have dried up and fell off . In the beginning of the winter I treated it for spider mites with Ivory soap and water and that seemed to do the trick. The stems have green to them I have fed it a week and a half ago and still no new growth. Is this a result from the mites? Any hints? or what should I do??

    Hi Missy
    It's possible that your gardenia tree is suffering from several problems aside from the insects, leaf drop can be due to a drastic change in temperatures (too cold) and light as well as keeping the soil too dry or too wet. They are tempremental. Keep the plant in filtered light until it shows new growth and slowy acclimate it outdoors to filtered light.

  • Judy Ellis

    Just got gifted with lush gardenia plant for Mothers Day. Tag says “Grown in Canada”. There are no blooms on it. Can I plant it outside in this 9A grow zone or is it strickly an indoor variety? I've got a couple spots in mind that are sunny til noonish then house shades it. Also have screened porch on same side, but I'm not to good about remembering to water stuff regularly. 感谢你的帮助。

    嗨朱迪
    Yes, you can plant your gardenia outdoors. It should survive the winters in zone 9A. Plant it in a protected area. The am till noon sun sounds great.

  • nadine

    嗨,
    I live in a very hot country (Dubai, uae) and recently(4 months back) got a gardenia plant which was blossoming in February.
    Now that the weather is turning hot the gardenia's leaves are curled down and some of it turning brown and it's not blossoming at all. Today, I moved it indoors hoping that the room temperature will help. Shall I move it back outdoors?
    Any advice how to revive it?
    谢谢

    Hi Nadine
    The drying and curling leaves on a gardenia indicate uneven watering and/or low humidity.

    Hardiness issue
    Hi, I bought a gardenia tree and I planted it outside.I was told that it was an outside plant and now I find out that it might not survive the winter outside in Canada.When I purchased this plant I was looking for something thatwould come back th following year without any problems.
    I am very upset it is a beautifull flower and would hate to lose it… help please…

    HI Tinka
    Gardenia is a tropical plant and will not tolerate freezing temperatures. The only way it will survive you winter is if you bring it indoors. I would complain to whoever sold you the plant giving you the wrong information.

  • I just received a gardenia plant as a gift. I bought a ceramic pot and transplanted it and added some Miracle Grow moisture control potting soil. I also added some Miracle Grow “stick” fertilizer. I have the plant in partial sun most of the day. I had it in full sun and noticed some of the leaves were turning yellow so I moved it to partial sun and the leaves look great. My only problem is “mold” growing on the top of the soil?? What is going on?? I did removed a “layer” of mold last night but it came back today. What should I do??

  • rosy

    I bought new gardenia few weeks ago with no experience in gardening and newely developed hobby.I am not sure what that yellow powder is on leaves.it is flowering and has new leaves.

    Not sure what the yellow powder is. Could it be under a blooming tree or shrub that is dropping pollen? If the powder is a light gray/white color then it could be powdery mildew .

  • mitchell

    i live north of Ocala, fla. my gardenia is about 6 ft. tall and roughly 6 ft. diameter. it is blooming nicely. do i need to pull off old flowers as they turn yellow or let them stay on plant? if i need to pull them, do i take flower and pod or just the flower. 谢谢。

    Hi Mitchell
    Usually the flower will fall off on its own. You can pinch off both the flower and pod. The pod (if pollinated) can produce seeds.

  • Kathy

    Pinch off flowers
    I have an outside gardenia bush and this year it is full of beautiful blooms. When the blooms begins to turn brown, do I pinch them off from the stem or do I prune them similar to roses.

    Pinch off the browned flowers, if you don't get to it, they will dry upand fall off by themselves.

    Gardenia growing tips
    I started one from a cutting 21 years ago and it still looks and does very well. I don't have any special secrets but this seems to work for me: I live in New jersey.
    I put it outside on my front porch from May 1st to October 1st and only feed it during that time. My porch gets afternoon sun.I feed it every 4-6 days with a pinch of Muracid to a gallon of water and let it run through.
    Before i bring it in for the winter I spray it with an all purpose bug spray and cover it with a cleaner bag for the night. Then I trim it.
    Once inside I put it in the brightest room in the house-my diningroom and water it less often and do not feed it. It sets bud over the winter and blooms on the porch over the summer. I get about 50-60 blooms.
    I repot it in the spring every few years when roots are coming out of the bottom.

    Thanks for the info Lynn. I'm sure it will be useful to our readers.

    Transplant time
    After reading the many informative posts on your website, I now see that my outdoor gardenia plant, which I planted in full sun, needs to be moved where it can be in partial sun. I live in Seattle, in Zone 8b. However, I see that you strongly recommend not disturbing their roots. Is there a good time to move a gardenia? It is now July, and I planted it about six weeks ago.

    您好米歇尔
    The best time would be when the gardenia is dormant-in the fall or late winter.

  • seth akshay

    i live in northern va and have just bought a gardenia jasminoides 'aimee'. It is about 3 feet tall and is potted. As adviced by the nursery i fed it Miracid, however its leaves started getting yellow. i would like to know how to take care of this beautiful plant. The zone of this area is 7b.

    HI Seth
    Some leaf yellowing is normal. Miracid is a good fertilzer for Gardenia. It may take a week to notice the difference. Are the older leaves turning yellow or the new leaves? You can plant your gardenia outdoors as it it hardy in zone 7b.in afternoon shade. Plant it in rich, well-drained slightly acid soil. Once planted, water well and place 2-3″ of mulch around the plant, keeping it away from the base.

    Drying and curling leaves
    嗨。 I live in Atlanta. I replanted my gardenia last spring. but after i did. the green color of the leaves seems to fadded, it is not losong the green color, very dry leaves and curling at the end. what to do?

    您好纳奥米
    The drying and curling leaves on a gardenia indicate uneven watering and/or low humidity.

  • Pat

    One more variation on the endless yellowing leaves issue: This spring, I planted some Radicans dwarf gardenias in a relatively low-lying bed that has tended to stay damp. Recognizing that, I planted them fairly high, did the best I could to prepare the hole for good drainage (underlying soil is clay), and tried not to irrigate too heavily. Half of the plants seem to be doing well, while the others are thin and have many yellow leaves. Contrary to what I would have expected, the plants doing better are in the section of the bed I think is the dampest. How likely is it the the yellow leaves on the others are due to being UNDER watered? The surface of the soil does dry out between waterings. Any other thoughts? We've had our soil tested and it is acidic. Site is mostly sunny, zone 8. 谢谢。

    八喜
    I'm asuming that you checked for insects and nutrition problems. It is possible that the yellow leaves are due to not enough soil moisture. Gardenias like slightly moist soil. Try placing 2 inches of mulch around the root zone of the plant. This will help keep the soil moist longer.

    Winterover gardenia indoors
    I purchased a blooming gardenia in April, repotted it and put it in a sunny spot outside. I live in Missouri. It's grown considerably! I only had one bud on it, then we had a rain storm and the bud knocked off (no more buds). Now day temps are only in the mid 60's with nights in the 40's. I have doubts that it will survive the winter indoors because windows are east/west exposure. Do you think I could just put it in the basement and let it go dormant for the winter and revive again in the spring? I've never had success with indoor gardenias over the winter. HELP please?

    Hi Sylvia
    I have never tired it but as a last resort, I think its worth a try. Other tropical plants can be wintered over the same way. Just make sure that the soil doesn't dry out completely-water it lightly once a month.

    Perhaps someone else out there has had some experience with this method.

  • 梅根

    Leaf drop
    I brought my gardenia inside for the winter…and it was fine at first, but now ALL of the leaves are dropping off. 这是什么意思?

    您好梅根
    Lower light and dryer air can cause your gardenia to drop its leaves. Provide bright filtered light, uniform moisture and humidity (place it on a pebble tray)
    Are the leaves turning yellow before dropping ?

  • Yellow gardenia
    We have a whole bed of Gardenias that has been established for approximately 30 years. We live in Georgia (2 hours north of Atlanta) and have enjoyed the pretty white flowers every year. Today (Nov. 26, 2009) I noticed some orange colored blooms on them. There aren't as many orange blooms as white ones in the summer but they are there none the less. At first I thought maybe there was another plant (like a weed) that had invaded the bed; but, the blooms are squarely on the Gardenias. Would you give me a 'heads-up' as to why they are there? We have never noticed them in the 30 years of the bed's life. Thank You in advance for your answer email.
    此致,
    Robert Fricks

    Hi Robert
    There are a few rare cultivars of gardenia that produce fragrant orange flowers such as Gardenia Kula var. gradiflora, gardenia tubifera kula (gardenia pfordii), gardenia gjellerupii. The color changes from ivory, to yellow, then turn orange as the flower matures. They are slow growers. As to why you have yellow and white growing together. The only thing I can think of is that perhaps you had the rare cultivar among the white gardenia and the orange gardenia finally started to bloom. No wonder they are so expensive.
    If you have both colors on one stem???? Perhaps you're growing a new sport or chimera.

    Dried out soil on gardenia
    嗨。 i have a small indoor gardenia (about 10″ tall) that i've had for a few months. i went away for a couple weeks and left 2 water globes in the pot to feed it. on my return a week ago, i found that only one of the globes was drained and the other had been blocked from draining by soil. needless to say, the pot was dry and as were all the leaves. i watered it immediately, and haven't seen a change. i haven't pruned it yet, but i'm just wondering if it's gone to that big garden in the sky.
    谢谢

    Hi Devon
    Sorry to say, your gardenia has gone to the “big garden in the sky”. (I like that phrase). Once the soil dries out completely it is very difficult to rehydrate and by then the roots are dead.

    I have (had) a lovely gardenia florida on my back verandah potted in premium mix. It was going very well until just now. Yesterday I noticed a couple of leaves on the deck but did not take any notice. This morning I noticed alot of leaves and when I touched the branches a whole lot more came off! I ended up cutting it right back and will wait to see what happens. It has been well watered and fertilsed. I would just love to know what I did wrong!!

    Hi Rossop
    Is it possible that your gardenia was exposed to sudden cold temperatures? If so, it would drop its leaves very quickly. ps的。 Do not fertilize the plant from Sept. to March.

    Curl grub
    Thanks alot but I found out the cause of the stress to my gardenia. It was curl grubs. I am growing a new one in new potting mix. I was told to water with confidor every 2 months. Any other tips?

    Hi Rossop
    感谢您的信息。 Curly grubs are the larval form of a beetle (Chafer,Christmas, scarab, garden beetle) that feeds on the roots of plants. They are all lumped together because they belong to a large beetle family(Coleoptera). You will get specific grubs, depending on where you live. Curly grub seems to be prevalent in Australia and Southern states (USA). Treatment is the same as for Japanese beetles. Merit and Milky spore are some products that will help control the insect. Note: Milky spore needs to be applied in early spring before the grubs hatch.

    Black crispy leaves
    Please help my Gardenia, I am in Toronto, Since I migrate it indoor in Winter last Oct., It's began to dry the leaves as picture,fall after I touched it,the leaves look crisp. I checked the soil, still humidity, Please help!!!
    This is take from last summer
    I don't know how I can keep it until this spring and bring it outdoors.

    Gardenia picture here
    http://www.flickr.com/photos/duduhome/4317135835/in/photostream/

    Hi Dudu
    Thanks for the photo, it looks like your gardenia may need more humidity and perhaps is experiencing uneven moisture such as forgetting to water the plant thereby allowing the soil dry out. Keep the soil moist but not wet. Make sure that the plant does not sit in water. Being a tropical plant, gardenia also needs lots of humidity, a pebble tray would help provide extra moisture in the surrounding air to keep the leaves from drying out. Make sure that the plant is away from cold drafts as that can also cause the leaves to turn black and drop.

    • Soluble salt
      感谢您的意见。
      I was told by the gardener guy that may cause by Salt built in the soil, and suggest me to put it in bathtub and completely show through the plant. It's so sad to me for the Plant tree was brought for my wife's birthday gift last year. Because the flowers are so wild in my hometown(south-east of China). Now I don't know how to take care of it.
      Should I bathe it? It's getting worse now. How am I going to watering and fertilize? I used to water once a week.
      By the way, will the tea help it built acid condition? Can I mix some tea with the soil if I am going to re-pot it?
      Many thanks

      Hi Dudu
      Soluble salt build up can also be a problem.
      Excess soluble salts is an accumulation of soil salts (mineral deposits) from fertilizers and or dry soil. New growth will blacken and the leaf tips and margins of leaves will turn brown. You may or may not have white/yellowing crusting on the surface of the soil. 这发生在你没有水的正确。
      要解决此问题,滤出由植物浇水您彻底得到所有过剩的根源湿土壤盐。 Pour water until it flows out of the bottom of the pot and then do it again. 过量盐会冲刷与排水。 Make sure water drains from the bottom each time you water.
      Because the plant is hardly growing during the winter, it does not need any fertilizer. Fertilize your plant from March to Oct..
      Using tea compost can be a benefit to the plant and the tannins in the tea may slightly raise the soil ph. I water my acid loving plants with leftover tea and coffee and they seem to grow well but keep in mind that your gardenia may still need supplemental nutrients which it will get from a balanced fertilizer.
      If you can place your gardenia outside in the summer so that it can enjoy warm humid weather. 我希望这有助于。

    My gardenia is lush and growing quickly,but today I noticed what looks like light green scales on a few of the branches. It looks like it just started, but, I would like to take care of this problem before it damages or kills my plant. Are the scales dangerous to my gardenia and if so, how do I get rid of them.
    Thank you in advance,

    Hi Dee
    It's good to nip the problem in the bud, before the scale get out of control. See scale for treatment recommendations. Don't use insecticidal soap on gardenia as they have a tendency to be sensitive to soap sprays causing phytotoxicity(yellow/brown spotting and burned tips. An ultra fine horticultural oil will also work on scale. You may need several treatments to control the problem.
