Gladiolus
Winter care of gladiolus
In areas with deep frost, gladioli need to be lifted from the soil. Dig up the corms before the first frost or when the tops die back. Remove browning foliage and trim it to 1/2 inch of the corm. Shake off the soil and let the remaining stubs dry for 1-2 weeks in a warm, ventilated area. Once cured, remove dried stubs, discard old corms and cormels (optional). To prevent rot, dust the large new corms with a fungicide. Store the corms in a ventilated container such as paper/plastic mesh or cloth bag in a dark, dry, frost free place at 35-45 degrees. Cormels can also be stored and planted the following spring.
You can also drop a mothball in each bag of gladiolus to deter mice and kill overwintering thrips.

Do you cut gladiola stock before winter or in the spring?
Do I need to cut back my gladioli for winter, or dig them up? I live in upstate NY, where winter temps can hover in the 20’s.
Stephanie
April 11 in NY – I checked the bulbs I had dug up and put away for winter. Guess I did not dry them out sufficiently, and now they have about 1 foot long white leaf? growth. What can I do? Any chance to save this batch?
No blooms
I planted gladiola bulbs last year and the green stalks came up with no problem. However, there were never any blooms. Again this year, they all have green stalks, but no blooms! Help!
Cut flower care
Anything I can add to the water to make the blossoms last longer after cutting and making a bouquet. I hear peroxide, also something sweet like 7-up or such. Thank you.
Gladiolus Thrips
hi. i have grown glads for many years. this year my glads look dry and they are all wilting when it is time for them to open. we had a dry spring/early summer, but i watered them often. about 200 corms, some new this year, and all are the same way. any ideas? thanks
I LIVE IN CENTERAL MN. I’M HAVING A DEVIL OF A TIME WITH THRIPS THIS YEAR. WOULD YOU SUGGEST DISPOSING OF ALL THE BULBS AND STARTING OVER NEXT YEAR? I USUALLY DIG THEM UP, DRY, AND THEN DUST THEM AND STORE IN A MESH BAG. WILL THE THRIP SURVIVE IN THE BULB UNTIL NEXT YEAR? THANKS FOR THE ADVICE David Mumm
Insect problem
My gladiolus are about a foot high now and I am noticing holes in the some of the leaves. Some leaves have fallen over because of this. I can’t see any kind of bugs. What might be causing this?
I want to dig up all the gladiolus bulbs I planted this year over 40 and put them in another place where it won’t matter when the plant doesn’t look so good. Do I wait for the green stalks to die out? The flowers are done. They could’ve stayed in the ground until next year if I’d chosen a better spot. Do I plant them now in their new spot or wait until next spring? I live in Southern California.
Short bloom time
My Gladiolus have blooms but they only last a five days and die . Do they suppose to do that or do they suppose to continue to bloom the whole summer. How can I get to bloom continue to bloom.
I live in Ottawa, Ontario, Canada. I have no experience planting bulbs, but I ordered some before spring hoping to make it a learning experience with my kids. Unfortunately, they arrived late and I wasn’t able to plant at that time. I have Gladiolus Mix, Freesias Mix, and Windflower Mix (Anemone De Cean). Can they still be planted now or is there something I can do to preserve them for planting next spring?
Leaning Glads
My Glads are doing fine and flowering nicely
but want to lean and tip over, can you tell
me why.
i JUST WANT TO KNOW WHICH CHEMICALS CAN I USE FOR FLOWER FORCING AND INDUCING AND I ALSO WANT TO KNOW WHAT CAN I USE TO REGULATE GROWTH

Biological control
I love the way glads fill in ‘holes’ throughout my garden and plant many late spring thru early summer. Is there some way of orienting the bulb so that the flowers blown on a particular side of the stalk? Invariably, I’ll have several that bloom facing a wall or my neighbor’s fence (lucky for him I guess) Also, this year I had a thrip investation for the first time. I plan on following your tips for preventing over-wintering of the nasty little things. I’ve heard that lacewings and/or planting alyssum are effective bio-controls. What is your opinion? Thanks!!
Plant to bloom time
I live in southern Missouri. I want to plant Glads inside in pots so they will be in bloom by June 20. When do I need to plant the pots?

Hardy glads?
We planted glads about 4 years ago and have left them in the ground and they continue to flower each year.We live in central Ontario were the temp can drop close to -40. Have we just been lucky or do we have temp resistant variety?
I live in southwestern Ohio and I want to plant a large whiskey barrel ( well dried out of whiskey ) of gladiolus, is this possible?
Planting gladiolus
I just purchased a large bag of Gladioli bulbs and have been told to plant them in 2 week intervals so that I will have blooms all summer long. Has anyone ever done this? I have a bed in the front of my house that I was going to dedicate only to these plants. Does anyone know how far apart they should be planted? I have 100 bulbs total.
I purchased gladioli bulbs last winter and kept them in my basement. When I took them out, they looked very dried out, possibly dead. A friend told me to soak them in water for a day or two – is there any want to tell if the bulb is dead?
after my gladiolus blooms die, should i pull off the dead blooms or cut the stalk?
Grow Glads from seed
Can glads be grown from seed? If so how?
Any suggestions to make the dying leaves less unattractive in my garden? It is August in zone 6 here, and all the yard high leaves are laying on the ground and are brown at the bottom. I had beautiful flowers a few weeks back. Thank you.
Glad seeds
Hello…I planted my gladiolus, they grew, and now they are not blooming, i have noticed that where the flowers were at it is growing something, but not sure what. I’m not certain if I have to cut it..and if I do, where do i have to cut it…how far from the ground should I cut the stem?…Thank you I appreciate your help!
GLAD SEED CAPSULES
August 4th, 2009 at 6:15 pm · Reply · Edit
Hello…quick question. Can you tell me what the “buds” appear to be that are growing out of where all the gladiola’s flowers were? Much appreciated… Thanks from Staten Island, NY sKYE
Hi Skye
The “buds” are seed capsules.
Seed capsules
Hello – will flowers bloom again from these seed capsules? I just planted my first batch of gladiolus this past Spring and they’ve all bloomed beautifully. Now that the flowers have died, these buds or seed capsules have appeared. Does this mean they will bloom again soon? Does each gladioli bulb bloom just once per year? I live in Southern California – zone 9. Thanks.
Hardy zone for glads
I live in Arkansas and planted glads for the first time this year and they did ok, although not alot of flowers. I love them but have decided I want to move them to a different location. I can dig up and move now (Sept) or do I have to dig up and store the bulbs? What’s the worst thing you can do to bulbs when you are storing them?
Planting cormels
Can the new cormels be planted inside to help them grow? would they be plantable the next year?
Hi,
I think I may have killed off all my corms! To begin with, I dug them up very late (yesterday). I’m in Michigan, so the ground was already very hard at least an inch down when I was digging them out. They all looked really good, and I was excited to see how so many of them had two and three new-growth corms on them. After preparing the cormels, I got distracted and left all my corms (80+) outside!! The temperature dropped below 30 degrees last night. When I realized I had left them out, I was so sad, but decided to try and save them anyway. I rinsed them all, and they are now in my basement on cooling racks (the ones used for baking).
I did see the response about cutting one open and checking the inside, and I will do that with a few of them, but I’m wondering if I should even bother trying to store them at this point. They were so beautiful this summer and I’m so mad at myself for having left them outside last night!
Thanks for your advice.
Separating new and old corms
We have had a VERY wet fall here in Vermont. I dug up my glads about 1 month ago and left them in a warmish basement with the dead foliage still attached spread out to dry. They were quite muddy when I dug them up. The mud is dry and has fallen off. Today I was breaking off the stems and the old corms. My question is, can I break off the old corm too early? The bulbs are very firm, and when I break off the old corm, it looks like a hard moist cream colored bulb where the old corm was still attached. Is that OK? I did it with a few last week and the bulbs still seem firm. I then plan to put them in a root cellar we have that kept them very well last winter. (I did this with glads that I have about 50 of the same color and am waiting on the other color ones till I hear from you. I hope I have not messed them up!
Thanks
Sue
Bloom time for gladilolus
Need some advise please !!! I live on the central coast of CA. Very mild climate. I want to know when would be the best time for me to begin planting my Glads, so they are
blooming by Memorial weekend so my 94 yr old Grandmother has plenty to take to the cemetery. Thanks Patti
Winter glad care in warm climates
Hi,
I purchased, last July, 10000 gladiolus corms from Holland and planted them in Beirut – Lebanon; I harvested around only 4000 flowered stems after 3 months, all the remaining were only green leaves. Here the temperature never falls below 0 Celsius in winter. For this reason I think the green leaves won’t die, so what I am supposed to do if I want to prepare for a good flowering season?
P.s. the corms were not small but 10/12 and 14/16.
Thanks
Wassim
I just planted my glads in how long will I see sprouts
Color change in glads
Very perplexed…. Years of successful glads have now changed from an array of beautiful colors to mostly yellow. What has happened to the wonderful rainbow of color that we have enjoyed for so many years (20)Have they seen there peak or is it something else ? ? ?
Planting to bloom
My glads have sprouted now in about how long will I see blooms
i planted my glads about 4 1/2 inches deep. do you think it is too shallow since the corms form on top of old ones?also, they are about 7 inches tall and have one leaf, do more leaves come out of the thick sections?
Glad hardy zone
I live in the Seattle area and am planting gladiolus for the first time. Can they winter over in the ground in this area or do I need to dig them up. If I plant some in containers, can I leave them in the soil, in the containers,placed in the garage for the winter or do they also need to be dug up? Thanks for the help.
Planting time
I live in Columbus Ohio and just bought 80 bulbs. I read on the barrel at the store that
these can take 10 weeks to sprout. If this is the case then if I plant them around April 1st they should start sprouting close to the second week of June. Is this true? I have never used this kind of flower before. I don’t want to plant too early but would like to see some blooms the end of june first of july.
Hi, we live in Southern Ontario and planted Glads last year. They all grew well, perfect height and flower bud development, but as the flowers began to open they would only develope to about half open and then began to wilt or stop opening all together. Each plant reacted identically this way began to open and flower then stopped and wilted with none at all every opening properly. The soil conditions seemed to be in good order, and we had almost perfect rain conditions the entire summer. Could this be a result of the thrips infestion that I have seen spoken of?. Or could it be to other conditons we are unaware of?. The flowers as well all opened facing to the east of the garden and towards the back side of the plant rather than facing the front of the garden. The garden runs along a fence but the plants are a good three feet out from the fence could this be a result of heat and light reflection off of the fence by chance?. Any suggestions you may have in these regards we would be most grateful to hear. thanks.
Grow glads in mulch
I have some Gladiola bulbs and I wondered if I could plant them in straight mulch? I have a wonderful flowerbed that I have filled in with mulch and wanted to plant my bulbs in there. Will they grow?? Thanks!!!
I planted my glad bulbs about 4 weeks ago. I have noticed you tell everyone it takes about 90 days before blooming, but I’m curious to know how long it takes for them to just pop up out of the ground. I live in southern Arkansas if that information will help any.
Hi, I have a question. I’ve had a lot of glad bulbs that we’ve planted and dug up every year, and gotten beautiful blooms. It’s almost time now to plant them again, but unfortunately, we just found out that we’re moving to Alaska in August. Can our bulbs be kept in storage for more than just over one winter? We would be back not next summer, but the following. I just can’t bear to think of planting them all and then not digging them up this September. And we have so many of them. Also, we live in Zone 4, where it’s not really possible to leave them in the ground over winter.
Thanks.
Bloom time
Hi! I am in chicago and planted gladiola bulbs in pots towards end of March / early April. While the plants have excellent green leaves, which came very quickly – till now, there are no signs of blooms or buds even. On the advice of the store, I put in a sprinkling of ‘Miracle Grow” fertilizer at the base of the bulbs. It does not look like they have thrips, and they are in good sun. Could it be the fertilizer or do they bloom late?
Grow in Cambodia
Hi there, I just bought some gladiolus bulbs from Italy to grow in my country, Cambodia (tropical country). Can gladiolus grow there?
Hi. I live in the Seattle area and planted 20 new Glad bulbs in groups of 10 each in two large containers. The green foliage looked good and then about 1/3 of all the leaves started turning brown. I know I’m giving them plenty of water and used good potting soil for them. Also, there is also no sign of any flowers at this point but my neighbors have big flowering stalks growing in theirs. Can you tell me what is going on?
Hi Brittany
Do the leaves first turn yellow then brown or just brown from the tips down?
If I get some glad bulbs on sale now and plant in July in zone 8 can I leave in ground over winter. How long does it take for a 6 to 8 CM bulb to bloom and how fast does a corm/bulb grow in zone 8? Thanks for any help here.
i planted my gladioli, all i have is a bunch of stalks and no flowers, the stalks are over 12 inches, when will the flowers bloom
