Bougainvillea winter damage

I recently moved to Jacksonville, Florida and we planted a pair of bougainvilleas 20 months ago. They seemed to thrive last year even through the winter and are now about 5-6 feet tall. Last week we had a rare freeze where the temperature dropped to approximately 20 degrees F. Now the plants have lost all their leaves. Is there any hope the the plants will survive and is there anything I can do to help at this point?

Bougainvilleas can recover from some frost damage as long as the roots were not frozen. The amount of damage will depend on how low and how long the plant was exposed to freezing temperatures. They will tolerate temperatures as low as 30-40F for a short time.  Not much you can do at this point but to wait and see.  Wait until all danger of  frost has passed in your area.  See if some of the damaged branches recovered.  They may surprise you and re sprout with new growth in the spring.

Once you asses the winter damage, you can prune your bougainvillea in early spring.   If you prune too early and get another frost, any new growth is especially sensitive to frost and will be damaged.

Cut the plant back by 1/2  and prune out any dead stems and leggy growth in early spring.

Begin fertilizing monthly when it starts putting on new growth.

If another frost is eminent cover your plant with a blanket.

    Wintering bougainvillea

    Hi I live in Albuquerque, NM and have three beautiful bougs. All are quite big and are planted in large pots. I’ve heard about taking them in for the winter so they won’t freeze. So my question is, do I just store them in my garage (zero light) until spring or do they need light during their dormant period? Thanks for your help!

    Hi Michele
    You can store your bougainvillea in the garage. When you stop watering the plant, it will drop its leaves and induce dormancy. It does not need light during this time. Check the soil about once a month for moisture and water lightly just enough to keep it from drying out completely. Bougainvillea can tolerate dry soil more than other wintering tropicals so err on the dry side. Once temperatures warm up and danger of cold has passed, it will begin to sprout. Move the plant outdoors to sun, prune unruly branches or to shape the plant and fertilize.

    Winterover bougainvillea
    Hi, I bought four gorgeous boug plants at the garden center. I live in Red Deer Canada. My intention was to keep them indoors and they will remain in their pots. Much to my horror and dismay, they are experiencing almost total defoliation! Some leaves leaves appear dry and brittle, and some appear a little soft, but all dropping. I spoke to someone at the nursery, and he said they become traumatized from moving. They may not be getting enough light, so I asked about supplementing the sunlight they get with a plant light. It was suggested to wait for a few more weeks, but now all I have are what looks like thorn vines. Would anyone suggest anything else for me do? Would it tramautize them more to get the grow lights? I am watering very sparingly, as I have heard they like to be on the dry side. I would really appreciate some advice, before it is too late. I would just hate to lose them all. Is there any hope of them coming back? Thanks in advance!

    Hi Grace
    Your bougainvillea has gone into a dormant stage. It would need lots of light and warm temperatures to get started again. My suggestion would be to store it in a basement or cool area for the winter. During this time water the soil periodically (once a month) to make sure it doesn’t completely dry out. Bring it to light in early spring when temperatures start to warm up.

Since it is quite a large pot I am reluctant to to move it to my garage. Do you have any alternative ways that I can frost proof it instead?

    HI Linda
    To winterize your bougainvillea just like mandevilla: They tolerate temperatures 30-40 F and then will drop their leaves and go dormant. Wrap the container with insulation and cut the plant back by 1/2 if needed. Once the leaves fall will off after a frost, mulch the top of the soil(4″) to protect the roots. Survival will depend on the severity of cold temperatures.

    Winterover
    I bought a bougainvillea and live in Vancouver, BC Canada. Can I leave it outside for the winter? We do not have harsh winters but they get cold. How could I leave it outside for the winter?

    Hi Deborah
    Bougainvilleas are hardy in zone 9-11 sometimes zone 8. It will tolerate temperatures as cool as 30-40 degrees for a short period of time but will need protection. During a cold spell it will drop all its leaves or worse freeze and die. If you want to leave it outdoors, plant it on the south side of the house and cover it with 4-6 inches of mulch for the winter and hope it survives. You can also store the plant dormant in a garage .

    I also live in Vancouver, BC – my young bougainvillea lives in a pot on my condo deck. Last winter I left it outside during the winter, it dropped it leaves and I thought it had died. Happily it has made a miraculous recovery this summer with some new shoots and leaves. But it has not flowered this year? I’ll be keeping it inside this winter, poor thing!
    I’m thinking about getting it into a bigger pot, is there anything I should do to make this less traumatic for the bougainvillea?

    Hi Victoria
    Bougainvillea respond to blooming when they are slightly stressed- crowded roots and the soil kept slightly dry. I would leave it in the same container. In addition, blooming occurs on new growth and balanced fertilizer w/ micronutrients during the growing season would help stimulate bloom. There are also varieties of bougainvillea that bloom in the fall in response to short days. see http://hortchat.com/info/bougainvillea-winter-damage for more info.

    I didn’t go to your site quick enough and my husband thought the tubers/bulbs had to be removed just like the dinner plate Dahylias. Darn it, I guess just throw them away? Should I try the process you use for the Dahylias? Thanks Rosalind

    Hi Rosalind
    I’m not sure we are talking about bougainvillea. But if it is some type of tuber you can try to keep it like a dahllia over the winter and see what happens.

    I live in Jax Fl. My bougainvillea was purchased this past spring and tripled in size. It was beautiful. Its roots went through the pot and down into the soil. We had a cold snap (29F) so I covered the plant. A few days later I noticed the leaves were falling off and it took on a thorny look. I dug it up, placed it in a large pot and placed it in my den. Poor thing, its a sight to behold. Can I move it to my garage? Will it revive when spring comes.

    Hi Gwen
    I would move it to the garage and replant it in the spring. Check the soil for moisture once a month so that it doesn’t totally dry out. for more info see..http://hortchat.com/info/bougainvillea-winter-damage

    Certain bougies can survive repeated frosts under the right circumstances. We live about 7 miles from the Pacific Ocean in the Santa Moncia Mountains at the 1,000 foot elevation. It is one of the coldest coastal canyons in So. California. Nighttime tempratures regularly fall below freezing between Thanksgiving and Valentines Day. Don’t know why–topography, I guess.

    We planted a hardy bougie (a variation of the purple-flowering B. spectabilis)on the eastern side of a masonary wall. It has grown up and over the wall, where it gets the western sun. Every year, it loses its leaves and the outer branches become brittle and die off. I trim it back hard to the living wood in the spring. It gets no fertilizer and almost no water from me, and yet it thrives in the summer heat, flowering more profusely every year. My kind of plant! The only downside is dealing with those nasty thorns while pruning. Ouch!

    Thanks for the input Bob!

    Cold damage
    I bought 2 Bougainvillea’s last summer and planted them in front of some lattice we have that’s in front of the pool equipment. They looked great all summer long and well into fall. As soon as we started getting frost warnings I covered them with burlap until the temp got above 34-35. they have both lost all their leaves and the branches look dry and dead. Should I prune the branches back to the main stem or just leave them alone and see what happens after it starts warming up. we live in zone 9. Thanks Craig

    Hi Craig
    I would wait until the weather warms up to see exactly how much of the stems died before pruning.

    I live in Sacramento, CA I have seen several beautiful flowering bougainvillea’s in many neighboring yards.
    Our’s survived 2 winter freezes but this last winter it didn’t make it. I have noticed that the yards that have surviving bougainvillea’s have them planted in between two structures, such as a garage and house or inbetween two houses. Do you think that has anything to do with them surviving the frosts, year after year?

    Hi Slunny
    Yes, the structures provide a microclimate of protection during the winter.

    my bouganvillea is so high what do i do to protect during winter do i trim it all the way down or what do in do we live in west tx and shes so beautiful right now long vines and beautiful flowers

    Hi Tonie
    Bougainvillea will require winter protection if temperatures fall below 32 degrees in your area. A mature plant will survive cold temperatures better than a new plant. It may survive the winter in W. Tx. but some winter protection is needed. A frost blanket and holiday lights draped over the plant can protect it when a frost is emminent. It should be removed when a freeze is over. Keep the plant moist during the winter.
    Bougainvillea can be pruned anytime but best time to hard prune is do it after bloom.
    If the plant remains outdoors, prune it in late spring so that you can remove any winter damaged parts of the plant.

    I live in zone 8…Pensa, Fl. and ‘I’m new to growing Bougainvilleas …’have kept most of them in pots, and store in the garage over the winter months. They do well there, but sure uses up the room. I’d like to plant them outside but concerned about our winter’s low temperatures. Do you think it’s necessary to cut them down to the ground and cover them as I have done with one that I’ve experimented with in this zone? ‘Just hate cutting off all that growth that produces late blooms the next season, and then more cold weather to contend with.

    Hi Jean
    Bougainvillea is hardy in zone 8-10, so you are on the edge of hardiness. They will tolerate temperatures as low as 30-40 for a short time. You may not need to cut it back now but gamble and wait to see what kind of winter you will have. If it is severe, the plant itself will die back to the ground on the other hand if you have a mild winter then you may not need to do much pruning. I would still add a few inches of mulch around the roots to winter protection and cover it when temps get below 30F.

    i brought a bougainvillea with me when I relocated from Florida to Maine. It bloomed poorly spring and summer in full sun. I decided to let it die a natural death for failure to thrive. I left it it its pot out in the Maine snow and sub zero temps. Last week I approached the pot to take to the dump, and to my amazement, it had a new 30 in. growth from the roots. I had no idea this was possible.

    Hi Bill
    How about that! I wouldn’t think that was possible. If the pot was buried and covered in snow, it must have been reaping the benefits of snow insulation.

    I bought to large braided bougainvillea toparies at a garden shop last spring. Well Before our first frost here in Centeal Texas I put the large potted plants in an outdoor shed for overwintering. I watered them every month or so. I pulled them out a couple of weeks ago and the plants look dead. The shaped ball on top is all brittle twigs. When scratching the plant skin to find life I have to go almost half way back down the braided stem. I paid $400.00 each for two of these. HELP!!! Please tell me there is still a rescue plan for these two!!
