A. This is a inquiry I obtain asked commonly so i willpost that on my blog an extremely soon. For this reason you room the happy winner and I will soon postyour question and the prize I administer below! Bougainvillea will not toleratetemperatures below freezing without part damage. The level of damages willdepend on just how much listed below freezing the temperature dropped and for how numerous hoursand if there to be windto go along with those low temperatures.
In order to answer this I desire to describe a couple of thingsabout winter tender plants and also how to manage them in general an initial before Ispeak directly around bougainvillea. Winter tender plants must be"hardened off" prior to freezing weather. This is by not fertilizingthis plant through nitrogen fertilizers a pair of months prior to freezingtemperatures and reducing the frequency the watering. In the las Vegas valleyfreezing could be as soon as December 15 and,rarely, also soon than this. So typically speaking carry out not fertilize any coldsensitive, aka winter tender, frozen sensitive, frost sensitive, etc. Plantsafter mid September. Secondly, begin giving this plants less water come improvetheir winter hardiness.
Those room the textbook answers. In reality holding backon water is very daunting to do with automatic watering systems. Friend SHOULDbe cutting earlier on watering top top all your plants in your landscape anywayat thattime that year. Theeasiestthing come do and also most reality is come stop using fertilizer in late summer. When youfertilize these plants and also encourage growth late in the year they can pushnew succulent expansion which will be moreeasily damaged in freezes.
Cover the plant through something if girlfriend hear it mightfreeze that night and removethecoveringin the morning a pair hours ~ the suncomes up. If you use plastic, this plastic need to alsocover other thatreleases warm backunder the plastic. This have the right to be a warm, south dealing with wall,the soil beneath the plant, large jugs of water the was warmed throughout the day,rabbits through their long warmth create ears, etc. Do not just wrap the plantin plastic or it will freeze and also itmay possiblyget also colderinside the plastic 보다 the outside. Blame the on physics.
The other trouble is wind. Cold and also wind togetherare moredamaging 보다 either alone. Try to save the winter wind indigenous the tree so anenclosed courtyard, patio or other protected area of the garden is a good ideafor locationfor planting.

As the plant gets older and also larger the will stand up to afew extra degrees. Its root device will also be larger and also capable of storingmore food. When freezing weather death the peak to the ground, the root andcollar region will regenerate the top an extremely quickly. Just give it lots of water(bougainvillea likes deep watering) and fertilizer so it recovers quickly. Iftemperatures drop come the teens it is feasible you could lose the whole plantso make sure the soil is mulched with number of inches of lumber or rock mulch toinsulate the roots and collar as much as possible and offer it some extra protection.
