Will bougainvillea die when it sheds leaves in winter?
Let me share with everyone the explanation about whether bougainvillea will die when it sheds leaves in winter and the steps for新手 care of bougainvillea in the aspect of green plants and flowers. Below, the editor will give you a detailed answer.
Bougainvillea is a kind of flowering plant that many people keep. It is very beautiful when it blooms, and the flowering period is relatively long, allowing it to bloom multiple times a year. However, the bougainvillea bought by oneself easily sheds leaves, eventually leaving only a bare stem. At this point, many people think it has died and throw it away. In fact, there are reasons for the bare stem caused by the shedding of bougainvillea leaves, and we can quickly revive it by finding the cause. Today I will tell you about the four causes of leaf shedding, and you might be able to save it through these four points of judgment.
1. Root Suffocation leading to Leaf Shedding
When we keep bougainvillea at home, many people raise it in a closed balcony and use garden soil. In this case, after watering, the soil does not dry for a long time, and its roots will suffocate, leading to poor root respiration, which causes the leaves to fall off, leaving only the stem, and the top of the branches will also show blackening and contraction.
If you find this situation, quickly prune it, cut off the thin and weak branches, trim the blackened tops, then change the soil to a loose and well-ventilated one, plant it in a small pot, and place it in a well-ventilated position. Water the soil when it dries down about one or two centimeters. If all goes well, it will recover growth in half a month to a month, and then it can grow normally and bloom again.
2. Low Temperature leading to Leaf Shedding
Bougainvillea is a heat-loving plant and can still grow normally even when the temperature exceeds 40 degrees. However, some varieties will start to show yellow leaves and shedding at around ten degrees, and most bougainvillea varieties will shed leaves when the temperature drops below five degrees. When the temperature is below zero, it will freeze to death or get frostbitten. So, if your bougainvillea sheds leaves due to low temperature, we need to deal with it properly.
Will bougainvillea die when it sheds leaves in winter?
If your temperature in winter is above zero and below ten degrees, in this case, you just need to move the whole bougainvillea to a place with sufficient light,剪掉 its thin and weak branches, cut the long branches short, and if there are large wounds, apply fungicide or healing agent. Keep the soil moist by watering when it is half-dry, and it can safely pass the winter. In the spring, it will quickly sprout, and when sprouting, supplement with potassium dihydrogen phosphate, then it can bloom. If it sheds leaves due to temperatures below zero, the entire plant will die, and there's nothing you can do but discard it.
3. Root Rot leading to Leaf Shedding
Many people at home water their bougainvillea very frequently. When they don't notice the root suffocation in the early stage and keep watering even when there are few leaves left, it will eventually lead to root rot. If the branches still have green and have not completely dried out, but only the roots are rotting, we should remove the original soil, expose the roots, trim all the rotten roots clean, and soak them in carbendazim for more than half an hour.
After soaking, plant it in a small pot with well-ventilated soil, water it with a mixture of carbendazim and root-promoting solution, cover the whole pot with a plastic bag, support the plastic bag with a few sticks around the pot, make some holes in the plastic bag, and place it in a position with diffused light and good ventilation to recover for about a month. Its roots will gradually grow, and as long as the roots grow, it will quickly sprout. Gradually remove the plastic bag and expose it to more light to recover growth.
