Although most bougainvillea flowers are diligent, letting them bloom for a long time will also make the plants consume too much nutrients, resulting in less and less flowering at flowering stage.
If bougainvillea gets a good rest in winter, then after the warm spring next year, a large number of new branches will sprout and then the buds will bloom.
When bougainvillea bougainvillea is raised in the northern region, the temperature is relatively low and the plants will enter a semi-dormant state. At this time, the maintenance should focus on rest, which can be managed according to the principle of "3 less/kloc-0 more", so that plants can have a better rest and bloom in the coming year.
Give priority to with light cutting.
After winter, bougainvillea is not suitable for large-scale pruning, especially when the environmental temperature is too low, it is more likely to make the plants have the risk of frostbite, and the new buds that germinate in the second year will be very thin, which will affect the normal flowering.
If you plan to prune bougainvillea in winter, you should also give priority to light pruning, only pruning messy branches, such as branches that grow too high and too long, thin branches below, and branches that are too dense.
Proper pruning of these thin and messy branches will help the plant survive the winter, reduce the consumption of nutrients, make it grow more stout branches in spring, and then sprout and blossom on these new branches.
Reduce the number of watering.
The bougainvillea cultivated by many flower lovers will have a large number of yellow leaves in winter, which is not only related to the climate, but also directly related to improper watering.
In winter, the temperature is low, the plant growth is blocked, and it enters a semi-dormant state, so the water demand is reduced.
In addition, the transpiration of plants is weakened and the water consumption is low. After watering once, it may not dry for several days.
If you water the pot soil like bougainvillea in the peak season, it will make the pot soil wet for a long time, and finally cause damage to the root system, so that it can not absorb water and nutrients normally, and the yellow leaves will fall off.
Therefore, in the case of low ambient temperature, water should be controlled, and the soil in the basin should not be too wet. At least wait until the pot soil is dry before watering, which is more conducive to the overwintering of plants and reduces the occurrence of freezing injury.
Apply less fertilizer in cold weather.
To raise bougainvillea in winter, we should not only control watering, but also pay attention to the harm of fertilization to plants.
Because after dormancy, it is not appropriate to use too much fertilizer, otherwise it will not be easily absorbed by plants, but will burn the roots and lead to rotten roots and yellow leaves.
Before winter, bougainvillea can be given overwintering fertilizer, such as fermented organic fertilizer, sheep manure, bean cake and so on. , or a small amount of slow-release fertilizer.
Farmer's long-term controlled-release fertilizer vat slow-release fertilizer Taobao official store bought it at 29.99. After entering winter, plants stop growing at low temperature, so there is no need to apply any fertilizer to them. After the spring is warm, it will supplement nutrients and make plants grow and bloom more.
Get more sunshine.
If families want to raise bougainvillea, they must have enough light.
Because it is a typical sunshine-loving flower, in the case of long-term insufficient light, it will cause plants to grow white, branches and leaves to grow messy, slender and not bloom.
Although winter enters a semi-dormant state, it also needs sufficient light. The more sunlight, the more nutrients can be provided for plants and their cold resistance can be enhanced. After the spring is warm, it will resume vigorous growth and open more flowers.
To raise bougainvillea in winter, as long as the above points are done well, the plants can have a good rest for a while, and when the spring is warm and the flowering branches are full of flowers, they can grow more vigorously.
