1, sunny
Bougainvillea likes plenty of sunshine and belongs to a flower variety that is not afraid of sunshine in summer. Many bougainvillea in the south are cultivated in the open field and can bloom all year round. As a potted flower, it can also be kept in a sunny place, even when the sun is strongest, it does not need shading treatment. Because of the lack of sunshine, it will affect the flowering of bougainvillea.
2. Most of the soil is dry and watered.
Bougainvillea likes wet environment. By wet, we mean wet environment, not wet soil. On the contrary, bougainvillea likes dry soil. If the soil accumulates water for a long time, it will easily lead to the root rot of bougainvillea, so attention should be paid when watering.
When we water bougainvillea, we can wait until most of the soil is dry and then water it again to judge whether bougainvillea needs watering. We can judge whether the bougainvillea leaves droop sooner or later, because even after watering at noon, when the sun is too strong, the bougainvillea leaves will droop.
When the weather is dry, in addition to watering bougainvillea, water should also be sprayed around leaves and flowerpots frequently, which can not only reduce the temperature, but also make the environment of bougainvillea moist, which is beneficial to its growth and flowering. Raising bougainvillea in summer is well ventilated, especially after watering bougainvillea, to prevent the occurrence of high temperature and high humidity, resulting in bougainvillea without pests and diseases.
3. Fertilize sparingly
The flowering period of bougainvillea is relatively long, from May to 10 every year, and fertilization is needed during its growing period. Fertilize bougainvillea, instead of using raw fat fertilizer, you can use the method of thin fertilizer and diligent application.
Fertilizing bougainvillea in summer, if the temperature is higher than 35 degrees, it is necessary to stop fertilizing, because the temperature is too high, which is prone to fertilizer damage. When the temperature is lower than 35℃, apply dilute decomposed cake fertilizer water every 15 ~ 20 days, or Huaduo No.2, which can promote flowering and make bougainvillea grow stronger.
4, appropriate pruning
In summer, bougainvillea grows rapidly, so proper pruning is needed when planting bougainvillea, which can make bougainvillea plants more rounded and bloom more. When pruning bougainvillea, we need to remove the strong ones and leave the weak ones, that is, topping the branches that grow too strong or pruning them to make the weak branches grow better. There is also pruning branches that are too strong, weak and dry, which can play a role in ventilation and light transmission and reduce nutrient loss.
