How does bougainvillea stop growing in summer? (Why does bougainvillea stop growing in summer?)

What should I do if bougainvillea stops growing in summer?

First, the growth phase is stagnant

In summer, bougainvillea is also a relatively vigorous growth period. If it stops growing, it will stop growing unless it encounters very high temperatures and strong sunlight. In this case, the bougainvillea will stop growing at this stage, or it can be called "semi-dormant".

During this period, the activity of the bougainvillea's cells decreases, and the growth stage stagnates as a self-protection measure . Because the growth of young branches not only consumes nutrients, but also greatly reduces the ability to resist heat. Therefore, a "semi-dormant period" occurs during the growth stage.

【Processing method】

   Move the bougainvillea to a cooler and more ventilated environment, or cover it with a shade net to avoid strong sunlight at noon. Remove some of the long branches and old leaves appropriately. The bougainvillea will sprout again soon and enter a period of vigorous growth .

Second, the reasons of water and fertilizer

Bougainvillea absorbs nutrients mainly through the fibrous roots of the root system absorbing water. The water carries nutrients into the body of the bougainvillea and then produces absorbed nutrients through photosynthesis, thereby promoting the growth of the bougainvillea.

When caring for the bougainvillea, we recommend that you do not fertilize it in summer. In addition, the temperature in summer is high and the water retention time in the flower soil is short. Then the bougainvillea will not be able to absorb nutrients and supply its own growth needs, resulting in no growth.

【Solution】

   In the summer, when the temperature in the place where you are caring for bougainvillea does not exceed 35 degrees Celsius, you can apply some thin fertilizer and water to the bougainvillea. Water the flower soil immediately when it is dry or wet, and spray the leaves to replenish water every day.

Generally, if you apply thin fertilizer frequently and increase the amount of water appropriately, the bougainvillea will resume its growth soon .

Third, the supply and demand balance of roots and branches

The environment is suitable and the water and fertilizer management is in place. Bougainvillea will still stop growing in summer. After the bougainvillea finishes blooming before summer, it will begin to resume the growth of branches and leaves and stop reproductive growth .

When the branches and leaves grow to a certain number and maturity, the absorption of the roots and the consumption of the branches and leaves are in a state of supply and demand balance. The bougainvillea will stop growing.

【Measures】

   The first step is to prune the branches of the bougainvillea, prune some useless branches, branches that have grown too long, including axillary branches, dense branches and other branches that affect the shape, reduce nutrient consumption, and break the balance of supply and demand. Then apply some thin organic fertilizer, and the bougainvillea will soon enter the growth period .
