How to care for bougainvillea during its off-flowering period

First, prune after the flowers wither

After the bougainvillea flowers fall, many flower stalks will be left in the branches. These flower stalks will take a long time to dry up and fall off naturally. However, during this stage, nutrients and water will continue to be consumed, so timely pruning is required.

According to the shape of the bougainvillea, trim off the flower stalks and the long and thin branches to reduce nutrient consumption.

When pruning, prune some adventitious buds that grow at the same time as the flowering stage, as well as some taboo branches of bonsai , such as inner branches, dense branches, dull branches, etc. For the long branches, do appropriate shortening to promote the growth of side buds.

Second, fertilization

After bougainvillea blooms, it consumes a huge amount of nutrients, and we reduce the supplement of "nitrogen" elements when promoting flowering.

When applying fertilizer, first use "urea" which mainly contains nitrogen to quickly replenish the "nitrogen" element, which is conducive to quickly resuming the growth of branches and leaves and promoting the growth of side buds. Urea is used for fertilization in the early stage, and it is applied twice, with an interval of about 15 days between each application.

About 20 days after applying urea twice, you can use organic fertilizer containing the comprehensive elements "nitrogen, phosphorus and potassium" to supplement the elements.

"Phosphorus and potassium" can promote rooting and photosynthesis, and play a good role in the rejuvenation of bougainvillea. Phosphorus and potassium can promote flowering, so try to use nitrogen in the first two fertilizations during the flowering period, and then use organic fertilizers with comprehensive nutrients.

Third, watering method

During the flowering period of bougainvillea, we will properly control the water. Excessive watering will accelerate the metabolism of bougainvillea and affect the flowering effect of bougainvillea. During the resting period, you can return to the daily watering management method.

It mainly depends on the dryness and wetness of the soil, and you should "not water if it is not dry, but water thoroughly if you do ." At this time, you don't need to let the flower soil dry out before watering. When the shallow surface soil is about 3 to 5 centimeters dry and moisture-free, you can water it thoroughly.

Fourth, topping and pinching

During the off-flowering period, the bougainvillea is pruned and fertilized with plenty of water, and new buds of the bougainvillea will grow out immediately.

When the tree grows to about 10 cm and has two leaves, you can top the new branches and keep two buds. Do this to allow new buds to appear again. This will allow multiple buds to grow on the side branches in a short period of time. The growth of side buds can prevent new branches from growing too long and form a compact crown.
