How to manage bougainvillea after it has faded (how to prune and maintain bougainvillea after it has bloomed)

First, remove the remaining flowers and prune appropriately.

(1) Remove the remaining flowers

After the bougainvillea blooms, the flower stalks remaining on the branches turn brown, which not only affects the appearance, but also accumulates and consumes nutrients.

Once the blooming period of bougainvillea is over, you can trim off the remaining flowers and the top of the branches. You can also remove some old leaves at the same time. Prevent the consumption of nutrients by the remaining flowers, pedicels and top branches in time. Let the bougainvillea concentrate nutrients and restore the tree as soon as possible.

(2) Proper pruning

When bougainvillea blooms, the branches at the flowering part will continue to lengthen.

After the flowers bloom, many branches become too long and become disconnected. The branches are too long and deviate from the original shape. They need to be adjusted through pruning to avoid affecting the ornamental value of the overall crown.

After the bougainvillea has finished blooming, it is necessary to promptly prune off the branches that have grown too long during the flowering period, as well as some useless branches, such as: inner branches, cross branches, stuffy branches, axillary branches, etc. The purpose of pruning is also to reduce nutrient consumption and restore the tree as soon as possible.

Second, adjust the environment appropriately

When promoting the flowering of bougainvillea, in order to allow it to photosynthesize better and promote more flowering, we will maintain it in full sun.

However, sufficient light will promote the reproductive growth of Bougainvillea during the flowering period, while inhibiting its nutritional growth.

After the bougainvillea has finished blooming, we can shorten the light exposure time of the bougainvillea appropriately, according to the principle of "flowering in the sun and sprouting in the shade". Appropriately shade it or move the pot to a location where the light exposure is no longer than 6 hours.

This will make the branches and leaves of the bougainvillea more vigorous, and more buds will sprout after pruning. When repotting, also pay attention to avoid strong sunlight at noon.

Third, increase water intake

Before and during the flowering period of Bougainvillea, we will limit the water supply appropriately to promote flowering and prevent the branches and leaves from growing too long.

When it continues to bloom, we just return to daily watering, but the flowers will also increase their water consumption during this period. This is equivalent to the peak flowering period, when water is mainly supplemented for the flowers rather than the branches and leaves.

The branches and leaves are still in the "water shortage period". Therefore, after the bougainvillea blooms, it is necessary to increase the water content appropriately.

After the bougainvillea has finished blooming, the watering method should also be based on the dryness and wetness of the planting material, and "do not water if it is not dry, and water thoroughly if it is dry." However, we can replenish moisture to the bougainvillea by spraying.

Spray the leaves of bougainvillea once in the morning and evening every day until water droplets fall and wet the shallow surface soil of the planting material.

Fourth, nutrient supplement

After the bougainvillea has finished blooming, the nutrients consumed during the flowering period are huge, and the tree is relatively weak at this time. It is necessary to replenish nutrients in time for the growth of branches and leaves.

After the flowering period, pruning to reduce nutrient consumption, shortening the light hours and increasing water supplementation can effectively restore the tree's vigor. However, the most important thing is to shorten the recovery period through fertilization.

When fertilizing Bougainvillea after it blooms, it is recommended to first supplement it with elements mainly consisting of "nitrogen" to change the nutrient bias during the growth stage of Bougainvillea, because nitrogen fertilizer mainly promotes the growth of branches and leaves.

After diluting urea with water, water it on the flower soil once every half a month for two times. After two nitrogen supplements, resume using "organic fertilizer" with balanced nutrients. Use fermented chicken manure and rice husks to loosen the soil and bury them shallowly on the surface of the potting soil.
