Management Methods and Care Tips for Bougainvillea After the Flowers Fade

In autumn and winter, when flowers and plants are in their declining season, the bougainvillea, which is quite popular in southern regions, also gradually moves from its growing season into dormancy. Whether grown in the south or the north, several things need to be done after the bougainvillea flowers fade, otherwise the flowering quality of the coming year will be directly affected. Let's take a look together with the editor below.

1. Pruning

Pruning bougainvillea mainly serves two purposes: one is to control the plant's shape and prevent it from becoming messy, and the other is to stimulate new growth and development, helping it transition from the reproductive stage to the growth stage. Its pruning is also fairly flexible, with no strict requirements, because bougainvillea grows vigorously, so even heavy pruning at the right time will not kill it; when pruning, you can cut freely according to your own preferences. Pruning generally addresses three aspects. First, remove the unhealthy branches of the bougainvillea, which increases the plant's air circulation while also saving nutrients. Second, promptly remove leggy branches; bougainvillea is very prone to leggy growth in autumn, and when leggy branches grow to a certain extent, they should be pinched back in time so they do not rob nutrients from the other branches. Third, appropriately shorten and prune branches that have already flowered to stimulate new bud growth.

2. Fertilizing

Bougainvillea has a long flowering period and a large number of blooms, consuming a lot of nutrients during flowering, so it should be fertilized promptly after flowering to help it recover as quickly as possible and strengthen its resistance to cope with the external environment. If it is not fertilized after flowering, its new buds will sprout more slowly and fewer in number, the plant's resistance will be poor, and it will be highly prone to disease. After the bougainvillea finishes flowering, dig open the surrounding potting soil and bury in some decomposed organic fertilizer to let it recover slowly. If there is no organic fertilizer, you can also apply some nitrogen-phosphorus-potassium compound fertilizer.

3. A Suitable Environment

After the flowers fade, the bougainvillea should also be kept in sufficient light, especially since its flowering period falls in autumn and winter, when light is relatively weak, so it must be placed in a sunny spot to fully absorb sunlight and grow more robustly. After the flowers fade, keep the environment warm; the suitable growing temperature for bougainvillea is between 15-25 degrees, and after the flowers fade in winter, warm measures need to be taken. You can place it in a warm, sunny spot indoors, which can effectively prevent the plant from freezing damage and help it overwinter safely.

4. Watering

Bougainvillea also needs moderate watering after the flowers fade, but at this time the plant's water requirement is not very high; generally watering once about every 5 days is enough. Just keep the soil slightly moist, and never allow waterlogging to occur. In addition, the water temperature should be close to the soil temperature, so as to avoid a sudden drop in soil temperature that could harm the plant.
