Care for bougainvillea during its flowering period

Differences in flowering period between north and south

Flowering time

Due to temperature differences between the north and the south, the flowering time of bougainvillea is slightly different. The flowering time in the south (Guangzhou, Hainan, Kunming) is between winter and spring, while in the northern greenhouse (indoor) it blooms from March to July.

Flowering time

The flowering time varies under different maintenance environments. Ensure 10 to 12 hours of sunshine per day, strong light and good ventilation conditions, the flowering period can reach 180 to 200 days. However, if there is insufficient light or the temperature is not suitable, it is very common for the flowering period to be 1 to 3 months.

Flowering management tips

The sunshine should be long and the light should be strong

Potted bougainvillea can bloom all year round if the main conditions of light, temperature, water and fertilizer are met. It needs 10-12 hours of sunshine a day, strong light and good ventilation. The flowering period can last up to 6-7 months, starting in mid-June and ending in December or early January. The flowering period can last up to 180-200 days. Among them, the purple bougainvillea can bloom until the Spring Festival. After people go out of the house on Qingming Festival, the flowers will bloom again on May Day.

Hypertrophy, water content

If you want Bougainvillea to bloom more and have a longer flowering period, it will consume more nutrients, and since the soil in the pot is limited, you need to add fertilizer regularly.

When repotting in spring, apply sufficient base fertilizer. Depending on the size of the pot, apply 10-15 grams of decomposed dry chicken manure or cake fertilizer per pot. After moving outdoors, apply quick-acting nitrogen fertilizer as a topdressing.

During the peak growth period, apply decomposed cake fertilizer and water every 7 days to accelerate the differentiation of flower buds. During the peak flowering period in autumn, apply alum fertilizer water every 3-5 days, spray 0.3% potassium dihydrogen phosphate every 7 days. From August to October, apply more fertilizer and water, use fertilizer instead of water, and use alum fertilizer water or fertilizer water for watering.

Scientific Management

Pay attention to the combination of watering, light control and heavy watering. In the early summer growing season, water once a day to ensure the growth of branches and leaves. From June to July, control water 3-4 times according to different varieties to make the branches and leaves wilt slightly. Spray water on the leaves 1-2 times a day, and water them thoroughly after 2-3 days. Repeat this process several times or water them every other day to promote the differentiation of flower buds.

When flower buds appear on new shoots, water them heavily once in the morning and evening every day, spray water on the leaves 1-2 times a day, and water appropriately after October depending on the dryness and wetness of the soil. After bringing the plant indoors in winter, do not water it until it is dry, and water it thoroughly when you do.
