What do hibiscus flowers usually need to do for maintenance?

Hibiscus Hibiscus, which we usually call Hibiscus Hibiscus, is a native plant in China, native to Sichuan, Guangdong and Yunnan. The temperature in these places is relatively high, so hibiscus mutabilis naturally likes warm environment, and it will freeze to death at MINUS 10 degrees. Because of this feature, the cultivation in the north and the south is different. In the south, it is usually planted in the ground, and in the north, it can only be potted. Because it is a native tree species in China, it is easy to adapt to the environment in the usual maintenance process. But open-air cultivation is slightly different from potted plants. My hometown is in the south, and hibiscus can often be seen in the surrounding communities and streets.

Open-air cultivation: watering: open-air cultivation is suitable for spring. First, base fertilizer is applied to the planting hole, and then sufficient irrigation is carried out after planting. After sprouting and growing leaves, water them properly according to the wet and dry conditions of the soil.

Fertilizer: no need to supplement fertilizer for two to three years after planting.

Pruning: In the first few years of planting, in order to overwinter safely, it is necessary to cut it properly and cultivate the soil at the base to make it overwinter better. Pruning can promote more lateral branches, just like an old saying: old ones don't go, new ones don't come, and pruning can increase the number of flowers. In the next few years, just comb off the sick leaves and old leaves.

Pot: flowerpot: because hibiscus mutabilis is relatively high, you should choose a big wooden pot for potted plants.

Soil: Garden soil and compost soil are selected and mixed according to the ratio of 7:3.

Daylighting: It is in line with his nature to put it in a sunny place.

Fertilization: usually water him and loosen the soil, that is, in the rainy season, topdressing liquid fertilizer, mainly phosphorus and potassium fertilizer, is helpful to flower bud differentiation, which blooms during 8- 10, and each flower blooms for 10 days, and then dies.

Pruning: Leave 4-6 strong buds after germination, and pick the rest. When the plant grows to about 30 cm, start cutting branches and leaves, leaving only 2-3 leaves at the base, which can promote branching. After the flowers wither, cut off the branches 5-8 cm from the soil surface and put them indoors for the winter.

Change pots: the temperature rises after winter. Before moving outdoors, we should replace the flowerpots and soil, add some new culture soil and replant the original flowerpots.
