The form of Zhu Jin;

Red hibiscus is a deciduous shrub, 3 to 4 meters high, and its branchlets are densely stellate tomentose. Leaves rhombic to triangular-ovate, 3-lobed or undivided, obtuse at the apex, cuneate at the base, irregularly dentate at the margin, glabrous along the veins below, stellate pilose above, stipules linear and sparsely pilose.

Cultivation techniques of red hibiscus;

Before planting hibiscus flowers, the seedbed should be adjusted, and 6 kg of manure, 0.5 kg of burnt soil and 75 g of calcium, magnesium and phosphorus should be applied per square meter as base fertilizer. Cutting requires ditch depth 15cm, plant spacing of 8- 10cm, and the upper end of cutting is exposed to the soil surface for 3-5cm. After cutting, the soil is compacted and watered in time.

Cutting seedlings generally take root and sprout around 1 month. You can use insulation and heating facilities such as plastic greenhouses. Cutting seedlings can also be planted in sand beds after defoliation in autumn. At the same time, water it in time, cover it with plastic film, keep the temperature at 18 ~ 25℃, and move it to the nursery for cultivation after rooting.

When the branches of Hibiscus tomentosa begin to sprout, topdressing should be done in time, focusing on quick-acting fertilizer to promote nutritional growth, topdressing 1 ~ 2 times before sprouting to promote plant germination, topdressing twice at 5 ~ 10 flowering stage combined with weeding and soil improvement, focusing on phosphorus and potassium fertilizer.

In winter dormancy period, hibiscus flowers should be weeded and cleaned, and furrows or holes should be dug around the plants to apply fertilizer, mainly farmyard manure, supplemented by appropriate inorganic compound fertilizer to supply nutrients needed for growth and flowering in the coming year. In long-term dry and rainy weather, we should pay attention to irrigation, and when there is too much rain, we should drain water to prevent waterlogging.

The newly planted hibiscus is small, so it can grow or be lightly pruned within 1 ~ 2 years, that is, pruning dead branches, weak branches of diseases and insect pests and declining branches in autumn and winter. When the tree grows up, the hibiscus plants should be pruned, and pruning should be carried out after the leaves fall in autumn.
