Japanese water Iris is commonly used for division and sowing propagation. Branches are usually carried out in early spring in March or after flowering shoots. The mother plant is dug up, the rhizome is divided, and two or three buds are planted respectively. Sow, and the seeds will be ready for sowing by the end of August. The seedlings emerged 4-6 weeks after sowing, and the seedlings bloomed 2 years after cultivation.
1. Division propagation: Division propagation always carries out in spring, autumn. When dividing Japanese water Iris, dig the mother plants with roots, split plants from tillering,and we can take 1-2 stem or side branches, lower part with roots, plant in wet soil respectively, then water after planting.
Preparation of peat: Perlite: the matrix of the loam was 7:1:4, and the loam was crushed and sifted, and all were exposed to the sun. When sowing, lay a substrate of about 20cm on the bottom of the container, and evenly spread the dew seeds on it. Then cover the fine loam, gently press it flat, and place it in a pool of 10cm deep, allowing it to absorb water naturally and slowly, so as to moisten the soil.With this method, the seedling rate can reach 95%.
After harvesting, the Japanese water iris seeds should be purified, soaked in 0.5% potassium permanganate solution for 10-20 minutes, washed with clean water, planted in the wooden box containing sand, placed indoors, about 20 days later, spread in the foot water. Bed surface level, soft seedbeds are covered with fine soil 1-2 cm, and in the next spring, it can sprout.
