Seeding matrix of rock Peony

Rock peony doesn't like humus. It can be prepared by mixing gravel and medium grained vermiculite with a little rice husk ash and base fertilizer in proportion. The substrate shall be strictly sterilized at high temperature. It is best to put some large particles at the bottom when laying the matrix to facilitate ventilation and drainage. The thickness of the matrix is about 6 or 7 cm. The substrate shall be strictly sterilized at high temperature.

Sowing method of rock Peony

Sowing should have a certain plant spacing and row spacing, generally about 1 cm between each grain. The seeds are directly soaked in water on the substrate, and then covered with heat preservation

Seedling management of rock Peony

At the stage from the emergence of rock peony to the two-year period, the appropriate temperature is about 35 ℃ in the daytime and about 20 ℃ at night. Generally, the seedlings can be covered with large plastic bags for stuffy cultivation to effectively control the temperature and humidity. It is better to put them on the balcony and other places to scatter light, and it is better to form a layer of water droplets in the bag. There is no need to apply fertilizer to keep the basin soil moist. The basin immersion method can be adopted. Pay attention to the use of clean well water or tap water placed. The water depth is about half of the depth of the basin soil. It can be taken out when the surface of the basin soil begins to be wet. It must be noted that at this stage, it is best not to transplant seedlings easily

Peony rock in two to four years. Move the pot between May and June around the second anniversary. After coming out of the pot, properly prune the roots, remove fibrous roots and unhealthy roots, and sprinkle some rooting powder. Cool the seedlings for about 3 days. Add more base fertilizer to the substrate, and then keep the basin on the tidal soil, and control the seedling spacing. After one week of scattered light, soak in the basin without stuffy cultivation. Fertilizer and water can be applied after normal watering for 3 or 4 times. Appropriate amount of fertilizer can be applied according to specific conditions, and the principle of thin fertilizer and frequent application can be adhered to.
