Plastic basins are lighter, warmer, cheaper, and lighter, but have poorer air permeability. Due to the rapid growth season, it is beneficial to promote root growth and promote tree development. Both pots have their advantages and disadvantages. Plastic pots are preferred. Pot diameter should not be less than 50cm, pot height 30cm is appropriate.
1.3 The choice of matrix
Soft-seed hawthorns prefer neutral soils, loose-breathable, well-drained soils with high organic matter content. The base is prepared with a ratio of 10:3 to 4 by using peat soil or mountain bark and decomposed farmyard manure. The tested pH is 6.5-7.0.
2 Hawthorn Potted Plant Main Techniques and Requirements

Soft-seed hawthorns are fond of water and drought-resistant. In soil with good permeability, soil moisture content of not less than 30% can be. In early spring from March to April, each fruit tree is used for special fertilizer (compound fertilizer) 20 to 30g. In the autumn (August-September), 20-30g of special fertilizer for fruit trees will be applied again.

For example, concentrated shoots or other nearby pest-carrying trees require prevention and control of borers. Control time Sprayed deltamethrin 800 times before 7 to 10 days before flowering, spraying the whole tree. 7 to 10 days after flowering can be sprayed once. The soft-seed hawthorn has strong anti-fungal diseases without the need to control other leaf diseases.
2.5 winter protection
