Leave 2-3 strong seedlings in each hole, combined with loose soil. Weed, cultivate the soil, apply human and animal manure, apply again in June to July, and add phosphorus and potassium fertilizers appropriately.

Prune to control plant growth, peel buds to preserve flowers, remove axillary buds that have not yet formed inflorescences, and cut off vegetative branches in July to promote autumn seed maturity.
