Ageratum has strong planting adaptability and can survive from low altitude to high altitude areas up to 2800 meters. The best growing areas are warm and humid low altitude areas. Ageratum is sensitive to cold, and for self-protection, it will stop growing in environments below 5 ℃ in winter. Sunlight exposure can make Ageratum grow better, and at least 6 hours of light per day can maximize its ornamental value. A soil with a pH of 6.0-7.5 can enable Ageratum to efficiently absorb nutrients, while loose and fertile sandy soil is better. Good drainage can prevent root rot.

During the growth period, water twice a day (once every 3-5 days in winter). Apply diluted fertilizer every 10-15 days. Ageratum has strong branching ability, regularly plucking and topping 3-4 times to promote branching and maintain a compact and beautiful plant shape. Every spring, replanting, soil replacement, and root restoration can be carried out to promote plant regeneration and growth. When discovering pests and diseases, spray pesticides in a timely manner for treatment. Ageratum can be propagated through sowing and cutting. Sow seeds in greenhouses or plant branches in open fields according to climatic conditions. Cutting can be done in all growing seasons except for winter. Choose robust branches, keep 2-4 true leaves, cut and insert as needed, it takes about 10 days to root.
