How to grow dahlias

1. Dahlias have large fleshy roots and grow in loose, fertile soil with good air permeability and drainage. In the cultivation process, the soil must be loosened frequently to prevent it from becoming compacted and water from stagnating. Otherwise, it will easily lead to root rot, and in severe cases, the dahlia will die.

2. Dahlia is a light-loving plant. It is not shade-tolerant. It must be placed in a sunny environment during normal cultivation. Insufficient sunlight will slow down its growth and affect its flowering period. During the cultivation period, dahlias should be fertilized appropriately. After entering the peak growth season, they have a relatively large demand for fertilizers. They should be top-dressed every 10 to 15 days. Be sure to choose a thin liquid fertilizer. If the fertilizer concentration is too high, the dahlia will burn its roots and easily die.
