Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically every 4-6 weeks, to support its vigorous growth.植え替え
Repot Caucasian comfrey every 2-3 years or when it outgrows its container. Choose a slightly larger pot with good drainage, and refresh the soil to provide new nutrients. Repotting is best done in early spring before the growing season begins.伝搬
