How do I care for dahlias?


Our Advice:

Dahlias require regular watering and fertilization to produce healthy growth and blooms. Water deeply once or twice a week, and fertilise every 4-6 weeks with a balanced fertiliser. Stake the plants when they are young to support their growth and prevent them from toppling over.
