How do I overwinter dahlias in a cold climate?

Dahlias in cold climates must be overwintered in a frost-free place by removing the tubers from the ground. Dig up the tubers after the first frost, when the foliage has died back. Let the tubers dry for a few days and carefully remove loose soil. Store them in a cool, dry, and frost-free place (for example, in peat, sawdust, or newspaper).

How long do dahlias usually bloom?

Dahlias bloom for a long time, usually from July until the first frost. Regularly removing spent flowers encourages new blooms. Sufficient sun, water, and nutrients extend the flowering period. Some varieties bloom almost continuously until well into autumn.

How tall can dahlias grow?

The height of dahlias varies greatly depending on the species and variety. Dwarf and border dahlias remain compact (about 30-50 cm). Medium-tall varieties are suitable for borders and pots. Large dahlias can grow to 1.5 meters or taller and often require support.

How much sun do dahlias need?

Dahlias need plenty of sun to bloom profusely and for a long time. They grow best in a location with at least 6-8 hours of direct sunlight per day. Too little sun results in drooping stems and fewer flowers. Some varieties can tolerate light afternoon sun, but full sun produces the best blooms.
