Frequently Asked Questions

What does fully double mean for the blooms in this dahlia mix?

The flowers have multiple overlapping layers of petals that create a dense rounded form without a visible open centre typical of single dahlias

Do plants grown from these seeds form tubers for future seasons?

Many will develop small tubers by the end of the first year that can be lifted and stored in colder climates for replanting the following spring

Is staking necessary for the taller plants in the mix?

Stems reaching 2–4 feet often benefit from support especially in windy spots to keep the heavy double blooms upright and undamaged

How well do the double blooms perform as cut flowers?

The strong stems and long-lasting fully double heads make them excellent for arrangements holding their colour and form well indoors

Can the tubers be overwintered successfully outside hardiness zones 8–11?

In cooler regions the tubers should be dug after foliage dies back and stored dry in a frost-free place until spring planting

Does pinching the young plants encourage a bushier shape?

Removing the growing tip early on promotes branching which helps produce more flower stems and a fuller upright bushy display
