The real advantage in growing Dahlias from seed is that you get the best of both worlds. The first year will provide a very economical collection of bright flowers and each plant will produce tubers that can be carefully lifted at the end of the end of the season for storing and re-planting the following year.

Cactus Mixed produces large double blooms formed with slender pointed petals. This variety makes a lovely garden display and a superb cut flower because of its vibrant colour and its overall growing height of 90-120cm.

When to Sow Cactus Mixed Dahlias

February to April.

Where to Sow

Sow the seeds in trays of moist seed compost and cover with a fine sprinkling of compost or vermiculite. Place in a warm place and keep at a temperature of between 20-25°C (68-77°F).

What to do Next

When the seedlings are large enough to handle, prick off into trays 5cm apart. As seedlings grow, transplant into 9cm pots and gradually harden off before planting out in the flowering site from late May onwards. Space plants 60cm apart.

Maturity

July onwards.

Height

90-120cm (36-48″)

Handy Tip

Reducing the amount of flower buds per stem will increase the size and quality of the blooms produced.
