Unwins Zinnia Benary's Giant Seeds

Almost fill a seed tray with moist seed compost. Sow seeds 5mm deep and lightly cover with a little more compost. Place in the warmth, 15-20°C and keep moist.

Keep seedlings in a light position but shade from direct sunlight. When large enough to handle, transplant into trays of potting compost.

Gradually accustom plants to outside conditions for 2-3 weeks before planting out from early summer onwards. Allow 25cm between plants.

Seed can be sown outdoors when soil is warm. Sow thinly and lightly cover with a little soil. Keep soil moist until seedlings emerge. Thin to 25cm apart and transfer thinnings to other parts of your garden.

Water regularly, especially during warm, dry spells and feed using a liquid plant food. Deadhead regularly to prolong the flowering period.
