Zinnia Cactus Flowered Mixed

When to Sow Zinnia Cactus Flowered Seeds

March to May

Where to sow

Sow Zinnia seeds into individual pots or module trays of moist seed compost and cover with a very fine sprinkling of compost or vermiculite. Place in a propagator or a warm place at a temperature of between 20-23°C (68-75°F). Do not exclude light as this helps germination which usually takes 7-14 days. Later sowings can be made outdoors once the soil has warmed up 3mm (1/8") deep in drills 30cm (12") apart, in well cultivated weed free soil. When large enough to handle, thin out seedlings to 30cm (12") apart.

What to do next

When well grown gradually acclimatise young plants to outdoor conditions for a few weeks before planting out after all risk of frost 23-30cm (9-12") apart, taking care not to damage the root system. Best planted in well drained soil in full sun.

Handy Tip

A sheltered but sunny position is best. The flowers have long stems and are long lasting as a cut flower.
