Sowing Indoors

For earlier flowering, sturdier plants, sow in trays of moist seed compost from February to April in gentle warmth 10-15C (50-60F).

Transplant 5cm (2in) apart into other trays of compost when seedlings are large enough to handle. Gradually accustom to cooler conditions before planting out from April onwards.

Sowing Outdoors

Rake soil to provide a firm, even surface. Sow seeds thinly in a pre-watered soil, lightly covering them with a little more soil.

Sowings made in semi circular lines create a natural "drift" effect. Keep moist until seedlings appear and as required in dry spells.

Growing on / thinning

When large enough to handle, thin seedlings to allow their development and to prevent overcrowding.
