Tips & Advice:
Sowing Outdoors
Rake soil to provide a firm, even surface. Sow seeds thinly in pre-watered soil in full sun, 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.
Thinning
When large enough to handle, thin seedlings to allow their development and prevent overcrowding.
Advice
Late summer and autumn sown seedlings may benefit from cloche or fleece protection when hard frosts threaten. Such plants generally bloom earlier the following summer than spring sown plants.
