When to sow: Feb – May
Spacing: 30 x 20cm
French Marigold tips: Sow indoors with heat (21°C) from Feb, under cover from March, and outdoors from May.
In modules cover the seeds with a very fine layer of compost which must be kept moist – a mister works well for this.
If sowing outdoors sow 0.5cm deep in drills 30cm apart, and thin to final spacing.
