Setup, Compatibility & Care
Sowing Outdoors:
- Timing: Sow seeds outdoors in April to May, after the last frost.
- Preparation: Prepare the ground by weeding and breaking it down to a fine tilth. Ensure the soil is free-draining.
- Sowing Depth: Sow seeds 3mm deep.
- Spacing: Sow in rows that are 30cm apart.
- Watering: Water the soil gently after sowing.
Sowing for Pot Plants (Spring/Summer Flowering):
- Timing: Sow in late summer or early autumn.
- Location: Use a cool greenhouse or conservatory.
- Growing Conditions: Grow on in cool conditions with full light.
- Watering: Water sparingly.
Aftercare (Once Seedlings Appear):
- Thinning: Once seedlings are large enough to handle, thin them to 15cm apart.
- Location: Position the established plants in full sun for best flowering.
- Soil: Thrives in free-draining soil.
Compatibility:
- Compatible with most garden soils, provided they are well-draining.
- Ideal for mixed borders, rockeries, and container plantings.
Care:
- Regular watering is needed, especially during dry spells, but avoid waterlogged conditions.
- Deadheading spent flowers can encourage further blooming.
- Annual plant; typically does not require overwintering, replant from seed each year.
