FAQs

When is the best time to sow these seeds?

Sow from late winter to spring for the best results.

Do I need to cover the seeds with soil?

No, sow them on the surface of the compost as light is beneficial for germination.

How far apart should I plant them?

Space them 30cm (12in) apart to ensure they have enough room to reach their 40cm spread.

Can I grow these in semi-shade?

Yes, they perform well in full sun or semi-shade.

How long does germination usually take?

Germination typically takes between 7 to 20 days under the correct temperature conditions.

Are these plants perennial?

No, they are summer-flowering annuals and will complete their life cycle in one season.

Troubleshooting

Seeds failing to germinate

Ensure the temperature is maintained between 21-24C and that the seeds are not covered, as they require light to germinate.

Seedlings becoming 'leggy'

Move plants to a cooler location with more access to natural light once they have germinated.

Plants wilting after planting out

Ensure they were properly hardened off over a 10-15 day period and that the soil remains well-drained.

Setup, Compatibility & Care

To begin, sow seeds on the surface of good, free-draining seed compost from late winter to spring. Keep the compost moist but not saturated, and place the container in a sealed polythene bag to maintain humidity. Keep the temperature between 21-24C and ensure the seeds have access to light, as this is essential for germination. Once seedlings are large enough to handle, transplant them into individual pots and grow them in cooler conditions. Acclimatize the plants gradually over 10-15 days before moving them to a permanent sunny or semi-shaded location once the frost risk has completely passed.
