Please Note

These seeds should ideally be sown this season. All our packets have ‘Sow by Date’ guidance on them, this is the date the seeds should be sown in order to achieve the highest rate of germination. You will still see the same high-quality plants if sowing in seasons after the ‘Sow by Date’ but may see a reduction in germination rate

Description

  • Delightful, striped, frilly flowers

  • Compact in height, but also suitable for cutting

Sowing Indoors

Level fill a tray with seed compost firming with the base of another tray. Water well with a fine rose. Scatter seeds thinly, lightly covering with vermiculite or a little more compost. Place in a propagator at 18-25°C or cover tray with cling film and leave in a warm room.

Growing On

When shoots appear, remove cling film. Keep seedlings in a light position, but shade from direct sunlight. When large enough to handle, transplant 5cm apart into small pots or module trays. Grow on in a minimum temperature of 10°C.

Planting Out

Gradually accustom plants to outside conditions for 2-3 weeks before planting out in full sun when risk of frost has passed. Allow 30cm between plants. Water well until established.

Aftercare

Water well, especially during warm spells. Feed regularly during the flowering season and deadhead faded blooms to keep plants blooming for longer.
