Sowing Instructions
| Sowing time: | late May to July. |
|---|
Sow at 20-30C (68-86F) on the surface of a good free-draining damp seed compost.
Apply a very fine sprinkling of compost or vermiculite, 3mm (1/8in) thick.
Place in a propagator or seal container inside a polythene bag until after germination which usually takes 16-22 days.
Do not exclude light at any stage as this is beneficial to germination.
Growing Instructions
Transplant when large enough to handle into 7.5cm (3in) pots and overwinter in a cool greenhouse or on a windowsill, giving an optimum temperature of around 7C (45F).
Plant out the following Spring, 1m (3ft) apart in a well drained soil in full sun.
Aftercare Instructions
Protect plants with a layer of bracken over the winter months.
