Cover the seeds with a depth of finely sieved compost equivalent to the thickness of the seeds. Note - this is not necessary with very fine seeds such as begonias.

Water well using a fine spray but do not soak. Then cover with a clear lid.

Position the propagator in an area with plenty of light but avoid strong sunshine which can damage young seedlings.  

When the seedlings appear, you should decrease the humidity within the propagator by gradually opening the ventilator(s) on the cover(s). Once the humidity levels have dropped, you can remove the covers altogether.

Do not be afraid to ‘prick out’ the seedlings with a dibber if they are crowded together. Crowding can cause oxygen and light starvation and you will achieve better results by selecting the healthier seedlings.

When the seedlings are large enough to be handled, they should be transplanted into pots or trays, to allow them greater space to develop. Be careful only to handle young seedlings by the leaves.

The young plants will then need a further ‘hardening off’ period indoors prior to planting outside. Remember young plants are very susceptible to frost, so watch the weather!
