Sowing Instructions: Sow at any time of the year.  Sow in pots at a depth of 4mm into a free draining damp seed compost, seal in a polythene bag or place in a propagator and maintain at about 21C. Keep the compost moist, but not over wet. Germination can take anywhere from 7 days to 3 months.

If any seeds still haven’t germinated after 3 months, transfer the container in its bag to the fridge for a further 3 months, then return the container to 21C and germination should occur.

Growing Instructions: When seedlings are large enough to handle, pot up individually into 7.5cm pots and grow on in slightly cooler conditions, repotting as necessary.

For hardy species, plant out in late spring after hardening off the plants by placing them outside during the day for a week and keep well watered until established.  For tender species, pot up in their containers using a free draining houseplant compost and place in a well lit, sunny spot away from draughts and keep well watered.
