2) Sowing the seed too deeply. Seeds should only be covered with approximately 1/8" of soil.

After sowing, seal the container in a polythene bag and place on the bottom shelf of a fridge for 3 weeks. Check regularly to monitor germination. Then, move to an optimum temperature of about 15C (59F), keeping the surface of the compost moist but not waterlogged.
