Fill the modular tray with seed compost, pressing it down firmly to remove any air pockets. Water well and leave to drain.
Empty the contents of the seed packet into your palm and use the tip of a biro to place two or three seeds on the surface of each modular cell.
Cover the seeds with a fine layer or sieved compost - use the bottom of a plant pot to sieve the soil if you don't have a soil sieve.
Leave the tray in a warm, well lit position. If you're sowing in spring, the plugs should be ready to plant out in eight to 10 weeks. If sowing in autumn, keep the plugs in an unheated greenhouse or cold frame over winter, and plant out in spring.
