Choose pots that are a little larger than the disc, then fill them up with seed compost. Firm and level the surface and place a seed disc on top.
Cover the seed disc with a fine layer of vermiculite, which is easier to spread thinly, alternatively you could use seed compost if you prefer.
Water the pot thoroughly, cover with cling film, and stand it in a warm, bright position. When seedlings emerge, remove the cling film.
Pot seedlings on as they grow, keeping them watered so that the compost doesn't dry out. Give them a liquid feed once a week.
Once they are large enough to handle, transfer individual seedlings to smaller pots. Handle by a leaf to avoid crushing the stem.
Pinching out the tip of your plants will encourage bushy growth. Keep on watering them and they can be planted outside in summer.
