Fill the seed tray or small pots with moist compost. Sow each dill seed into the compost (one or two per small pot), then sieve a little more compost over the top to cover them. Water the seeds with a fine spray. Move the container to a warm place to allow the seedlings to grow. A warm window sill or propagator is ideal.
Transplant the seedlings when they are about 2 inches high into larger pots or containers that have some loose gravel in the bottom for drainage, topped up with compost. Leave plenty of space around each seedling. The container can then be put in a sunny position in the garden. Keep it watered using a fine spray, particularly in extreme dry conditions.
Remove any weeds around the plants and keep them watered. Cut the leaves on a regular basis to encourage new growth during the summer. You can also allow the dill to go to seed and collect the seeds as soon as the flower heads are brown. The seeds should be allowed to dry off indoors before using for cooking.
