How to Sow Tomato Seeds
Unless you want to grow masses of tomatoes, sow the seeds into small 3 in (7.5cm) pots. If space is short choose square pots as they fit more easily into limited space than round pots. Alternatively use modules that allow each seedling to develop a good root system separately from its neighbour, this removes the need for pricking out and makes potting seedlings up much easier for you and better for your plants.
Sow greenhouse tomatoes from January for an early crop. Outdoor tomatoes should be sown in April and May so that they are the correct size for planting out after the last frosts.

Fill pots and modules to the top with a fresh batch of quality seed compost. Choose Westland John Innes Seed Sowing Compost or if you want to grow organically choose Earth Matters Peat Free Multi-Purpose Compost. Firm the compost gently so that it is about 12mm (1/2in) below the rim of the pot.
Water the compost with tepid water and allow to drain.
Make a series of shallow holes using a dibber and sow the seeds into these. As a rough guide you can sow 3 or 4 per pot. Cover over with a light layer of finely crumbled compost or a thin layer of vermiculite.
Label well and place into a heated propagator at 18-20C (65-70F). Check daily and water sparingly when required.
