Seeds sown indoors allow earlier flowering and cropping. The protected environment is also easy to manipulate for specific requirements

Many containers are available. Small seeds are generally sown in a shallow tray and pricked out into larger pots. Slightly larger seeds can be sown into individual modules if space allows, limiting transplant shock. Large seeds can be sown individually into 9cm (3.5in) pots. Old containers should be thoroughly cleaned before use.

Compost

Use a standard soil-based or soil-less seed composts for indoor sowings. These are finely milled and contain few nutrients, which could otherwise damage seedlings.

Method

Many seeds require specific sowing treatments, such as light-exclusion and scarification (scratching or nicking the seed coat), so check seed packets for specific instructions. Fill the container with compost, level, firm gently and water well. Sow seeds thinly. Very small seeds can be mixed with fine sand before sowing to obtain more even distribution. Sift a fine layer of compost or vermiculite over the seeds. Label, lightly water again and either cover with clear polythene and maintain a temperature of 18ºC or place in a heated propagator.

Check daily for emergence. Once seedlings emerge increase ventilation and remove covers. Keep the compost just moist and, unless sown individually, prick out seedlings at the first true leaf stage. Gradually harden-off plants before placing them outside.
