Water your pots well to settle the compost snugly around the roots. Firm the soil around the base of the plug gently with your fingers. Plant the plug deeply, up to the juncture of the first two true leaves and the stem. Pot up your plugs into 9cm pots using good quality peat free multi-purpose compost, handling the root ball to guide them in. Your plugs will have strong root systems, but they’re still too small to go outdoors or into a full size pot just yet. When your tomato plugs arrive, remove from the packaging as soon as possible and give them a good watering. Tomato plug plants are a great way to save time and space. Watch this video for a step-by-step guide to growing tomatoes from plug plants If you're only growing a few plants, simply sow two seeds into a couple of 7.5cm (3") pots and remove the smaller plants as they begin to grow. Protect the plants from frost, cold winds, and draughts which might kill them. Hold the plants by the leaves, taking care not to touch the stems, and transplant them into 7.5cm (3in) pots. Pot on the tomato seedlings as soon as they're big enough to handle. Tomato seeds usually germinate in 7 to 14 days if you maintain a steady temperature of 21 degrees celsius. Keep the compost moist, but be careful not to over-water as wet conditions can encourage ‘damping-off’ disease, and other mould problems. Cover with 1.5mm of compost and water lightly with a fine-rose watering can. Sprinkle the seed thinly onto good quality seed compost. Sow your tomato seeds in March or April, approximately 6-8 weeks before the final frost, or earlier if you're growing your tomatoes in a greenhouse.
