Sow seeds in seed compost in a seed tray or in modules. Place in a heated propagator and keep around 15-20°C unless the seed packet instructions differ. Once germinated, remove cover to increase ventilation. When large enough to handle, carefully transplant seedlings into modules or small pots and grow on in the greenhouse or on a well-lit windowsill. Keep compost just moist, and six weeks from sowing, feed fortnightly with a liquid fertiliser, such as tomato food, Phostrogen or Miracle-Gro. If seedlings become leggy, pinch out shoot tips to encourage branching. Harden off (acclimatise to outdoor conditions – see March blog for further details) and plant outdoors once risk of frost has passed.
