Once plants start emerging use as a drip tray under the tray and grow on in a good strong light place,

When plants are ready plant out into a deep, rich well composted and moist soil. Make 15cm deep holes with a garden stake and place the seedling into the hole. Don’t close the hole with soil .  Instead, water the plant which will close the hole with the right amount of soil.

Watering of the young plants is vital until they are well established and weeding is just as essential.
