Wheatgrass is easy to grow at home. The seeds, or wheatberries are small oval shaped and brown in colour. They can be purchased from health food shops.

Step 1. Place topsoil, preferably peat moss in plastic trays. Lay the soil in trays a couple of inches deep.

Step 2. Soak one cup of wheatberries for 24 hours then rinse. One cup of the seeds will be sufficient for a 25 x 35cm tray. Spread the seeds out so that they touch each other. Water so the soil becomes damp.

Step 3. Cover the seeds with a second tray – this will protect the germinating seeds from light and keep them warm. Leave for three days.

Step 4. Remove the tray and take outside in the sun. The grass should be a little over 2cm high.

Step 5. Harvest when 20cm tall. This takes 5 – 10 days. Cut the grass nearest to the root. The grass will keep unwashed for up to 7 days.
