Onions are easy to grow from baby onions, which are called sets. While you can buy seeds, sets are less prone to disease and more likely to provide good crops in poorer soils.

Onions can be planted from February to early April, but organic matter or fertiliser should be added to the soil at least one month before planting. Add a bucket of garden compost or well-rotted manure for every square metre and add 35g of fertiliser.

Make a hole about 2cm deep in the soil and plant the onion sets around 10cm apart in rows about 30cm apart.

Gently push the sets into the soil so the tips are just showing. Make sure they are the right way up with the roots at the bottom, and then firm the soil around them.

Remember to label each row of onions.
