Onions need plenty of water to produce decent sized bulbs, particularly when these start to form in November and December. Onions will happily grow in pots and containers providing they have a soil depth of at least 20cm and a rich, moist vegetable mix to grow in. Garden centres sell a good supply of onion seedlings throughout spring and summer. Thin rows so plants are about 10cm apart. Transplant seedlings once they are big enough to handle without causing too much damage. The new seedlings will look like grass and are very delicate. Sow seed directly into the ground, or into trays. Onions can be sown in autumn, however won't be ready until the following summer, and will need protecting over winter in very cold areas.
