We are finally heading towards spring; temperatures are increasing, and the days are beginning to lengthen. A large selection of seeds can be sown this month, some of which can be sown directly into the ground.

Vegetables to be sown directly in March

Sow batches of spring onion seed about 12 mm deep in rows about 15 cm apart. Don’t sow thickly, and you won’t need to thin the onions later. They should be ready for harvesting about two months after each sowing. 

Peas can be sown directly now as long as your soil isn’t cold and wet. If in doubt, cover the area you intend to sow with a cloche.  

Potatoes can be grown in the ground or in planters. 

Other tasty greens such as winter salads, spinach, kale and cauliflower can all be sown now into Rootrainers and placed on a bright windowsill to encourage germination.

Vegetables to be sown indoors in March

Chilies and herbs (including chives, mint and coriander) can be sown into pots now and placed on a windowsill or in a greenhouse until frost has passed.

Sweet peppers still need warmth.  So if you want to plant in March, they are best started in pots and kept on a warm windowsill or a heated greenhouse.

Tomatoes can be sown now in Rootrainers and covered with a propagation lid until seedlings begin to appear. They require moist and peat-free multipurpose compost.
