More tender crops like aubergines and courgettes, still need to be sown under glass, either in a greenhouse or on a sunny windowsill.

You can also plant out potatoes, as well as onions sets, shallots and garlic and Jerusalem artichokes.

Find out which crops you can sow in April, below.


Aubergines, chillies and tomatoes

This is the last chance to sow aubergines, chillies and tomatoes, which need a long growing season to do well. If you only want a few plants, you could wait until next month and buy plants at the garden centre. Find out how to grow aubergines, chillies and tomatoes.

Beetroot

Beetroot is an easy crop to grow, making it ideal for beginners. It will grow in any fertile, well drained soil and also does well in containers. Follow the spacing on the packet and thin the seedlings to about 10cm when they are around 3cm high. Harvest when the beets have reached golf ball size.

Carrots

Sow carrots on well-prepared soil that is free of stones – stony soil results in forked carrots. At this time of year, it is a good idea to protect against carrot fly, by putting up a barrier around the crop. Discover 10 ways to deter carrot fly. Your crop should be ready to harvest three to four months after sowing.

Peas

Peas are easy to grow and can be harvested early in summer, making them a welcome early crop. You can sow them direct outside, but they are a favourite snack for mice – if these are a problem, sow them indoors and plant the plants outside when they are 15cm tall. Alternatively, sow in guttering and transplant the whole row of seedlings into a trench when they’re ready.

Radish

This fast-growing crop is easy to grow and is a good ‘catch crop’, growing on empty ground that is waiting for other crops, or between slower growing crops. Sow direct outside, every three to four weeks, for a continuous supply throughout summer. Watch our video guide to growing radishes.
