Rocket has spicy, peppery leaves, ideal for pepping up salads. It is best sown between March and September but even later sowings can produce a good crop of spicy, peppery leaves for salads.
Find out how to make a salad mix.
Harvest the young leaves as you need them and you will enjoy rich pickings for weeks. Sow every two weeks throughout spring and summer for a continuous supply. As autumn approaches, cover crops with sheets of horticultural fleece to keep the cold at bay, and you could be cropping right through to first frosts.
You can also sow rocket in pots – again, sow every two weeks so that you have a continuous harvest.
Remove flower stalks to prolong leaf production, unless you want to eat the flowers and seed pods too – both are edible.
Flea beetle can be a problem in summer, nibbling holes in rocket leaves. The best defence is to cover the row with a length of horticultural fleece or a fleece-covered mini tunnel.
