Keep the soil moist, watering in dry spells, to ensure consistent growth and prevent plants running to seed (bolting) prematurely. Give rocket some shade in hot weather, to prevent the leaves becoming tough and unpalatable. Cover with fleece or make summer sowings in a spot that gets some light shade.

Rocket typically flowers between May and August. Most rocket flowers are edible, however do check individual seed packs for confirmation. If you allow some plants to flower and produce seeds, they’ll self-sow to give you new plants without any effort. When harvesting pick a few leaves from several plants. If you take lots of leaves from one plant, growth will be weakened.
