Rocket

Rocket is probably the easiest herb to grow from seed, and its peppery leaves offer just the right kind of tang for spring and summer salads.

This zesty herb originates from the Mediterranean regions. Not surprisingly, it is used as a fresh topping for pizzas and open sandwiches or for tossing through pasta before serving. Like basil, it makes a rather tasty pesto for flavouring pasta, soups and baked or roasted vegetables. Older, spicier leaves can be added to stir-fries, egg dishes, soups and stews.

Kirchhoffs has two types of rocket available in seed packets: wild rocket (Diplotaxis tenuifolia) and garden rocket (Eruca sativa).

Wild rocket has narrow, deeply lobed aromatic leaves and a stronger flavour than normal rocket. It is favoured by chefs as a microgreen or baby leaf and when used in salad should be tossed with a vinegar or citrus-based dressing to balance its flavour.

It can be sown all year round in mild climates and is slower growing than garden rocket, with a garden height of 20cm. The yellow flowers are edible and can be used to garnish salads and to decorate drinks.

Garden rocket can grow up to 60cm, with larger, softer green leaves. Like wild rocket, it can be sown thickly and treated as a cutand-come-again salad leaf. It does better as a cool-season crop because the flavour of the leaves gets stronger as summer progresses and if it flowers. Rather remove flowering stems.

How To Grow It

Both rocket varieties like rich, well-composted, friable soil and plenty of water. Sow directly or into containers, in full sun or semi shade. It is a good companion crop for green beans, dill, lettuce, nasturtiums and thyme.

Sow in spring for summer greens, and in autumn for winter greens. For a longer harvest, sow a small quantity at a time, and then succession sow every 2 – 3 weeks.

Water regularly and feed weekly. Harvest constantly and cut down 2 – 3 times during the season.

How To Use It

Rocket leaves are best used as soon as possible after picking but they can be kept in the refrigerator for a day or two if the leaves are rinsed in cool water, dried on paper towels and stored in a zip-lock bag.

Did you know?

Rocket is generally regarded as ‘just’ a culinary herb, but its leaves contain iron, vitamin C and beta carotene, as well as phytochemicals that are reputed to cleanse the body of pollutants.
