How to Grow Rocket in the UK

Rocket is a quick way to add peppery leaves to meals, even from a pot beside the door. Annual salad rocket gives fast pickings and needs repeat sowings, while perennial wild rocket grows more slowly and can keep producing for much longer. Choose the type you want, keep it watered and pick a little from several plants.

February and March sowing is under protection; April to early September is the main outdoor window. The planting band includes autumn planting under cover. April to November harvests combine early protected starts, outdoor crops and autumn shelter, rather than one continuous batch. The protected band also covers established winter plants, which may yield a few leaves in mild conditions but cannot promise rapid regrowth in the darkest months.

Is rocket right for your garden?

Rocket fits a small bed, windowbox or patio container and is easy to mix with other salad crops. A short fresh row at regular intervals is more useful than a large annual sowing that all flowers at once.

Choose salad rocket for speed and generally softer leaves. Choose wild rocket for a longer lived plant with a stronger flavour, allowing it more space as it matures. Wild in the seed name describes the crop type; you can grow it from labelled seed.

Where to grow rocket

Use a sunny position in spring and again as days cool in late summer. During hot weather, a lightly shaded spot can help salad rocket stay leafy for longer.

Rake a weed free seedbed with a fine surface. Mature compost improves moisture retention in light soil; avoid a patch that repeatedly dries out while seedlings are emerging.

Include rocket with brassicas when planning rotations and garden hygiene. A small salad crop is still related to cabbages and radishes and can share some of their pests and diseases.

For pots, use peat-free multipurpose compost and drainage holes. A container at least 30cm wide is easier to keep evenly moist than a tiny pot, especially on a sunny balcony.

How to plant rocket

Both direct sowing and modules work. Start only as much annual salad rocket as you can pick while it is tender, then make the next sowing before the first batch finishes.

1.

Select salad rocket or wild rocket and label the seed tray or row. Leaf shape alone is not a reliable way to distinguish every variety once plants are mixed together.

2.

Sow outdoors from April when the ground is workable, or start an earlier February or March batch in a bright protected place. Follow the packet for a particular selection.

3.

Make shallow drills up to 1cm deep, about 15cm apart, and water the base if dry. Scatter seed thinly, cover lightly and firm gently.

4.

Alternatively, sow into modules of moist seed compost. Keep them in good light and move seedlings on before they become crowded or dry out repeatedly.

5.

Thin established outdoor seedlings to about 15cm apart for repeated picking. Give vigorous wild rocket or module clumps more room if the supplier recommends it.

6.

Harden off plants raised under cover before moving them outside. Plant modules with minimal root disturbance, then water them in thoroughly.

7.

Protect new crops from slugs and use fine insect mesh where flea beetles are troublesome. Secure the edges while leaving enough space for the foliage to grow.

8.

Repeat small sowings of annual salad rocket every two to three weeks. Keep notes on which sowing times last longest in your garden, particularly through hot weather.

How to care for rocket

Watering

Keep the root zone moist during germination and active growth. Dry soil can encourage salad rocket to bolt, shortening the useful leaf harvest.

Check pots frequently in warm weather and move them into light shade during a heatwave if practical. Water steadily rather than letting plants wilt repeatedly and then flooding the compost.

Feeding

A short salad crop in reasonably fertile soil usually needs little extra feed. Weed competition, dryness and crowding are more useful first checks when growth slows.

Longer lived wild rocket and repeated container crops can exhaust limited compost. Use a suitable general feed at its label rate if needed, and renew tired container compost between crops.

Pruning

Pick a few outer leaves from several plants, leaving their centres intact. Taking every leaf from one plant slows recovery; spread the harvest across the row.

Annual salad rocket is usually best replaced once flowering takes over. Wild rocket can continue making edible leaves after flowering; trim sprawling growth to encourage fresh shoots rather than assuming the whole perennial plant is finished.

Winter care

Sow a late summer batch early enough to establish before short days and cold weather. A greenhouse, polytunnel or cloche can extend picking, particularly from wild rocket.

Ventilate protected crops when conditions allow and reduce watering to match slower growth. Pick sparingly in winter: protection reduces weather damage but does not restore summer light or summer growth rates.

What does rocket look like?

Salad rocket generally has broader, softer leaves and pale cream flowers with dark veins. Wild rocket usually has narrower, deeply divided leaves and yellow flowers, although leaf shapes vary with age and cultivar.

Both make four-petalled flowers typical of their plant family. Grow culinary rocket from a labelled source; this guide does not identify roadside plants for eating or imply that every plant with rocket in its common name is the same crop.

Growing rocket around the UK

Spring and late summer are especially useful for annual salad rocket. Hot spells can bring rapid flowering even in an otherwise healthy row, so use shade, consistent water and replacement sowings together.

In cool northern or exposed gardens, wait for suitable outdoor conditions and use modules or early protection if helpful. A sheltered southern patio may begin earlier, but hot containers also dry much faster.

Begin with small young leaves and taste as you pick; flavour strengthens with age and often with heat. Harvest shortly before use, rinse away soil and inspect the leaves, including any folded areas where insects may shelter.

Common problems with rocket

Common problems

Annual salad rocket bolts readily in heat, dry soil or crowded conditions. Sow smaller batches, provide light summer shade and keep water consistent. Replace spent annual plants instead of expecting them to crop like perennial wild rocket.

Flea beetles often cause small shot holes. Use fine insect mesh on fresh sowings and keep plants growing steadily. Light damage is cosmetic; badly damaged seedlings may need replacing.

Slugs and snails can remove young plants quickly. Inspect in damp evenings and protect the vulnerable crop. Raising a few plants in modules can help them reach planting size before exposure to the bed.

Older foliage, warm weather and stress can intensify flavour. Pick younger leaves, water consistently and use a newer sowing of salad rocket if the current plants no longer suit your salads.

Check for saturated compost, crowding, poor light and stale humid air. Ventilate, remove decaying material and adjust watering to the weather. A winter crop should not be watered as though it were growing rapidly in midsummer.

Seed is the simplest way to start both main types. For annual salad rocket, repeat sowing is also the most useful way to maintain quality; perennial wild rocket does not need replacing after every flowering cycle.

For seed saving, keep healthy true-to-type plants and avoid choosing the first stressed bolters. Separate varieties within the same species while flowering. Collect drying seed pods before they shatter, finish drying under cover and store the cleaned seed cool and dry.

Check salad or wild on the label

The crop type matters as much as the name. Choose annual salad rocket for quick repeated batches or wild rocket for longer production, then compare leaf shape and flavour. Buy enough seed for several small sowings rather than using it all at once.

Wildlife and pollinators

Wildlife and pollinators

Rocket flowers can attract visiting insects, and the flowers of correctly identified culinary plants are edible too. Keep a few deliberate flowering plants if wanted while replacing the annual crop intended for tender leaves.

Fine mesh protects young leaves without needing a routine spray programme. Keep it secure, check beneath it and support garden predators with suitable habitat elsewhere around the growing area.

Rocket FAQs

What is the difference between salad and wild rocket?

Salad rocket is an annual Eruca crop that grows quickly and flowers readily in heat. Wild rocket is Diplotaxis tenuifolia, a perennial with generally narrower leaves, a stronger flavour and a longer harvesting life.

Salad rocket often provides small leaves in four to six weeks under good conditions. Wild rocket can be slower. Start gently once plants have enough leaves to keep growing after picking.

Heat, dry soil and crowding encourage annual salad rocket to bolt. Provide some summer shade, thin seedlings, water steadily and sow fresh batches. Removing flowers cannot make an annual plant last indefinitely.

Usually, if you leave the growing centre and enough healthy foliage. Take a few leaves from several plants. Wild rocket can continue after flowering, while annual salad rocket normally needs replacing when it bolts.

Established plants may give limited pickings under a cloche, in a greenhouse or in a polytunnel. Sow in late summer, ventilate and avoid overwatering. Regrowth will be much slower in short, cold days.

Small holes are usually cosmetic. Inspect and wash otherwise healthy leaves before use. Protect the next sowing with fine mesh if damage is heavy, especially while seedlings are small.

Find local growers and nurseries

Rocket works best as a regular small harvest. Keep annual sowings coming, give wild plants time to establish and adjust light, water and picking to the season for tender leaves with the flavour you enjoy.
