How to grow rocket leaves from seed

Overview

Rocket is best sown between March and September but even late sowings can produce a good crop of spicy, peppery leaves for salads. Keep nipping off the rocket leaves and it will provide rich pickings for weeks, and ensure a continual supply by making successive sowings throughout spring and summer. 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.


How to do it

Marking sowing line

1

Use a line to mark out the row. Sowing in a straight line allows you to identify where your rocket seedlings are and which are the weed seedlings to pick off. You'll find a row 1m - 2m long is enough to get you started, so long as you plan further sowings in a few weeks.


Handful of rocket seed

2

There are always plenty of seeds in a packet - usually enough to sow a row up to 6m long. But that would give you a glut all at once, so sow just a small quantity at one time, then sow regularly (known as successional sowing), to harvest over a longer period.


Sowing a pinch of rocket seed along the row

3

Carefully sow the rocket seeds thinly along the row, spacing them out as evenly as possible. The distance between the seeds should be about 3cm.


Using the hoe to cover rocket seed with soil

4

Use the edge of a hoe or a trowel to cover the seed lightly with soil. Remove any weed remnants or large stones as you go to ensure the plants have a good start.


Watering rocket seeds

5

Water the seeds in well using a watering can with the rose attached. This means you drench the soil but minimise disturbance to the seeds.


Adam's tip

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.

My rocket plants have been plagued by snails. Apart from wondering whether I could actually eat the snails I have found there, what can I do? I have put down slug pellets but it made no difference. Also, some have now gone to seed. Can I cultivate the seeds from the pods?

I've been trying to grow rocket indoors but I started 6 weeks ago and still have no rocket. They seem to thrive as seedlings but then they die off gradually after about 4 weeks. All my other plants are doing great but I don't know why the rocket is doing so badly. I don't know if other people have this problem or if you have any suggestions to stop it from happening next time?

surround your plants with a barrier of sand. The snails will not pass.
