How to grow Organic Rocket from seed

We find it best to sow rocket seeds in a line, usually along a border or fixed boundary to help us remember where they are. Otherwise use plant markers or interplant with some fast growing radish seeds as a good visual reference. Thin weeds out untill established.

Sow direct every 3cms along your line and gently cover with soil or alternatively sow in any of our larger thick walled coco pots to keep near the kitchen for easy and quick harvesting.

Repeat sowings every two weeks throught the spring and summer to enjoy a continuous supply of peppery leaves. Cover with horticultural fleece towards the end of the season to extend your harvest through to the first frosts.



What to feed your organic rocket plants

Organic Rocket seeds should be planted in firm fertile soil. Amend the area before transplanting with a good mix of rotten farmyard manure, fish, blood and bone meal with some volcanic rock dust and kelp powder to give them a rich, balanced and diverse diet that will be released over the season for strong organic growth.

Stronger, healthier plants are also less attractive to attacking insects.

Keeping pests away

Rocket can be affected by flea beetles which you can physically exclude through the use of horticultural fleece or mini hoop covers. These tiny shiny black insects (like most garden nasties) are particularly attracted to weak, nutrient stressed and underwatered plants.

This is why we advocate regenerative and organic methods of growing, building the soil and the availability of nutrients far beyond any NPK chemical fertilizer, whilst boosting the plants natural immunity as a result.

When ordering Early Sprouting Purple Broccoli seeds from Grow Sow Greener, you will receive free marigold seeds lose in your pack. A beautiful plant in its own right, plant marigolds close by to deter nematodes and attract beneficial insects that prey on pests while boosting pollination for your other fruit and veg.
