Knowing when and how to harvest rocket is essential to enjoy its fresh, vibrant taste and maximise your yield.
Quick Answer
Harvest rocket when leaves are 10-15 cm long, typically 4-6 weeks after sowing. Pick individual leaves as needed to encourage continued growth.
Understanding When to Harvest Rocket
Rocket, also known as arugula, is a fast-growing leafy green that thrives in the UK's cool climate. In Staffordshire and the Midlands, you can start sowing rocket from March through September. The key to harvesting rocket is catching the leaves at the right size for the best flavour.
Ideal Leaf Size
For the best taste and texture, aim to harvest rocket leaves when they are between 10 to 15 cm in length. At this stage, the leaves are tender and have a delightful peppery kick without being overly bitter.
Timing Your Harvest
Typically, rocket can be harvested around 4-6 weeks after sowing, depending on the weather and growing conditions. In Staffordshire, early spring and late summer provide ideal conditions for rocket, with cooler temperatures promoting steady growth.
How to Harvest Rocket
Harvesting rocket is straightforward, but there are some techniques to ensure you get the most from your plants.
Picking Individual Leaves
The best way to harvest rocket is by picking individual leaves as you need them. This method encourages the plant to keep producing new leaves, extending your harvest period.
- Use sharp scissors or snips to cut leaves to avoid damaging the plant.
- Harvest in the morning when leaves are turgid and full of moisture.
- Regular harvesting encourages bushier growth.
Full Plant Harvest
If you prefer to harvest the entire plant, cut it back to about 2.5 cm above the soil level. This can encourage a second flush of leaves, though they may be smaller and more pungent.

Frequently Asked Questions
Can rocket be grown indoors?
Yes, rocket can be grown indoors on a sunny windowsill. Ensure it receives enough light and keep the soil moist but not waterlogged.
What should I do if my rocket bolts?
If rocket bolts, it means it's gone to seed. You can still use the smaller leaves, but they may taste more bitter. Consider sowing new seeds for a fresh crop.
How do I store harvested rocket?
Store rocket in the fridge, wrapped in a damp cloth or sealed in a container with a lid. It will keep fresh for up to a week.
