Rocket, also known as arugula, is a popular choice for many gardeners due to its peppery flavour and versatility in the kitchen. In this article, I'll share the best times to sow and plant rocket in the UK, along with some practical tips to ensure a bountiful harvest.
Quick Answer
The best time to plant rocket in the UK is from April to September. Sowing every two to three weeks ensures a continuous supply.
Understanding the UK Climate for Rocket
Rocket grows well in the UK climate, especially in regions like Staffordshire. This leafy green thrives in cooler temperatures, making the British spring and early autumn ideal for planting. The temperate climate helps prevent rocket from bolting, which is when the plant flowers and becomes less palatable.
Optimal Sowing Times
The best months to sow rocket are between April and September. Starting your planting in April allows you to take advantage of the warming soil. If you're in the Midlands, like me, the soil usually reaches an ideal temperature by mid-April.
| Month | Action | Notes |
|---|---|---|
| April | Sow seeds | Begin sowing outdoors |
| May | Sow seeds | Continue sowing for succession |
| June | Sow seeds | Ideal for continuous growth |
| July | Sow seeds | Watch for dry weather |
| August | Sow seeds | Last chance for summer sowing |
| September | Sow seeds | Final sowing of the year |
Planting Techniques for Successful Growth
When planting rocket, focus on soil preparation. Rocket prefers well-drained soil rich in organic matter. we recommend adding compost to your soil before sowing.
- Choose a sunny or partially shaded spot.
- Space seeds about 15cm apart for optimal growth.
- Water regularly, especially during dry spells.
Succession Planting
To ensure a continuous supply of fresh rocket, practice succession planting. This involves sowing seeds every two to three weeks. It’s a method I often use in my own garden in Staffordshire to keep the harvest coming throughout the growing season.
Dealing with Common Issues
Rocket is generally hardy, but you may encounter some issues like flea beetles and bolting. Flea beetles can be deterred by using row covers or planting companion plants like garlic. To prevent bolting, ensure consistent watering and avoid overly warm planting periods.
Frequently Asked Questions
Can I grow rocket indoors?
Yes, rocket can be grown indoors in pots or containers. Ensure it receives plenty of light, ideally a south-facing window, and keep the soil moist but not waterlogged.
How do I know when my rocket is ready to harvest?
Rocket leaves can be harvested when they are about 7-10cm long. Harvesting regularly encourages new growth, providing a continuous supply.
What can I do if my rocket plants bolt?
If your rocket bolts, the leaves may become bitter. You can use them in cooked dishes where the flavour will mellow, or remove the plant and re-sow for a sweeter crop.
