Eruca vesicaria subsp. sativa

vegetable

verifiedReviewed by the GreenScout Team

Rocket is a fast-growing leafy green vegetable known for its peppery, slightly spicy flavor. The tender leaves can be harvested within 3–4 weeks of sowing and are popular in salads and as a culinary garnish. This cool-season crop prefers mild temperatures and can bolt quickly in heat, so succession planting ensures continuous harvests.

Care Guide

light_mode

Light

Full sun to partial shade; 6–8 hours of direct light daily. Light afternoon shade helps prevent bolting in warm climates.

Water

Keep soil consistently moist but not waterlogged. Water regularly, especially during dry spells, providing 1–1.5 inches per week. Reduce watering slightly in cooler months.

compost

Soil

Well-draining, fertile soil rich in organic matter. Aim for pH 6.0–7.0. Rocket tolerates poor soil but yields better leaves with compost or aged manure incorporated.

science

Fertiliser

Moderate feeder. Apply balanced fertilizer (10-10-10) every 3–4 weeks, or use compost mulch. Excessive nitrogen promotes leaf growth but may reduce peppery flavor.

thermometer

Temperature

Thrives in cool to moderate temperatures of 50–70°F (10–21°C). Grows well in spring and fall; heat triggers bolting. Can tolerate light frosts.

Frequently Asked Questions

How soon can I harvest Rocket?

The tender leaves can be harvested within 3–4 weeks of sowing — it's one of the fastest salad greens, and succession planting every couple of weeks ensures continuous harvests before it bolts in heat.

Why does my Rocket taste milder than store-bought?

Excessive nitrogen promotes leaf growth but may reduce the peppery flavor — lighter feeding with compost or aged manure, rather than heavy nitrogen fertilizer, preserves the characteristic spicy bite.
