🌱 Sowing: In Trays vs. Direct in the Ground

Rocket is one of those delightfully unfussy crops that does best when direct sown into the soil, but there are a few good reasons to start it in trays too.

Direct Sowing

Direct sowing is the most common and often the easiest method for rocket. Because it germinates quickly and grows fast, it’s perfectly suited to being sown straight where it’s meant to grow. Just scratch a shallow furrow (around 5mm deep), water it in well, and thin the seedlings as they grow.

It’s a great crop to tuck in between slower growers like brassicas, tomatoes, or zucchini to make the most of your space.

Tray Sowing

Rocket can also be started in trays, especially if you’re managing slugs, snails, or birds, or if your soil is still warming up at the tail-end of winter. Start them in biodegradable pots or plug trays so you can transplant without disturbing the roots. Harden off seedlings before planting them out.

🚿 Tip: Rocket seedlings don’t like to be disturbed too much—so if you’re transplanting, do it young and gently.

❄️ Seed Pre-Treatment

Rocket seeds don’t require any special pre-treatment. Just sow them fresh and they’ll spring into action quickly—often within 3–7 days if soil temperatures are warm enough (10–25°C is ideal for germination).

---

🌞 Soil & Position

Rocket likes a sunny to part-shaded position. In hotter regions, partial shade can help reduce bolting and bitterness—especially in late spring and summer.

Choose a free-draining soil, ideally enriched with compost or aged manure. Rocket doesn’t need overly rich soil, but it will appreciate some organic matter for a steady nutrient supply.

Soil pH

Rocket prefers a neutral to slightly alkaline soil (pH 6.5 to 7.5), but it’s quite adaptable.

🛠️ Care & Maintenance

Rocket is quick, easy, and forgiving, but it still benefits from a little regular care:

• Watering: Keep soil moist, especially in warmer weather. Dry conditions will lead to tougher leaves and faster bolting.
• Feeding: Not usually necessary in rich soil, but you can top-dress with a light compost mulch if needed.
• Thinning: Thin seedlings to 10–15cm apart for leafy growth or leave them closer (5cm) for baby leaves.

🧺 Keep harvesting often—this helps prolong the leafy growth phase and delay flowering.

🧑‍🌾 Companion Planting Guide

Rocket is part of the brassica family, so it plays nicely with most garden companions, but a few partnerships really shine.

Best Companions:

• Carrots & Beetroot: These root crops grow slowly and don’t mind rocket’s fast pace.
• Lettuce: Shares similar care needs and creates a lush salad patch.
• Herbs like dill and mint: May help deter pests like aphids and flea beetles.

Avoid:

• Other brassicas in the same bed: Rotate rocket out of beds used for cabbages, broccoli, or kale to prevent soil-borne diseases.
• Strawberries: They can compete for nutrients and space.

✂️ Harvesting Rocket

Rocket grows quickly—baby leaves are ready in 3–4 weeks, and full-sized plants in 5–6 weeks.

How to Harvest:

• Pick outer leaves first for a cut-and-come-again harvest.
• For a big bowlful, harvest whole rosettes with scissors at the base.
• Don’t wait too long—older leaves can become bitter and tough.

Flowering:

If your rocket starts to flower (bolting), the leaves become more pungent. You can still eat them, but consider letting a few plants go to seed for saving.

🐛 Common Issues & Fixes

Problem	Symptoms	Likely Cause	Fix
Flea beetles	Tiny holes in leaves	Warm, dry conditions attract these brassica pests	Use insect netting or companion plant with dill. Keep soil moist.
Bolting	Plants send up flower stems early	Too much heat or stress	Provide shade, consistent watering, and sow during cooler months.
Slugs/snails	Chewed leaves or missing seedlings	Damp conditions	Use crushed eggshells, copper tape, or beer traps. Seedlings can be started in trays.
Powdery mildew	White powder on leaves	Humid or overcrowded conditions	Improve air flow and water early in the day. Remove affected leaves.

🌸 Seed Saving Guide

Saving seed from rocket is super easy and a great way to keep your garden going season after season.

Step-by-step:

1. Let a few plants bolt and flower. You’ll get lovely creamy-white flowers with dark veining that are also edible and pollinator-friendly!
2. After flowering, long seed pods (siliques) will form.
3. Allow pods to dry fully on the plant—they’ll turn brown and brittle.
4. Harvest pods before they shatter, especially in windy weather.
5. Place pods in a paper bag and leave to dry another week or two.
6. Crush and winnow to separate seeds from the chaff.
7. Store seeds in a cool, dry place in an envelope or jar, clearly labelled.

🧂 Seed viability: Rocket seeds remain viable for 3–5 years if stored well.

🌼 Final Thoughts

Rocket is the kind of crop that keeps on giving—it grows fast, doesn’t need much fuss, and rewards you with punchy, fresh leaves that elevate any meal. Whether you’re sneaking it into a salad mix, wilting it over pizza, or tossing it through pasta, you’ll be glad you gave it space in your patch.

Best of all, its short growth cycle makes it perfect for succession sowing—every few weeks, tuck in a few more seeds to enjoy rocket year-round in milder climates.
