Why Sow in June?

• Extended Season: Take advantage of warm soils and daylight to push crops later into the year.
• Succession Opportunity: Fill gaps left by early spring sowings and avoid lull periods.
• Optimised Space: Intercrop quick-growers with slower-maturing plants for maximum productivity.

Quick-Growing Salad Leaves & Greens

• Rocket & Mizuna: Germinates in 5–7 days; sow in shallow drills, thin to 5 cm.
• Baby Leaf Mixes: Ready in 3–4 weeks; perfect for containers or interrows.
• Mustard & Leaf Chicory: Sow every 10–14 days for a continuous cut-and-come-again harvest.

Second-Wave Root Crops

• Radishes (Cherry Belle, French Breakfast): Germinate in 4–5 days; harvest in 4 weeks.
• Baby Carrots (‘Paris Market’): 7–10 days to germinate; thin to 5 cm for tender roots in 6–8 weeks.
• Beetroot (Golden, Cylindra): Germinate in 7–14 days; thin to 10 cm for mid-summer pulls.

Heat-Loving Fruit Vegetables

• Courgettes & Summer Squash: Germinate in 5–8 days; plant 2–3 cm deep, 60 cm apart.
• Cucumbers: Sow in pots/modules under cover; transplant when true leaves appear.
• Sweetcorn: Sow in blocks of four for pollination, 2 cm deep, 30 cm apart; succession sow mid-June.

Legumes for Succession Cropping

• French & Runner Beans: Sow when soil ≥12 °C; bush beans 5 cm deep, 5 cm apart; runners 10–15 cm apart with supports.
• Peas (Mangetout, Sugar Snap): Sow early June for late summer pods; 5 cm deep, 5 cm apart in rows.

Herbs & Edible Flowers

• Basil & Coriander: Germinate in 7–14 days; succession sow every 3 weeks for fresh cuttings.
• Nasturtiums: Sow directly 2–3 cm deep to deter pests and add peppery petals to salads.
• Borage: Self-seeds prolifically; sow in gaps for pollinator appeal and edible flowers.

Cover Crops for Soil Health

• Buckwheat & Phacelia: Sow quick-growing green manures to suppress weeds and improve soil structure before autumn digging.

Succession Sowing Strategies

• Staggered Drills: Divide bed into sections; sow quick crops every 10–14 days.
• Intercropping: Plant fast salad leaves between slower courgettes or brassicas.
• Container Rotation: Clear spent pots and reseed with baby leaf mixes or radishes.

Site Preparation & Soil Tips

• Light Cultivation: Fork or rototill to 15–20 cm, removing weeds and debris.
• Soil Amendment: Incorporate 3–5 cm well-rotted compost for moisture retention.
• pH & Drainage: Aim for pH 6.0–7.0; improve heavy soils with grit or sand.

Sowing Methods & Depths

Aftercare: Watering, Feeding & Pest Control

• Watering: Keep newly sown beds evenly moist with fine sprays; transition to deeper, less frequent waterings once established.
• Feeding: Side-dress fruiting crops (courgettes, beans) with balanced feed every 2–3 weeks; avoid over-fertilising salad crops.
• Pest Monitoring: Use slug pellets or collars around brassicas, netting for peas and beans, and hand-pick slugs at dusk.

Conclusion

Sowing vegetables in June unlocks a new wave of fresh produce—salads, roots, fruiting veg, and legumes—while enabling succession sowing for a continuous harvest. By preparing your soil, using targeted sowing depths, and employing succession strategies, you’ll bridge the mid-season gap and enjoy a surge of homegrown bounty from summer into autumn.

   Yes—French and runner beans sown in early June produce pods from mid-summer.
3. How deep should I sow courgette seeds?
   2–3 cm deep, either direct or in modules, with 60 cm spacing.
4. What root vegetables work best for June sowings?
   Radishes (4 weeks) and beetroot (8–12 weeks) thrive when sown in June.
5. When should I water new June sowings?

   Sow every 10–14 days in shallow drills for continuous harvest.
7. Which herbs are suitable for June sowing?
   Basil, coriander, and nasturtiums flourish in warm June soils.
8. Do I need to fertilise salads and roots?
   Minimal feeding—light side-dressing for root vegetables; avoid fertiliser on greens.
9. How can I protect peas and beans from slugs?
   Use netting, collars, or organic slug pellets to safeguard seedlings.
10. What cover crops should I sow in June?
    Buckwheat and phacelia quickly build organic matter and suppress weeds before autumn.
