🌿 How to grow successfully

🤝 Companion planting

Allow room for sprawling vines; flowers nearby may help attract pollinating insects.

↔️ What to avoid

Avoid cold wet soil, overcrowding and watering directly over foliage.

🐛 Pests and diseases

Powdery mildew, aphids, slugs and mites.

🧤 Ongoing care

Mulch well and water at soil level without wetting leaves.

🧺 Harvest and storage

Harvest firm, glossy fruit regularly; refrigerate for short periods and avoid chilling for extended storage.

🧑‍🌾 From sowing to harvest

Prepare the soil

Work compost into a sunny bed and leave ample room for vigorous roots and vines.

Sow or transplant

Sow in warm soil after frost or start indoors shortly before transplanting; avoid disturbing roots.

What to monitor

Look for powdery mildew, aphids, poor pollination and drought stress during fruit swelling.

When and how to harvest
