Water
Deep and consistent watering, especially during dry spells and fruit development. Water the base of the plant.
Soil
Rich, fertile, well-drained soil, pH 6.0–7.0. A heavy feeder, so amend generously with compost or manure.
Spacing

Indoors

Care and harvest
Feeding
Feed with a balanced liquid feed every 2 weeks once fruits begin to form, switching to a high-potash feed later.
Pruning
For optimal fruit size and ripening in the UK, limit fruits to 3-5 per plant. Pinch out the growing tips of vines after the last desired fruit has set.
Harvesting
Allow vines room to spread; cure mature fruit before storing.
Storage
Store in a cool, dry place (10-15°C) for several months, often into winter. Do not store in the fridge.
