Watering. About 1 inch a week; consistent moisture raises yield even though established vines tolerate dry spells.

Feeding

Seedlings
Plant into soil enriched with well-rotted compost; seedlings need little extra feed.
Growing
Side-dress with 2-4 inches of well-rotted compost in midsummer, kept away from the stems.
Flowering and fruiting
Drench with a liquid organic fertilizer once plants begin to flower heavily.
How often
At planting, then twice during the season: compost at planting and midsummer, and one liquid feed at heavy bloom.
Note
Go light: excess fertilizer can rot the tubers.
