Sweet Potato Trio (Treasure Island Series)Ipomoea batatas

Gradually acclimatise sweet potato plants to outdoor conditions over 7-10 days prior to planting directly outside once all risk of frost has passed. Sweet potatoes require high temperatures of 24-26°C (74-78°F). Planting them through black plastic will provide extra warmth in cooler climates. When growing sweet potato in particularly cold areas they are best grown in greenhouse borders or under cloches.

Plant sweet potatoes 30cm (12") apart, leaving 75cm (30") between rows. Grow sweet potatoes in rich fertile, light sandy well drained soil. They prefer an acid or neutral soil in full sun. Prepare the soil in early spring by adding plenty of well rotted manure or garden compost to the soil to improve its structure and fertility. Water generously after planting.

Culinary note: Culinary uses of sweet potato are similar to potatoes - boil, steam, bake, fry, mash or batter fry as 'tempura'. The leaves and tips of young shoots can be cooked as a spinach substitute.
