Sweet potatoes are becoming increasingly popular and are well worth trying outdoors in milder areas. In colder areas they make excellent crops for a glasshouse or polytunnel. This nutritious vegetable is so versatile - boil, bake, mash or fry them!Spread: up to 3m (9')
Please note: We supply 'slips' (cuttings) which are despatched by first class post in our special boxes and must be opened immediately. 'Slips' will look withered on arrival, but just place them in a glass of water overnight. Pot them up individually ensuring the length of the stem to the base of the leaves is covered (use our ‘Sweet Potato Potting On Kit’).
Pot up sweet potato slips and grow them on in warm, frost free conditions for 3 weeks or more until they are established. When all risk of frost has passed, gradually acclimatise plants to outdoor conditions prior to transplanting them into the planters provided using a good compost. Sweet potatoes require high temperatures of 24–26C (74-78F). When growing sweet potato in cold areas they are best grown in a greenhouse or polytunnel. Water generously after planting.
Water sweet potato plants regularly Spread the stems out around the plant and cut back to the growing tips to encourage more lateral stems to develop. Harvest sweet potatoes in late summer approximately 12 to 16 weeks after planting, when the foliage begins to turn yellow and die back.
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.
