Growing Calendar for Sweet Potato T65 x5 slips
Delivery: Mid April to Late May
Attractive and delicious tubers; red-skinned with white flesh, variety T65 is a vigorous and reliable and well suited to growing in a cooler climate. It’s a great source of vitamins and minerals.
Crops from an attractive climbing plant with ornamental heart-shaped leaves and morning-glory flowers, so is good for decorating the vegetable plot while waiting for ample harvests.
Delivered to you as 5 ‘slips’ – young plants developed from the potato tubers, ready to form a healthy-root system once planted.
As soon as the slips arrive immerse them in a glass of water so that ¾ of the stem is submerged; leave them for up to a to a week to revive and firm up ready for potting on.
Pot them up with multi-purpose compost in individual containers covering the stems right up to the base of the leaves. Grow them on in pots for up to a month, or overwinter, in frost-free conditions, if possible in a humid environment, so they develop a strong network of roots.
Transplant into bigger container or soil (preferably in greenhouse borders) in mid-spring, once risk of frosts has passed.
Although they are tender vegetables, they are less fussy about what soil acidity they are planted in; just ensure that it’s a fertile, free-draining soil in a sunny site (21-26°C).
Harvest when leaves yellow and wither in mid- to late summer
On arrival the slips may look withered. Do NOT worry!
Lay them in a shallow bowl of cool water approx. 2cm deep so that all of the stem is just covered with water. Placing in a warm light room. Leave them in this state for at least a week until roots have started to form from the base of the stems. Add fresh water daily in order to keep the slips healthy and stop the water from turning sour.
Once the roots have developed, carefully plant the whole slip individually. Mostly fill a 9cm pot and lightly firm the compost before curling the stem around the pot and placing on compost surface, topping with compost so that the stem is covered leaving just the base of the leaves protruding. Water and keep warm. Allow the plants to establish root systems within the pots before planting on into their final container this typically takes around 3 weeks.
Sweet Potatoes require high temperatures and plenty of space to produce good yields. In the UK they are best planted in poly tunnels or greenhouses, however in a warm sheltered outdoor spot they can thrive. In order to increase the productivity of the plants try covering the beds in black polythene and planting through in order to increase temperature, or planting in black 30cm containers. Fleece and Cloches can also help.
Sweet Potatoes prefer full sun on well-draining fertile soil. Plant 30cm (12”) apart and leave at least 75cm (30”) between rows. Alternatively they can be grown in containers or patio grow bags.
Water regularly and feed every few weeks with a multi-purpose fertilizer. Sweet Potatoes are vigorous with sprawling stems that can be tied onto a trellis or strings if desired.
Approximately 12-16 weeks after planting, the foliage will start to turn yellow and die back… now it is time to start harvesting. The tubers can be left in the ground longer if you desire larger potatoes.
Ensure that all tubers are lifted before the first frosts.
Dead slips received on arrival in post.
None of the slips continued to grow.
They failed to thrive even though the water was changed daily. I drew this to Marshall Seeds' attention but they couldn't be bothered to respond.
