Sweet potato farmers here grow sprouts by “bedding” seed potatoes in March. This is done by placing the whole potato in the ground, covering them with a thin layer of soil and plastic. Sprouts will be cut and transplanted from the greenhouse or bedding field to a different field in May or June. It takes approximately 90-120 days without frost to grow a sweet potato. Sweet potatoes are ready to dig 90-120 days after sprouts are transplanted. Around here in August the rows are plowed and sweet potatoes are flipped on top of the ground. Most sweet potatoes are cured. Curing changes starches in the sweet potatoes into sugar, making it sweeter and the skin tougher. It takes 4-7 days of 80-85̊ temperature and 80-90% relative humidity to cure sweet potatoes. After being cured, sweet potatoes are stored at temperatures between 55-60º F and 85% relative humidity. This special storage process is why sweet potatoes are available 365 days a year here in USA. Here in North Carolina, USA sweet potatoes are shipped all over the world. It is one of our largest farmed food crops. I hope this helps... ~Melinda

Thank you - excellent information - especially about "bedding" the sweet seed potatoes and cutting the sprouts for transplant!!!

Sweet potato sprouts are known as "slips". In the United States sweet potatoes tend to be the reddish type with orange flesh, a good variety is Georgia Jet, Australia may be more familiar with what we would call yams.

It suggests you plant Mar April. You grow potatoes from potatoes not seeds.

It depends -- not all potatoes are suitable for towering (layering). Additionally, I have found that the potato plant SPENDS A LOT OF ENERGY GROWING UP, UP, UP, as you cover its leaves with soil (leaves have specialized cells designed to collect light - and why you would want to cover them with soil is beyond me this is not really a good move -- leaves are not roots). My recommendation is: if you have a DEEP PLANTER bag starting at about six inches from the bottom -- in sort of a pattern that looks like the 5 on a die (dice) -- make about 3-4 inch round holes -- and make them on the sides that receive light keeping the holes about 10 inches apart (6 inches away from the bottom and 10 inches away from the top of the bag). Fill the bag with a good soil/compost/manure mix of some kind -- starting from the bottom -- when you are level with a hole, place a seed potato there, level or slight below the bottom lip of the hole, and about 3 inches from the side of the bag (so there is soil between the potato and the hole) -- continue up until the bag is full -- the top layer of potatoes can be planted as usual. Yes, the soil will come out of the holes ... not to worry -- just be sure that the soil covers the topmost holes by at least 6-8inches. That is - each potato planted in the bag should have access to a WINDOW (air and light) OR those planted on the top layer (like a usual planting) should be down about 9 inches or so. The Key to this planting is ALL potatoes need to be able to put leaves somewhere -- they will follow the air and light to find that spot -- all potatoes need water -- so you will be watering from the top of the bag only (like a potted plant) -- but you water DEEPLY, since the water needs to make it to the very bottom potato plants -- so maybe you water every 5 days or so... depends on the soil, temperature, amount of light , amount of wind/air (which whisks moisture away), Additionally, ensure there is drainage at the bottom of the bag .... maybe a two inch hole directly at ground level. It might be better to use a crate of some kind.... rather than a bag...anyhow this set up will work with any kind of potato plant without consideration as to whether or not it can handle towering. Hope this helps. Conversion of inches to cm : 1 inch = 2.5cm
