In SA it is quite common for people to grow vegetables in old tyres. This would also work really well with potatoes because you can just tip them over and harvest the potatoes very easily. I know this article say you shouldn't, but has anyone tried?

I would be grateful if anyone could advise me as to a late planting variety of potatoe available in S.A. It appears that the variety favoured in the USA is Butte. Any advice would be most welcome

As from 2010 I have been planting potato seedlings in my backyard garden what I noticed is that they do not flower for pollination to take place but when I harvested them I got big quality tubers. The following year I planted the potato seeding in winter and they thrived well but the same thing of not flowering happened again and the harvest was good. This is surprising me really ,. What could be the reason for these potato plant not flowering but able to form tubers.

Hi Can potatoes be planted in a tunnel or does it need bees for polination?

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
