Not enough water or not enough nutrients. My guess is water.

Check on google what varieties are indeterminate and then see if any in your area.

How late can you start growing potato’s? My first batch was planted March 20 but plants are already wilting back and I was wondering if I could plant more in June?

I live in Zone 10A and have been growing russet and golden potatoes in grow bags and large containers here for about three years, and I notice I can plant them year-round and they will grow, just slower in winter, and if we get an occasional frost, it may kill the top, and when temps hit around 100 or hotter the potato tops may die off also. No matter what time of year, my potatoes often grow for a few months and then the tops start to die off no matter the season or conditions, but I don't know why, so when that happens, I'll reduce the watering for a couple weeks and then harvest. I try to do "succession" planting, so I always have some potatoes growing, and am still experimenting with what works best, especially trying to learn more about correct watering for the Zone 10A conditions. I do have better success, producing more and larger potatoes, with 10-20 gallon and larger containers than the 7-gallon fabric grow bags.

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

I'm growing just a few purple potatoes in a cage following the instructions above. I've never grown potatoes before at all so need some help please. When they sprouted the little plants are not what I imagined. I thought it would be a tallish, narrow shoot but it is a little clump of leaves about 10 cm round (the clump, not each leaf). Do I just bury this whole thing in the next layer of mulch etc? I can't imagine how it will grow through. Perhaps I should have watched more closely and mounded up before the leaves opened, but I didn't notice until they were like this (the leaves are almost the same colour as the compost mix). So, is it OK to bury them now, or should I have done it sooner? I only planted four bits and the first two are as described but the other two are just coming up now, so not too late for those perhaps but they are all together.
