Potatoes need potassium (also called potash). Further, potatoes need potassium at the VERY BEGINNING of their growth cycle -- that is, for some reason potato plants uptake all (or MOST) or their potassium at the VERY beginning of tuber formation. If at the very beginning of tuber formation (probably barely visible to the human eye) -- anyhow, if there is not enough potassium you WILL impact tuber growth. At a minimum you will have HOLLOW HEART -- which is potatoes with an empty middle -- the potato sort of grows like a balloon being blown up -- and the tuber will take from the middle to reinforce the outside walls -- that is why the smaller potatoes will not have hollow heart, but the larger potatoes will -- THAT IS TO SAY: potassium supply will impact not only SIZE of the potatoes but the density.

If you grow determinate potato they only grown on one level. There is absolutely no need or reason to keep piling up as the plant grows. Indeterminate potato will grow multi level but also no need to pile up. Not when container grown anyway. There is a gentleman that knows a ton on growing and constantly had tested different things. He has a great playlist on YT and his channel is simplify gardening. He is in Wales UK but really knows his stuff. Also knowing what potatos are early, second early variety helps as to when to get them started etc.

Probably too much N fertiliser. It is not about growing a tall plant. It is about growing a plant that produces a crop. A good amount of general fert before planting and hill the soil up around the pant when about 12 inches

It is because it takes 3 months for Potash to become available in the soil. You always have to plan ahead when you are using Potash or, no matter how much you put on your tater plants they won't be able to access it.

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

I just read about Determinate and Indeterminate potatoes. Which varieties of Indeterminate potatoes do well in Zone 10A?

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.
