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.

My potatos have come on very nicely. I just started digging them for new potatoes. Wife did some with parsley garlic and butter - delicious. Now my question is how long can I leave my potatoes in the ground after the tops dry off. We live in a Retirement Village which has lovely large veg plots. We do not have a lot of room to store spuds. Cheers Pete

If the soil is fairly dry they could keep for a couple of weeks in the soil. When you dig them up, leave in the sun or a shaded place for 1 or 2 days to toughen the skin a bit then store in a cool dark place.

Depends which ones you like and if the potatoes are picked the right time (mature) they will keep in a cool place.

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?

I live in Southern California Zone 10A and grow potatoes year-round in bags and containers, anywhere from 5 to 15 gallons size. I have found what works well for me is to put about 4-6 inches of good soil in the container, lay a few seed potatoes on top so the slips are pointed up, about 12 inches apart, then cover them with about 4-6 inches of soil, and water moderately or they will rot. These potatoes will only produce new tubers in the soil about 6-12 inches above the original seed potatoes, so when the plants are about a foot above the soil, if I have any new add seed potatoes and the container has enough room, when I add more soil I may consider adding a few more seed potatoes that will produce "baby potatoes" above the older tubers, then cover them with another 6 inches of soil that will also bury more of the new growth of the first seed potatoes. Doing this stimulates more growth, and I may even add even more soil as the plants get taller depending on the depth of the container. I don't always add the second layer of seed potatoes, but doing this produces a few larger potatoes below (Baked Potatoes!) and a lot of smaller potatoes above them, and they are all excellent eating. I am growing Russet, Golden, and Red potatoes in containers, but I think they are all determinant varieties since they are all started from potatoes purchased in grocery stores, and each plant only produces tubers in the area near the seed potato, but do not continue to produce tubers as the plants get taller no matter how much more soil is added. I am still learning as I go, such as "location, location, location!" is making a noticeable difference on how successful my efforts are, and I would like to find an indeterminant variety potato that will grow well in Zone 10A.
