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?

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?

The handbook-which I provided the location to in my prior reply is not very beginner'ish but it is comprehensive covering issues you may never encounter- but you do need the reference material. I have a few thoughts to add. 1. Hilling up while the plant is growing-if you are covering leaves I find this fundamentally wrong. Leaves are specialized and designed to collect light, they are not roots. So I opt to plant my seed potatoes deep enough on day one- however I tend to have the luxury of very well airated, light soil. This means the seed potato has a steady air supply and can sense the heat from the sun even at deeper depths 2. Your seedpotatoes need all their potassium Immediately. Potatoes strangely take up all their potassium that they need really early. -and don't uptake more. If there is not enough potassium in the very early stages your potatoes might have hollow heart (looks like hollow rotting middles). Late application of potassium tends to be useless 3. Potatoes seem to respond really well to the addition of microryzal fungi - in my area we source that under pine trees in a forest- we just take some forest floor duff with a dust pan and add to the potatoe planting soil. To sum up - your seed Potatoes should be about the size of chicken eggs (if larger cut up ensuring an eye on each piece and allow a few days to heal/scab up before planting). You need to chit them(make them sprout-place in dark so they sprout). Plant in soil with Compost, a sorce of potassium and microryzal fungi. If for some reason you cannot source any compost/pottasium/microryzal fungi -plant anyhow potatoes are tough -there is still a good chance they will be Okay -depends on the condition of you soil. In my area I can water deeply once per week. Harvest when about half the leaves have fallen over as if to die. If you harvest sooner you may be compromising on size-because as long as those leaves can collect light they can store the energy in the tubers. Good luck - it is so much easier than it sounds- and all those diseases in the handbook are rare and if the plants are strong (well fed) they can manage just fine, potaoes are pretty tough root crop. In other words- you can grow potatoe.
