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.

I have never tried this. As the plant grows just add more mulch/soil around the plant but don't completely cover all leaves. Leave the top leaves out.

The leaves on my potatoes seem to be shriveling and dying. Leaving crisp brown holes in the leaves and dead stems. Could it be a fungal disease or insect attack. If it is fungal disease what should I treat it with. Could it be viral?

How old are your plants? The leaves and stems will die when its time to harvest.

They have probably grown tall because of one or both of two things - too much nitrogen or if they had to compete for light -(tall nearby plants). I think the guide here say 12-16 weeks to harvest. The leaves will die off when it is time to harvest. My plants powered along (fed plenty of composting mulch - then they have just died - only about 12 weeks since shooting out of the ground. I pulled out one plant - a few big potatoes and a few smaller ones. Have left the others in until I need them to eat.

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.
