My potatoes are growing rather nicely however in the last couple of days I have noticed that the leaves are looking "skeletal" I did see what I thought was a lady beetle on the leaves- but much bigger. Could this be the culprit? How do I organically control it?

It could be the 28 spotted potato ladybird with out seeing a picture it is hard to say. There are some ladybirds that will eat away at powdery mildew if there is none of that I would most likely say it's the potato lady bird. It will be 6-10mm long, a orange colour with 26-28 dark spots. With the skeletal looking leaves it would be its eggs. There are no chemicals registered for control of the leaf eating ladybirds in home gardens. You will have to remove by hand and squash the larvae and egg clusters. Natural predators that will kill them are parasitic wasp, birds & assassin bugs. So might be wise to encourage these into your yard. Remove any weeds you have in the garden as well. Other plants they will attack are cucumbers, eggplant, pumpkin and tomatoes and some weeds such as nightshades.

Joey, you can certainly plant a variety in one plot. The Sept/Oct 2008 ABC Organic Gardener magazine has a guide to a 'bumper crop of potatoes' - maybe they list some suppliers?

I am noticing coppery (pearlescent brownish) marking on the leaves of otherwise healthy looking potato plants, planted in potato grow bags. I've been monitoring the soil temperature and it had reached 30C until I placed cardboard and bubblewrap insulation over the black fabric bags. It is currently mid-August. I'm in Brisbane. The coppery leaf markings surround the veins rather than being on the fringes of the leaves. The markings do not look like the brown/black spots of wilt. Any thoughts from you potato growers out there??

The main article states:"Potatoes exposed to light will go green, so keep them covered up with straw and soil as they grow." Does this mean I need to cover the complete foliage or just hill up the plant? Thanks.

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.
