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?

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.

As your potato plants grow higher, continue to mound soil/compost around the stalk higher and higher until it is time to harvest the crop/plant. New tubers grow out from the stalk which grows up out of the mounded soil. Exposed tubers turn green and become inedible. Some people place old tyres around the plants and fill them with compost to continue growth upwards. When the leaves begin to yellow off is about when the new taters are ready to pull up.

Sandra, the 28 spotted lady bird - yellow with 26 to 28 black spots - is a pest that eats all the green leafy parts of potatoes, cucumbers, zucchinis, pumpkin! I just pick them off and squash them...

Can potatoes be grown in old horse manure or does something else need to be added??

I'm new to growing potatoes or much else for that matter. My potatoes had started to sprout nice green plants about 6 cm tall. They seem to have been decimated I think by brush turkeys, I saw one near the patch but am also now thinking that they have raked the patch so other plants have not come up. There were also some fox droppings and also i think some wallaby droppings. Even though it is a bit late I'm going to plant again. How do I protect them?

Steve, it would be best if you use the manure in making compost. It has a high nitrogen content which can damage plants if used direct.

Do I need to purchase special potato tubers or can I use supermarket potatoes that have developed eyes. What are the ricks with planting old supermarket potatoes (if any).

Place 4 sheets wet newspaper on the ground,add one car tyre. Into the tyre place a good handful manure and water well. Cut up your eye potato into pieces (each with an eye) and dry for a few hours. Place pieces directly onto the wet manure and fill tyre with compost or soil. Cover with sugar cane mulch and stand back!!! Plant dwarf bean seeds under the mulch = 2 crops in one, very quickly.
