Where can I buy Idaho seeds, all we get are fancy yellow fleshed spuds here in supermarkets and they are VERY inferior to Idahos. I grew up with Idahos and I would dearly love to get hold of some seeds to grow them. I live west of the Devide in southern NSW where it is very hot in summer. Thanks in anticipation. Jim.

You certainly can grow potatoes without chemical sprays and fertilisers. Potaoes have been grown for hundreds of years without them. The soil needs to be friable or cultivated to at least 200mm (8") deep and have old manure worked into it. Plant the potato pieces about the same depth in the soil then cover. This depth is to reduce the chance of potato moths getting to the tubers to lay eggs. As the potato shoots emerge hill up around the stems with more soil or mulch and keep them watered. Potatoes are generally pest free and rewarding and a few can be scratched out about a month after flowering with the remainder harvested when the tops die off. Store the potatoes inside or in an airy, insect-proof container away from light. All the best with your potato growing!
