The containers you suggested would be ideal. If you are using a bath take the plug fitting out, to improve drainage, and put a layer of stones or crushed rock like (railway ballast) in the bottom to improve drainage. Cover this layer with old jeans, newspaper or cardboard. this will help hold water and stop sediment from blocking the drainage. Add a layer of potting mix or growing medium and then a layer of old manure or blood & bone. Cover this with more mix and thenspace your seed potatoes out. Cover them with mix and give them a water. When the shoots emerge keep adding mix. Potatoes form on the stems not the roots. As with all plants growing in containers ensure thet they are in a position where the container will not get too hot as the roots will 'cook'. Attention to water is also important, mulching will help.

We are "virgin" vegetable growers with a small garden. Can we grow potatoes in big plastic pots that a neighbour left behind when she moved. These pots have a tube sticking out at the side at the bottom which i guess is for draining. We have 3 of these pots. We would like to grow new potatoes for Christmas. We live in Adelaide when would plant the seed potatoes. We interested in growing our own organic vegies. Appreciate any advice. Wish us luck. Regards Bill.

Potatoes can certainly be grown in large pots or tubs. If the pots are about 15 to 20 litres (or more) they wil be ideal. Do the pots have a separate bottom in them? they may be self-watering pots. Put some newspaper or a layer of old cotton clothes or part of the leg of an old pair of jeans in the bottom. This will help hold water and will eventually rot, helping to build up the soil. Add a layer of good potting mix then a layer of old rotted manure. Follow this with another layer of potting mix so that your pot is about half full. Place a couple of pieces of potato or 'seed' potato on this layer and cover with potting mix. Consistent watering is very important for all plants in tubs. As the shoots emerge keep adding potting mix until you have reached the top (some weeks). Potatoes form off the stems on this section of the plant, not off the roots at the base. In colder areas leave planting until late winter. In Adelaide you may be able to put the pots in a sheltered spot and grow them throughout the year. You should have no difficulty having new potatoes for Christmas. New potatoes can be bandicooted about a month after flowering. Just scratch down beside the plant and take them, being careful not to disturb the plant too much. When the tops die off we call them old potatoes. These ones will keep longer. We are very happy to support you in your venture, all my answers or comments will be 'organic'. Keep the questions coming, remembering: 'there is no such thing as a dumb question'. All the best in your move to grow your own 'clean', healthy food.

Hi Toni My husband and I have had a small crop (20 or so) and grown these rotating each year. Unfortunatly we believe we must have inadvertently eaten our saved ones and now we cant source any. We are in Wellington and I know it's a long shot but wondered if you could help. Kind regards Sarah

Can a potatoes be grown in self wicking containers or would they get too damp?

Potatoes can be grown in wicking beds. If the beds are set up correctly they will only 'wick' the water that they need.

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!
