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

Hi.. when is the best time to dig Red Dakotas.? They are flowering at the moment.Should I wait until the flowers die off?? We live in the Mackenzie Country...Frosts probally will start April..Thank you

About a month after flowering you can carefully dig around the plant and harvest 'new' potatoes. These are delicious to eat but will not keep. Potatoes harvested after the tops have died off in late autumn are called 'old' potatoes. These will store well in a cool, dry place until early spring when rising temperatures will cause them to start and sprout. All the best.

Can you recommend a variety of PURPLE potato please?

I am in Australia and varieties of potato that are available vary across the Tasman. Check with Potatoes New Zealand at . They list Purple Heart with purple skin and flesh and Purple Passion with purple skin and yellow flesh. Trust this helps.

1 acre how much seed do I need what's the best variety how much fertilizer give it a go

What variety you grow depends on wht you want to use them for eg. mashing, baking, chips, all rounder, etc. You could contact for the most suitable variety to grow. They would also be able to guide you on fertilisers or other soil amendments.

The quantity of seed you would need depends on a number of things - how wide the rows are, how good the soil is, how you are going to cultivate them, etc. As a guide you would need 5-800 kg/acre. I would suggest you contact your local Primary Industries or Agriculture Department for a more accurate quantity. They will know your area and often have charts allowing for different row widths and planting densities to calculate quantities. Happy spud growing!
