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 www.potatoesnz.co.nz . 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 www.potatoes.co.nz 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!

End of February can I plant potatos now? Position not a lot of sun and no frosts

If you've not got anything else to plant give them a go. I have grown potatoes on the east side of the house which is shaded by flats next door first off then the house after midday. You're not likely to get the yield that you would with a spring-planted crop but any potato is better than no potato! Trust this helps.

If I planted seed potatoes now (Feb 17) is there any chance I'd get a crop before winter sets in?

Potatoes need about 3 months to harvest from planting for 'new' potatoes. That is about a month after flowering. If you can get 3 months before frosts give it a go or plant them in a frost-protected area. New potatoes are delicious but won't store like Old potatoes which are harvested after the tops die off. Trust this helps.
