Planting a crop is about planting at the right time for germination (soil temperature) and then the right air temperature for growing the crop. Then consideration should include hot or cold weather, likely hood of heavy rain, possibility of frosts. It is just not a case of I will plant something when I want to.

Potatoes will not tolerate frosts so if you get frosts delay planting till after the last frost. If you are in a frost-free area their is no reason why you couldn't plant them anytime.

If you contact Tui Seed Potatoes they have a list of available 'certified virus free' potato seed available, New Zealand Potatoes and Eurogrow also have potatoes where you could get a list of varieties available in New Zealand. They are suppliers to farmers and resellers but could direct you to retail outlets.

How or where can i get kipfler potato's.

I contacted Eurgrow Potatoes in Hamilton and they do not have it available but said you could try Merton Smith Dawe in Christchurch or Siesta Bulbs in Palmerston North. They package bulbs, potatoes, etc for nurseries, garden centres and so on. Eurogrow were familiar with Kipfler but said that it was mostly only available from organic markets, community markets, etc. All the best in your endeavours.

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

Are you looking for SWEET potatoes or regular potatoes ..... I think your climate is better suited for Sweet potatoes -- they are different (different families) and therefore have different instructions: The ideal soil temperature range for planting potatoes is 45 to 50 degrees Fahrenheit (7 to 10 degrees Celsius). After planting, the ideal temperature for growing potatoes is 60 to 70 degrees Fahrenheit (16 to 21 degrees Celsius). Potatoes do best in fertile, well-drained soils. However, potatoes will grow in many types of soils. Soils that are poorly drained tend to produce poorly shaped potatoes and tuber rot. Potatoes do well across a wide range of pH, but prefer slightly acidic soils; a soil pH of 5.3 to 6.0 is typical for potato production. If your soil is more acidic than this, mixing in wood ash will help raise the pH and make your soil more alkaline. Sweet potatoes (Ipomoea batatas) are close cousins of morning glory and only distantly related to traditional potatoes. They are tender, so must be protected from frost, and like heat, full sun and regular watering. They crop best at temperatures of 21–26°C (70–80°F) PLEASE CLARIFY which type of potato.
