I have a pice of land where I want to plant the potatoes. So I don't know what to do as a first step to start this project.

Can these seeds be kept for any length of time, if so how?.

I have tried several times to grow store bought kestrel potatoes, and whilst I get a great looking plant. Never one potato, whilst other bought ones produce. I am in SA. Are the Kestrals treated to prevent growth and is there anywhere I can buy Kestral seed potatoes when the season starts Thank you and look for a reply Ann-Marie

We are just harvesting our potatoes and find that several of them feel spongy but otherwise seem okay. What would cause this and are they okay to eat ?

Hi Diane, the small green berrys are actually seed pods, if you get these on your plants it means the potatoes are very happy where you've grown them and are in ideal conditions. If you use these seeds you can get a really good crop of genetically diverse potatoes unlike those grown from seed potatoes which will only produce clones. Cheers Tracey

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.
