Most plants need about 5 + hrs. Look it up on the internet, google it.

We used seed potatoes to grow Kilgore in our school garden. As the tops have now died off we harvested them today, only to yield Ferny tiny potatoes. Less than 300g from a whole 3.6m x 1.2m garden bed. The potatoes were watered a minimum of 4-5days per week, were regularly fertilised and grown beside sweetcorn. How did this go so wrong. We yielded less than the bag of seed potatoes that we planted. The soil was beautiful and rich. We mounded around the growth for the first 6weeks. So disappointing. Any help greatly appreciated.

I would say you over fertilised them way too much, and probably too much water. That would produce a lot of leaves and little potatoes. In future prepare the ground adding manures compost etc., don't over do it though. They WILL NOT require any more fertilising. When young a lightish watering each day or two. When bigger a good watering 2-3 times a week, depending on temperatures. Put your figer in the soil to see if wet or dry and water accordingly.

I'm not quite sure of my zone. I live in Charlotte, NC 28208. Can you please tell me? Check here www.gardenate.com/zones/#zone-US (Editor)

Are the green potatoes safe to eat? I always get a few in my crop

IT IS NOT SAFE TO EAT THEM. It is caused by the potato being exposed to the sun. In future keep the potatoes covered with soil to stop this happening.

Can I plant seeded potatoes the week after Christmas for a winter crop? And also if yes what seed potato would be the best? We live in north Canterbury

First decide whether you are temperate or cool/mountain - look in the climate zone section. Then read up about the planting times. Then you decide what potatoes you are going to plant. That will depend on what is available in your area.

When do they harvest potatoes

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.
