How much sun do potatoes need.. Can they be planted in the morning shade and evening sun

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.

I would like to endorse the comments above regarding the use of tyres to grow Potatoes or in fact use to grow any any food. The rubber compounds in both the carcase and tread contain significant numbers of nasties. Tyres are designed to perform at high speed under quite arduous conditions, absolutely not designed as end of life food growing receptacles! They contain many potential hazards/chemicals, far too many to fully list. I will list just a couple,so that fellow readers who do not have my background can appreciate better what they are dealing with. Firstly the reinforcing Carbon Blacks utilized in the rubber compounds, contain significant amounts of Organo-Nitrogen compounds, blacks of this type are banned for use with any "Potable Water" applications! the reason being these compounds are considered as being high risk carciogens. There are special Blacks made specifically for food contact applications, rubber reinforcing blacks are definitely not suitable. Processing aids, The rubber in the tyres must be made to be strong/resilient/heat resistant; specially designed chemical compounds are encorporated into the rubber compounds to achieve this. The chemical compounds used present problems in many directions, firstly they are not ( dont need to be) pure compounds they contain debris from the chemical synthesis processes used to make them; these same compounds also decompose both during Vulcanization and during the life of the tyre. The Organo-Chemical families many of these compounds belong to include compounds that are considered hazardous and not suitable for food contact. The possibility of side chemical reactions between both the impurities and the debris from the degradation, resulting in compounds that could present significant hazards is real. Are tyres dangerous? yes! when attached to cars driven by idiots and when used as receptacles to grow food; otherwise no!
