Potatoes are ready to harvest when the plant dies and the tubers at here fullest of starch and size. If you are going to store them then wait until this time. You can start harvesting any time there is any size to the tubers (size of a baby's fist) but Cook and eat them straight away. Happy gardening-Timo

Why do you not grow Cucumbers and Potatos in the same garden bed?

Because they compete for nutrients and water and planting this way only diminishes potential harvest.

Whales, I have used this info to full extent and have even been inspired to grow some potatoes of my own, they are now about 2 weeks old and growing well

What, Why, How are green potatoes poisonous? If the plants have died off and the potaoes are not harvested. What will happen to the tubers

Green ends are not good and shouldn't be eaten. It means the potato has been exposed to the sun and light too much. It can be cut off though,

I may be wrong but I took it to mean that planting potatoes in tyres opened up vulnerability to you consuming the absorbed heavy metals which the tyres are said to leach, or release into the soil. I hope this gives help, even if only an alternative perception.

I have harvested my Dutch Cream potatoes, I'm a first time grower and seemed to get a reasonable crop. I would like to keep some to plant next year. How do I store them until next August? The seed potatoes I used were from an organic nursery.

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!
