Lisa - I would advise against eating anything grown in tyres, especially any tuber. Sorry. Tyres contain (among other elements) cadmium, lead, and zinc. Not too late to start a 'no dig' option....... :-)

My spuds have been in for 11 weeks now, they have a huge amount of green leaves. How long before they flower, and If they don't flower when can they be picked?

jane along as you dont eat these potatos because they are now piisonous but you should be alright with the others aslong as they arnt exposed to light and i dont now weather this will aid in production of spuds but oh well see what happens

I just purchased a couple of bags of seed potatoes. Will they last till Spring?

I have 2 bags of seed potatoes to be planted and leaving them in the light they are turning green. Is this okay?

Hi , I have just acquired a large pot , about 500 litres In Tasmania last month and purchased some seed potatoes , about a kg of mixed variety Going to drill some holes in the side of the pot at the base , add some plastic grating , old bread tray . add a couple of bags on potting mix and plant the spuds . I am thinking of then adding straight mushroom compost from the mushroom farm covering the plants as they grow ( after about 100cm ) leaving some fresh growth on the top. will the mushroom compost be enough , I can get a box trailer load for $30 from the mushroom farm and it has a mixture of what looks like black compost mxed thru it

Jenny, the problem with potatoes planted now is that any frost will knock the tops off. If you are in a frost free area or can arrange a frost free micro-climate for them, then you can certainly plant potatoes now. I have a number of volunteers growing at te moment, but I don't expect them to last unless I cover them well. Don't expect too much growth for the next couple of months, though.

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!
