We constantly find potatoes growing in our compost (usually green ones I've thrown in) so I have long since stopped buying seed potatoes! Potatoes that are just starting to green, I just peel til they're not green anymore and never had any side effects. That said, one of our dogs ate a rather green potato while she was a pup...the associated get bill made for a very expensive potato crop that year...!

How long should my Potatoes take to grow? I have just tried to dig up one plant and the potatoes are still really tiny so obviously not ready yet. How do I tell when to dig them up? Should I be fertilising and if so with what? Thanks

Hi Lynda, potatoes take about 5 months or so to grow to a good size. You'll get an assortment of sizes. They're ready to harvest when the vine starts to wither. The smaller potatoes are good to keep for next year's crop. If the vines aren't withering after 5-6 months, you can try to kill them off yourself, apparently that's what they do in Idaho (or so a friend tells me!)

I planted tubers on 1st july and they are already growing. My large potato tub is looking like trees at the moment as all the potato tubers have sprouted. I find this to be a good time of year to plant tubers. I'm located in Brissie.

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!
