Thank you for telling me all about growing potatoes. At school our project is to grow potatoes independently. Thank you, your web site has helped.

Thanks Emma. Yes I know about green potatoes being poisonous that's why I was worried about planting them but I think, like you, that the new ones should be okay. No shoots appearing yet though, still a bit early to plant here.

Regarding the earlier comments about frost, i once flatted with a woman who forgot to harvest the container potatoes she was growing before the frosts arrived - and it can get down to -5 here, although -2 or -3 is more usual - and they came away again the next spring. i have no idea how the crop turned out, since i moved out before she dug them up, but it's worth bearing in mind that potatoes are the storage unit for the plant. if your plants get frosted, it just might mean that you have to wait until the next year for your crop.

Ivan, if i remember rightly, your potatoes will be ready to be dug up once the leaves start turning yellow. for main crop potatoes - those that grow later in the season, you can wait until the tops die down completely before you dig, and this will help them to keep longer. if your spuds are earlys - growing early in the season, just start digging when the yellowing starts.

Lisa, just leave your potatoes in the tyres for their entire growing season - i doubt they like being moved much since they are a root crop. you can increase the size of your crop by adding more tyres on top and filling with soil or potting mix, whatever you're currently using. leave a bit of green growth poking through though - say around 5cm or so. you could easily stack 4 or 5 tyres high.

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?

Hi Jane They should still be ok to plant and produce more potatoes. You won't be eating the main potato seed anyway, that's normally rotted by the time you harvest them. As Gareth says all green spuds are poisonous.

Thanks Gareth, that's what I was hoping.

That's a big subject! I'd say it depends on what you're trying to achieve. Do you just want a few really good veggies? Do you want to grow as much of your daily food as possible? Does your garden need to be aesthetically pleasing? There are lots of books on container gardening, you could try browsing your local library online. If space is limited, I say think about which veggies you love the most, which are pricey at the store, and which are most improved by eating fresh. Basil and salad greens for instance, are very easy to grow but very overpriced at the store. Corn and tomatoes are so much better homegrown. Whereas potatoes and onions are cheap at the store and not THAT much better homegrown so they're only worth it if you have plenty of space to devote. My advice for a beginner would be to start small and manageable, and build on that each year. Maybe this year buy a couple of Earthboxes or DIY a knockoff, and just grow a few of your favorite veggies. This will also reveal what some of your challenges might be. For instance my first year raccoons ate all my sweet corn, that taught me I would need a good fence in the future. ;-)
