Hi Lisa, yes the actual potato is green if it has been subject to light so you should keep the plants well mulched in case the potatoes are close to the surface, my spuds are still showing no signs of shooting, they are in the potting shed in egg cartons, will they shoot soon? Or shall I just plant them now? They are certified seed spuds.

i have planted potatoes about 3-4 weeks ago (i didnt bury them as i have very hard soil here) and have been covering them over as they shoot. how long do you have to do this as i keep getting told from people there should be no need to cover them over as they grow. also the poisonous thing is a bit scary - how do you know if the potato is green? is the actual potato that you dig up a green colour?? thanks, L

I am so confused about how to sprout seed potatoes. My local nursery says keep them in the cool and dark but a reputable gardening writer spent a page saying keep them in the warmth and light. My Ruby Lou's have only about 1/2cm of growth after almost 2 months. Please help!!!

I notice people have already planted potato tubers? Am I too late?

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.

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....... :-)

It depends -- not all potatoes are suitable for towering (layering). Additionally, I have found that the potato plant SPENDS A LOT OF ENERGY GROWING UP, UP, UP, as you cover its leaves with soil (leaves have specialized cells designed to collect light - and why you would want to cover them with soil is beyond me this is not really a good move -- leaves are not roots). My recommendation is: if you have a DEEP PLANTER bag starting at about six inches from the bottom -- in sort of a pattern that looks like the 5 on a die (dice) -- make about 3-4 inch round holes -- and make them on the sides that receive light keeping the holes about 10 inches apart (6 inches away from the bottom and 10 inches away from the top of the bag). Fill the bag with a good soil/compost/manure mix of some kind -- starting from the bottom -- when you are level with a hole, place a seed potato there, level or slight below the bottom lip of the hole, and about 3 inches from the side of the bag (so there is soil between the potato and the hole) -- continue up until the bag is full -- the top layer of potatoes can be planted as usual. Yes, the soil will come out of the holes ... not to worry -- just be sure that the soil covers the topmost holes by at least 6-8inches. That is - each potato planted in the bag should have access to a WINDOW (air and light) OR those planted on the top layer (like a usual planting) should be down about 9 inches or so. The Key to this planting is ALL potatoes need to be able to put leaves somewhere -- they will follow the air and light to find that spot -- all potatoes need water -- so you will be watering from the top of the bag only (like a potted plant) -- but you water DEEPLY, since the water needs to make it to the very bottom potato plants -- so maybe you water every 5 days or so... depends on the soil, temperature, amount of light , amount of wind/air (which whisks moisture away), Additionally, ensure there is drainage at the bottom of the bag .... maybe a two inch hole directly at ground level. It might be better to use a crate of some kind.... rather than a bag...anyhow this set up will work with any kind of potato plant without consideration as to whether or not it can handle towering. Hope this helps. Conversion of inches to cm : 1 inch = 2.5cm
