Hi I have been and got my seed potatoes and have got them chitting away in the garden house. Now these potatoes are the kidney shaped salad ones so are not very big at all so when I filled my pot up at the garden centre I got a fair few something like 40+.
I will be growing them in 30ltr buckets with some home made and shop bought compost  and will add potato fertilizer as well.
My question is how many seed potatoes can I plant in these 30 ltr pots all seeds are the same size or there about 3" long shaped like a kidney.
This will be my first full year down the allotment and I am so looking forward to it so I guarantee that this is first of many post.
Cheers
Paul

I have some tubs that hold 35L if filled to the top and I use 3 potatoes for those.

Similar here - 3 early/second early or 2 maincrop per 30L pot + a handful of BF&B

Even though the potatoes are real small you would only put three per pot ?
Normal sized potatoes that you plant in pots are usually three per pot.
What sort of crop am I expected to get with only three small potatoes in each pot ?

The way I look at it, no matter the size of the seed potato it will still make a plant, so it's 3 plants per pot.

The most important rule is to match the number of seed potatoes to the size of container you are growing them in. As a rough guide each potato plant needs about 10 litres, that’s just over 2.5 US gallons, to grow into. Cramming your potatoes in is a false economy, the result being very small spuds, if you’re lucky enough to get any at all. A typical dustbin-sized container would hold around four plants. Potato growing sacks sold specifically for this purpose, would house three.
