My growing potatoes this year, didn't amount to much in a container pot. however, next year I hope to have some raised beds if all goes well with pallet collecting and bin making. I actually got 4 tiny little thumb sized potatoes. Although I must admit, they were from the farmers potato crop this spring. But all an adventure and learning is fun!

Need to get seed potatoes
Store bought have sprout nip sprayed on them to keep the eyes from turning to sprouts

You can get results from store bought ones if you place them in a dark cool place with a few onions.

The gas onions give off causes potatoes to sprout.
You may notice if onions and potatoes are stored together
The potatoes develop eyes and sprouts quickly

For long term storage
Keep them stored in separate areas or your potatoes won't make the winter

They'll have eyes a foot long and be shriveled up

And is there a way to make this spray for the eyes ourselves?

I installed a new packaging line in a "little potato" processing facility just over a year ago.
We could not use certain types of conveyor belting as the sprout nip erodes the belting material.
I no longer but or eat little potatoes as a result.
Grew up, growing our own.
Do so if you can
Potatoes use alot of potassium from soil so it is good to either add it the next year or rotate to new soil.
The scabs, or brown spots you find on potatoes is usually a result of lack of potassium.
Potash is your best bet
It contains alot of salt as well, so makes acidic soil basic

I seem to have that in common with potatoes, I need potassium! hehehe.💛

TY for the advice though, I plan to do much more growing in the future if I can, going to be working on making some raised beds out of pallets that were heat treated and make some almost like mini-greenhouses with each of them, however with access for bugs, more like a netting.

Grew up late seventies, early eighties.
Interest rates were at 22% so we grew everything in a massive garden.
Canned, bleached, froze stored all our own veggies.
My job to look after it.
Eight kids at one point.
Raised cows, chickens.
Eggs milk and made our own butter.
I'm not the world's best expert but learned alot by trial and error.
Resented it as a kid, but blessed for it now.
I might not know it all but if you have any questions, feel free to shoot them my way
I'll be more than happy to share what I know.
