I have all my seeds. Never got around to starting tomatoes. Might try to work that in next week. Got to add compost to the volunteer potatoes, companion plant green beans with them, and put down some straw to help keep the moisture in the sq. foot bed of Mel’s mix.
As far as I have heard, “volunteer” potatoes would be something you want to stay away from.
A “volunteer” plant is one that grows from seed. This means cross breeding. Since there are so very many solanum species, potatoes might just latch onto something a little dangerous...
Potatoes that just grow from potatoes left behind in the ground from last year are fine. Heck, I haven’t bought potatoes in years, I just wait for the stragglers to sprout or actually plant potatoes I have bought (to eat) to sprout.
