How many / plant spacing.
So after my last post I made some calls to local growers to see about possibly getting some onion sets and seed potatoes. My favorite grower has an organic farm (though he refuses to acknowledge that fact and get certified) and he offered to find me some of each if I could tell him how many I needed. Obviously each onion in a set yields one onion so that's easy but roughly how many potato plants would I need for a family of three? One other question: How far apart do cucumber/pea plants need to be in order to prevent cross pollination? I have two types of each and while my cross pollinated tomatoes turned out to be super delicous last year, I'm not sure what kind of disaster I could create by crossing lemon cukes with english cukes.
