For a home orchard, how far apart should I plant the trees? My space is 62' x 22'. I'd like to grow apples, necterines, apricots, and pears.

Thank you.

I am not sure how far apart to plant them, but you definitely want to plant dwarf trees.

Stacie, have you planted yet? If you go with semi-dwarf Apples, the vigor of their varieties, and soil fertility play a role in their eventual size. Pears can take off, so plan to prune yearly to control them. Apricots & Nectarines just die... At least mine did.
Spacing is a good question, most "modern" apple trees are grafted to a semi-dwarfing rootstock, look around the neighborhood at younger trees and take a guess that yours will look similar. I'd expect an 8 foot diameter crown for a healthy Apple or Pear.
Though I wasn't joking about the Apricots & Nectarines ~ Nects (Peaches) can really spread, plan on some heavy pruning to keep them contained. And are you sure about the Apricots? Guess I'd treat them about the same, or, "replace" those two ideas with figs @ 10 foot diameters; and Asian Persimmons, back to 8 foot crowns. Just remember you'll need room for a ladder!
Good luck!

Depends on many factors, or so I would suppose. I wanted to plant a so-called "Belgian fence," so I read and heard that, for this purpose, apple trees could be planted between 2' and 4' apart. I wanted more fruit (as opposed to less), and I also wanted the diamond-shaped patterns of a Belgian fence to be more distinct and smaller, so I planted mine approx. 2' apart. I used M9-M111 interstems, which can be kept small by lots of summer pruning. This was done approx. 8 years ago. So far, I'm very happy with the results. I'm trying to maintain the height of my Belgian fence at approx. 7.5' tall, which means that I can harvest, prune, etc. all of my apple trees without needing to stand on a ladder. Hope this info helps.
