Orchard (more than 1/2 acre)

If you're thinking of planting an orchard, you probably already have a good idea what varieties you want. A few people have asked for advice on planting orchards.

The new varieties are not much tested in BC yet, so we recommend planting as much diversity as possible to maximize your chances for good yields. 

One example of a good mix for 1 acre at 9 x 18 spacing (double density to maximize early yield) is:

Jefferson 80
Sacajawea 80
Yamhill 80
Eta 9
Theta 10
Gamma 10
