Hello to all. I am starting to study up on, picking out my trees, and learning about forest plantings. I am going to use trident maples, and do a seven tree layout, and they range in trunk size from 1/2" to 2". Do you use the same proportions as with a single tree? as in from 1/4 to 1/10 for each individual tree? and, is there an area size to accomodate a main tree that is 2". as in how large should the entire planing area be for a seven tree with the main 2" #2-1.6", #3-1.1", #4-7 about 1/2" ? I would think for a main tree that is 2" thick, and around 20" tall would be a pretty large layout. Anyway, thanks for any input.
