Really stupid question on creating a master plan
Here goes ...
I want to create a "master plan" for my backyard. The first step is measuring what exists. I've seen plans that show big trees as 2 circles - a small one for the trunk & a big one for the size of the crown (so you can plan for shady areas).
How do you know how large to draw the crown circle? The tree trunk diameter is easy enough to do with a tape measure & a calculator. But I can't begin to guess how to measure the diameter of the crown of the oak trees we have. That's sort of a lie, I can think of one way but it requires a bucket truck & that just seems impractical.
My feelings won't be hurt if you roll your eyes at the noob & her dumb question ... so long as you give me a hint on how to do this :)
