when to trim off jack pine lower branches
I have about 30 ten year old jack pines that were seedlings when I bought my home. They're quite large now (10 -20' tall) and have spread out to where they are pretty much touching along the bases.
I'd like to trim off the 1st 5' or so of the trees but want to know what time of year is the correct time to do this.
thx in advance for any help.
