My brother asked me this weekend about consequences of pruning a
neglected 40' Northern Spy this time of year - and I couldn't give him
an answer. The tree was planted by my Father who passed six years ago -
And I doubt he'd done any pruning for years.
One limb to go ASAP is a 8"+ diameter one about five feet of the ground
that interferes with lawn mowing. Just doing that would be a big help -
and the more serious pruning could wait until dormancy. This tree is so
big that a bucket truck will be necessary to reach the top.
The tree is located in the Boston suburbs - zone 6.
There is some fruit - but nothing I'd want to eat!
All thoughts welcome! Thanks!
