About 10 years ago I put a small walnut tree in the garden and 2 years
later pruned it to shape with 3 almost equally spaced uprights from
chest height.
For the last couple of years it's had a couple of hundred walnuts each
summer (and a couple of squirrels...)
I now wish to prune it again to give this larger tree a more
diffinitive shape and less shade to surrounding areas.
At about 12 feet from the ground the branches are about 1 1/2" thick
and where they fork, I was thinking of cutting them leaving an upward
or sidewards bud or shoot.
Is it OK to do so at this time of year and anything I should watch out
for?
