Oak tree defoliant
Glad to see this forum thriving. I haven't posted on here since I bought my Danby, which continues to be a great washer.
Now I have a question about thinning an oak tree. I searched for answers here but only found arguments about the ethics and advisability of killing trees - I just want to clear its canopy a bit.
This tree is handsome and very old, but has really challenged my gardening in years past (as well as provided a home for most of the zip code's squirrels...grr...I'm all for nature when there are natural predators). It occurred to me that I could lighten its very dense canopy, which is just starting to leaf out. Some kind of defoliant could be used discreetly, just sprayed up into it.
Some web research says vinegar and salt, which make sense, would kill leaves they land on. Oil helps these stick and work. These are all locally toxic; anything else that would work is probably much worse for water table. Just put some on a hose sprayer for some dilution and jet away no? After of course covering most of my yard. Has anyone had experience with these or other defoliants?
