i need help quickly. i have a conifer hedge that is now 30 foot tall, (about 20 years old) and needing to be cut by at least a third. will this kill the trees?????
no jac it wont kill them take what you want off the top and just trim all the sides so they wont go brown good luck hope you have a high ladder.
nothing kills conifers in my experience!lop as much as you can off the top first then the sides.but make sure you put long sleeves on,i did mine a few years ago and had an itchy rash!nice smell tho.
thank u vedun its surprising what home grown veg can do
