Planted these 10 years or so ago. I forget what they are - I think a cedar - but they've grown a lot more than the tag said they would which I do remember was maximum height of 6.5 feet.
Anyway, anything to worry about before I go looking for a hedge trimmer? Safe to do? Good or bad time of year to do it? Good or bad way to do it?
