I don’t have felling license know bugger all about trees apart from they need felledi would say
When does an overgrown piece of hedge become a tree?
I've been happily clearing a field that's been untouched for 30+ years, which included a number of self-sprouted trees that might have been in excess of 8cm, together with reducing to 1m height said overgrown hedge and some of those branches/trunks were 30cm or more. Do I need a felling licence? Or should I have got one, more to the point?
