Removing Leylandii in UK: Stump Options

UK: eight 18-ft leylandii at garden foot, 10 years old. Want total removal. Easiest method? Cut to 2–3 ft and poison stump? Or dig out?

The expert said leylandii doesn't resprout from stumps. Once cut, roots die. Stump removal options: 1) Dig trench 1 ft out, cut roots, undercut, last root pops free. 2) Stump grinder (hire/rent). 3) Cut low, drill 1-in holes, apply stump rot accelerator, cover with soil, keep moist—rots in 3–4 months. Roundup on stump only needed for resprouting species (birch, holly, willow).

Stump Solutions

• No resprout → roots die naturally.
• Dig out, grind, or rot chemically.
• Roundup unnecessary for leylandii.
