Top tips

Hiring a tree surgeon, without the regret.

Four moves that separate a smooth job from a nightmare.

Lion-Tailing

Removing too many inner branches, leaving foliage only at the tips. This makes branches heavy and prone to snapping in high winds.

Over-Thinning

Removing more than 30% of the canopy can shock the tree, leading to an explosion of "epicormic" growth (thin, weak shoots).

Bark Stripping

Dropping heavy branches without using proper "undercutting" techniques, which can tear the bark down the main trunk.

Garden Damage

Failing to use lowering ropes can result in heavy timber crushing your lawn, flowerbeds, or patio.

Costs & timeline

Know what it costs. Know when it ends.

Indicative UK ranges and what affects price.
