Seven signs your tree may be dangerous

Most failed trees give warning first. You do not need to be an arborist to spot the common signals — you just need to know where to look. Walk your tree once a year, and again after every serious storm.

The checklist

If you tick two or more of these, get the tree inspected.

  • Fungal brackets at the base or on the trunk — often a sign of internal decay
  • Large deadwood in the canopy, or whole limbs with no leaf in summer
  • Vertical cracks or seams in the trunk, especially where two stems join
  • A sudden new lean, or soil lifting and cracking on one side of the base
  • Hollows, cavities or bleeding wounds on the main stem
  • Included bark — a tight V-shaped fork rather than a rounded U
  • Storm damage: hung-up limbs, split forks or partially uprooted plates

Your legal duty as a tree owner

Under the Occupiers' Liability Acts, a tree owner has a duty of care to take reasonable steps to prevent foreseeable harm. In practice that means periodic inspection and acting on obvious defects. Trees near a highway, footpath or boundary carry the highest exposure.

Keeping a dated record of inspections and any work carried out is worth doing — it is what insurers ask for after a failure.

What can be saved

Not every defective tree needs felling. Crown reduction lowers the sail area and the leverage on a weak stem. Deadwooding removes the falling hazard while keeping the tree. Bracing can support a split fork. Removal is the last option, not the first.

When it's an emergency

Call immediately if a limb is hung up over a path, a tree has come down across access, a trunk has split, or a tree is leaning onto a building or power line. For genuinely dangerous jobs in Merseyside and West Lancashire we aim to attend same-day or first thing the next morning.

Common questions

How often should a tree be inspected?

Annually for mature garden trees, and after any severe storm. Trees over highways or in public spaces should be on a formal inspection cycle.

Does my insurance cover storm damage removal?

Often yes where a tree has damaged the property. We can supply written reports and itemised invoices for claims.

Can a leaning tree be safe?

A long-standing lean with sound roots is often fine. A new lean with disturbed soil at the base is not — treat it as urgent.
