I Think My Garden Tree Might Be Dead — How Can I Tell, and What Should I Do?

Each spring, without fail, we visit a number of gardens across Grange-over-Sands, Kendal and South Lakeland where a homeowner has become concerned over winter that their tree might be dead. Sometimes it is. More often it has simply been dormant and comes back into leaf a week or two later. Occasionally it is somewhere in between, alive but in serious decline. This guide will help you tell the difference.

The Simple Scratch Test

The most reliable way to check whether a tree or shrub is alive is the scratch test. Using a fingernail or a small knife, gently scratch the bark on a small, live-looking shoot or twig from the previous year's growth. Scratch just deep enough to remove the thin outer bark and reveal the layer immediately beneath.

If what you find beneath the bark is green, or pale green, the branch is alive. If what you find is brown and dry, that branch is dead. It is worth checking several twigs at different points on the tree, because a tree can have some dead branches and some living ones. Check twigs from the outer ends of branches first, then work back toward the main stem to get a picture of how extensive any die-back is.

When to Do the Test

The best time to check is from late February onward. Before that, even a completely healthy deciduous tree will look completely bare and lifeless in winter, which is simply its normal dormant state. By late February or early March, a healthy deciduous tree should have visible buds forming on its twigs, and the scratch test should reveal green tissue beneath the bark.

If you are checking in mid-winter and the tree is a deciduous species, the absence of leaves tells you nothing about whether the tree is alive. Wait until late February or early March before drawing conclusions.

Species That Take Longer to Wake Up

Some tree species are naturally later to come into leaf than others, and this catches people out every spring. Ash in particular, in normal healthy circumstances, is one of the last native trees to come into leaf in spring, often not leafing up until late April or even May. If you have an ash tree that looks bare when everything else is in leaf in April, this is not necessarily cause for concern. However, given the current situation with ash dieback across Cumbria, it is worth checking the twigs for the characteristic glossy black buds of healthy ash and doing the scratch test to confirm whether the tree is living.

Walnut is another species that is notoriously late to leaf, and many homeowners in Cumbria have a moment each spring of anxiety about their walnut tree that resolves itself in May when it finally comes into growth.

Other Signs That a Tree May Be Dead or Dying

Beyond the scratch test, there are other signs to look for.

Bark that is falling away from the trunk, particularly if it is coming away in sheets revealing dry, pale wood beneath, is a sign that the tree is dead or has been dead for some time. Living bark adheres firmly to the wood below it.

An absence of buds on the twigs by late March or April, when other trees of the same species are clearly showing bud break, is a strong indication that something is wrong.

Fungal fruiting bodies, particularly bracket fungi on the trunk or at the base of the tree, can indicate internal decay that may or may not be associated with the death of the tree, but always warrant a professional look.

A large number of dead branches throughout the crown, combined with a sparse or absent leaf canopy in summer, indicates a tree in serious decline even if it is not yet completely dead.

What to Do if Your Tree Has Died

If your tree has died, the key thing is not to leave it indefinitely. Dead trees in gardens near houses need to be assessed and, in most cases, removed. The structural integrity of a dead tree deteriorates over time and the rate of deterioration varies by species. Dead ash in particular becomes structurally unreliable quite rapidly, as we explain in more detail in our ash dieback safety guide.

A dead tree near a house, garage, garden wall or area where people walk or sit is a hazard that should be dealt with on a reasonable timescale. It does not need to be an immediate emergency in most cases, but it should not be left for years either.

We offer free site visits and assessments for homeowners across Cumbria who are concerned about a tree. We will tell you honestly what we think and give you a clear, written quote for any work needed.
