How to Prepare Your Trees for Winter in Dorset

October marks the beginning of the storm season across Dorset and Hampshire. The combination of trees still carrying autumn leaf load and the arrival of Atlantic gales makes this the highest-risk period for tree failure. Getting the right work done now — before the worst weather arrives — is the single most effective thing a homeowner can do to protect their property and reduce risk.

Clearcut Tree Surgery carries out more emergency call-outs between November and February than at any other time of year — and the majority of them involve trees that showed warning signs in autumn which weren't acted upon. This guide outlines exactly what to check and what to book before the Dorset winter sets in.

Why Autumn is the Most Important Time for Tree Care

The period from late September through to November is critical for several reasons:

• Leaf load before leaf fall: Deciduous trees in full or partial leaf present a much larger surface area to the wind than bare winter trees. This dramatically increases the forces on the branch structure and root system — which is why the most destructive wind events for trees typically occur in October and November, before leaf fall is complete.
• Ground saturation: Autumn rainfall in Dorset saturates the ground, reducing the grip of root systems. A tree that withstood a dry summer storm may fail in wet autumn conditions under the same wind speed.
• Booking availability: Tree surgeons across Dorset become extremely busy from November onward as storm damage calls increase. Booking crown reduction, deadwood removal and inspections in October secures capacity before the rush.
• Nesting season is over: The bird nesting season ends in August. From September onwards, there are no restrictions on cutting based on active nests — giving full flexibility for any tree work needed.

What to Do When a Storm Hits

Despite the best preparation, storms will sometimes cause tree damage. If a storm affects a tree on your property, follow these steps:

1. Stay inside during the storm and do not attempt to inspect or clear damage while conditions are dangerous
2. Assess from a safe distance once the storm passes — look for obvious structural damage, leaning or fallen trees
3. Check for power line involvement before approaching any fallen material — call your network operator immediately if power lines are involved
4. Photograph the damage before any clearance begins — important for insurance claims and any TPO notification requirements
5. Call Clearcut on 01202 022560 — our 24-hour emergency service operates 365 days a year across Dorset and Hampshire

Which Trees Are Most at Risk in Dorset Winters?

All trees carry some wind-failure risk in severe conditions, but some species and situations are higher risk than others:

• Beech (Fagus sylvatica): Shallow-rooted and susceptible to uprooting, particularly in wet ground. Very common in Dorset hedgerows and gardens. Significant specimens should be inspected in autumn.
• Ash (Fraxinus excelsior): Many Dorset ash trees are affected by Ash Dieback, which weakens branch structure and increases failure risk. Diseased ash trees near structures need professional risk assessment before winter.
• Leylandii and large conifers: Evergreen conifers retain their foliage year-round, presenting a constant wind sail. Tall leylandii hedges and trees are particularly prone to wind-throw in Dorset's exposed positions.
• Trees in exposed coastal positions: Properties along Dorset's coast — from Swanage to Weymouth — experience much higher wind speeds and salt-laden winds than inland areas. Trees in these positions warrant particular attention before winter.
