Century-old trees are living heritage. Whether it is a two-hundred-year-old beech in a Brabant estate or a majestic oak shading a Brussels garden, these veteran trees deserve specialist care. Plumridge Tree Experts has the expertise and the sensitivity that pruning century-old trees demands.
Why century-old trees need specialist pruning
Older trees are not simply large trees. They have unique physiological characteristics that set them apart:
- Reduced vitality: a veteran tree grows more slowly and compartmentalises wounds less efficiently than a younger specimen. Excessive pruning can be fatal.
- Extensive deadwood: large dead limbs are common and can weigh hundreds of kilograms, posing a significant safety risk.
- Cavities and hollows: internal decay is normal in old trees but needs careful assessment to determine structural integrity.
- Ecological value: cavities, loose bark and deadwood are habitats for bats, owls, woodpeckers and countless invertebrates. Thoughtless pruning destroys these micro-habitats.
- Legal protection: many century-old trees are listed as remarkable trees in Belgium’s regional inventories, making unauthorised intervention a punishable offence.
Pruning a century-old tree is not a routine maintenance task — it is a conservation intervention.
Our approach to veteran tree pruning
Thorough assessment first
Before any cut is made, a Plumridge arborist carries out a detailed inspection:
- Visual Tree Assessment (VTA): systematic evaluation of the tree’s crown, trunk and root zone for signs of structural weakness, decay or disease.
- Decay detection: where needed, we use specialist tools (resistograph, sonic tomography) to map internal decay without harming the tree.
- Risk evaluation: we assess the likelihood and consequences of limb failure, considering the targets below (house, path, road).
- Ecological survey: checking for nesting birds, bat roosts and other protected fauna before recommending any work.
Minimum intervention philosophy
Our guiding principle for veteran trees is “as little as possible, as much as necessary”. This means:
- Removing only what is required for safety — large deadwood over targets, fractured limbs, clearly hazardous branches.
- Retaining deadwood that is not a risk — standing dead branches in the upper crown are valuable habitat.
- Avoiding large pruning wounds — veteran trees heal slowly, and large wounds invite further decay.
- Considering propping or bracing as an alternative to pruning, supporting heavy limbs rather than removing them.
Specialist climbing techniques
Century-old trees often cannot bear the weight of an aerial platform on their root zone. Our arborists use:
- Free-climbing with modern harness systems to minimise loading on branches.
- Controlled rigging to lower heavy deadwood safely without shock-loading the tree.
- Hand tools for smaller cuts, reducing vibration damage to aged wood.
Types of century-old trees we care for
In the Brussels region and Walloon Brabant, we regularly work on:
- European beech (Fagus sylvatica): the dominant species in many estates, prone to bracket fungi and large limb failure in old age.
- Pedunculate oak (Quercus robur): extremely long-lived but develops heavy lateral limbs that may need support.
- Horse chestnut (Aesculus hippocastanum): often planted in avenues, increasingly stressed by the leaf miner moth.
- London plane (Platanus x hispanica): common in parks and squares, capable of reaching huge dimensions.
- Sweet chestnut (Castanea sativa): frequently hollow but structurally sound — cutting these down is almost never necessary.
- Lime (Tilia spp.): historically pollarded, now often abandoned and in need of careful re-management.
Regulations protecting century-old trees in Belgium
Belgium’s regions have strong protections for heritage trees:
- Brussels-Capital Region: trees listed on the Remarkable Trees inventory require a specific permit for any pruning. Planning permission is also needed for standard trees (circumference > 40 cm at 1.50 m).
- Walloon Region: the Code du Développement Territorial (CoDT) protects notable trees and hedgerows. Permits may be required for significant interventions.
- Flemish Region: heritage trees can be protected under the Onroerend Erfgoed regulations.
- Nesting period: works disturbing nesting birds are prohibited 1 April – 15 August across all regions.
Plumridge navigates these regulations on your behalf, ensuring full compliance and handling permit applications where needed.

Frequently asked questions
Is it safe to prune a very old tree?
Yes, provided the pruning is carried out by a specialist using a minimum-intervention approach. Excessive or unskilled pruning can seriously harm or kill a veteran tree. Plumridge arborists are trained specifically in veteran tree management.
Can a hollow tree be safe?
Absolutely. Many hollow trees are structurally sound because the outer shell of living wood provides strength, much like a pipe is stronger than a solid rod. We assess the wall thickness to determine safety.
Do I need a permit to prune my century-old tree?
If the tree is listed as remarkable or has a circumference exceeding 40 cm, a permit is likely required in the Brussels-Capital Region. In Wallonia, the CoDT may also apply. Plumridge checks this during the assessment.
How often should a century-old tree be inspected?
We recommend a professional inspection every two to three years, or immediately after a major storm. Early detection of defects is key to managing risk while preserving the tree.
