Executive Tree Care: Safe & Professional
As professional tree care specialists, we carry out all physical work on your trees with the utmost care for crown shape and final appearance, safety, the environment, and tree health. You can contact us for:
✂ Professional pruning: from guidance pruning for young plantings to the safe removal of dead wood or top-heavy branches from monumental trees. We pruning should always be based on the well-being of the tree and the duty of care for nature.
🪚 Felling and dismantling: Does a tree have to go? We removing (dangerous) trees controlled and safe, even in the most difficult to reach or risky locations (such as enclosed city gardens or near buildings).
Storm damage cleanup: In acute emergencies caused by storms, we intervene quickly and efficiently. We secure the area, remove dangerous branches, and then the work begins. professional cleaning up of storm damage, without further risks to your property.
Knowledge base: morphology & physiology as the foundation of our advice
Strong tree management and well-founded tree advice do not start with "feeling", but with how trees functionThat's why we base our analyses and preconditions on tree physiology: water must be able to continue to flow through the tree, the energy balance must allow for recovery, and the root system determines whether a tree can withstand stress or interventions. Understanding this mechanism allows us to make the right decisions more quickly in design, construction, or project planning.
- Energy management in trees – why reserves, growth and recovery capacity determine whether conservation is realistic.
- Water transport and drought stress – how water moves through the tree and why disruption of water availability can cause damage so quickly.
- Tree roots and root systems – not only room for growth and stability, but also cooperation with the soil life: trees send sugars (energy) to the root zone and, through this underground “exchange”, receive water and nutrients back more efficiently, including via mycorrhiza and microbial processes.
Tree technical advisor Bert Janssens holds both the certificate European Tree Technician as the postgraduate diploma Tree Manager and is also QTRA-registered and VOL-VCA.
Why Tree Care and Strategic Tree Advice are the Key to a Climate-Adaptive Future
Trees aren't just decoration; they're complex, living machines that keep our environment livable.
While planting new trees is essential, it is maximum preservation of existing, mature trees the highest priority.
Scientific research (including that of the Nature(group) shows that a single large, vigorous tree can store as much carbon as hundreds of young trees combined. Moreover, mature trees, thanks to their enormous leaf surface area (canopy cover), provide exponentially more cooling and particulate matter filtration.
The tree as a biodiversity hub
A mature tree is much more than a plant; it is a biodiversity hub in the landscape. As a tree ages, its ecological complexity increases. Hollows, cracks in the bark, and dead twigs create unique niches for thousands of organisms.
- Above-ground hotspots: Old trees serve as landing sites, nesting sites, and food sources for birds, bats, and rare insects. They form vital links (stepping stones) in ecological networks.
- Underground network: Through photosynthesis, trees nourish soil life. They supply sugars to a complex web of fungi (mycorrhiza) and bacteria, which in turn maintain soil fertility for the entire environment.
- Genetic reservoir: Old trees have proven their resilience to decades of climatic variations. Their preservation is essential for maintaining strong, local genetics.
Our vision: conservation and tree care through expertise
Tree care at B-Tree focuses on safeguarding this living capital. Our specialized approach ensures that trees continue to fulfill their crucial roles:
- Natural air conditioning: A mature tree evaporates hundreds of liters of water per day. This process extracts heat from the air, which locally increases the ambient temperature by as much as 10°C to 15°C can decrease. This effectively combats the urban heat island effect.
- Water management & erosion prevention: Thanks to their extensive root systems and optimized growing locations, trees act as natural sponges. They absorb stormwater, slow its flow into the sewer system, and prevent soil erosion.
- Biodiversity as a foundation: Trees are "ecosystem engineers." Through photosynthesis, they feed the soil life (mycorrhizae and microorganisms) with sugars. This creates a robust ecosystem that is more resistant to diseases and pests.
- Air quality & well-being: Besides producing oxygen, the leaves capture particulate matter and filter harmful gases. Moreover, the presence of monumental greenery is scientifically proven to reduce stress and promote social interaction.
From design to future tree
At B-Tree Tree Care, we understand that the greatest ecological gain lies in achieving the final result. Only when a tree reaches its maximum size does it deliver its full potential in ecosystem services.
We understand the underground needs for rootable space and the above-ground necessity for proper crown architecture. We provide the right habitat design, a tree protection plan for construction projects, or complex site improvements to revitalize faltering veterans. Only in their mature stages do trees transform into the indispensable biodiversity hubs that underpin our environment.

Integrated tree safety inspection
In tree care, when determining tree safety, knowledge about fungi is essential. Here you see a real honey fungus At the base of a silver birch trunk. The honey fungus is a parasitic fungus that attacks the tree and will soon cause its death. The tree also becomes very susceptible to breakage due to the attack.

Project in the spotlight: saving a monumental beech tree through sound tomography and reduction pruning
The challenge in tree care: preservation versus safety
In the historic avenue of the Pelgrimhof landscape heritage site (Heist-op-den-Berg), a centuries-old beech tree showed worrying symptoms of internal rot at the base of the trunk. While many would opt for immediate felling, we sought a scientifically sound solution to safely preserve this living monument.
The diagnosis: invisible defect exposed
As a certified tree technical advisor, we first carried out a sound tomography This non-invasive technique provided a crystal-clear image of the trunk's internal condition. The results were critical: the base of the trunk was so severely damaged that its susceptibility to fracture posed a direct risk to the surrounding area.
Tree surgeons in action: mechanical crown reduction
To give the tree a second life, we at b-Tree Tree Care opted for a heavy mechanical crown reductionBy strategically reducing the weight and wind resistance of the crown, we reduced the mechanical load on the weakened base of the trunk to an acceptable safety level. Although such an intervention is technically challenging, it was the only way to prevent felling.
Result and vision for the future
Thanks to this customized approach, the beech tree will be preserved as a vital biodiversity hub for bats, rare insects, and fungi. To ensure the avenue's continuity, we will plant three new, climate-adaptive trees this winter. This way, we are building a future-proof tree population that can withstand both drought stress and waterlogging.

Innovative tree care solutions: parking without root damage "the growing place construction"
Often the choice seems binary: get rid of the tree or get rid of the parking lot.
At B-Tree Tree Care, as passionate experts, we look for the third way.
By using pressure-distributing growth-space structures (such as sandwich panels), we create a healthy root zone beneath heavily loaded paving. This keeps the heritage trees (pollard oaks in Langdorp) healthy, while safeguarding the site's functionality.

A day of pruning with b-Tree Tree Care
Providing peace of mind and professionalism are our core values. This is what a typical day at b-Tree Tree Care looks like:
- 06:45 – Departure after strategic preparation
Our day starts early. After loading the machines, there's a final equipment check and briefing. The team then departs for the site. Our early start allows us to avoid rush hour and guarantees punctual arrival at your location. - 08:00 – Safety & Analysis
On site we immediately carry out a Last Minute Risk Analysis (LMRA) We discuss the crown architecture, determine the ideal anchor points, install our climbing lines, and take care of the subsoil. - 10:00 – Expertise in the crown
Our tree care specialists climb to new heights. Using advanced techniques (such as SRT climbing), we prune with precision. Branches are controlled with safety ropes and bollards to prevent damage to your garden or buildings. - 16:30 – A sparkling clean finish
After the work is done, the cleanup begins. Branches are chopped, and the work area is thoroughly cleaned. We won't leave until your garden is in perfect condition. - 17:30 PM – Evaluation & Future
We'll conclude the day with a quality control inspection. Your trees will be safe and healthy again, ready for years to come.
