Weeding and tree pruning

Professional weeding and tree pruning ensure that invasive species are managed correctly and that trees are shaped to promote growth while preventing structural failure. This guide covers everything from typical costs to the legal regulations surrounding nesting birds and protected trees.

What Does the Work Involve?

• Site Assessment: Identifying plant species, assessing tree health, and checking for hazards like overhead power lines or underground services.
• Manual Weeding: Removing invasive plants from beds and borders by hand or with specialized tools to ensure the root system is fully extracted.
• Chemical Treatment: Applying targeted herbicides to persistent weeds (such as Japanese Knotweed or ground elder) using appropriate PPE and safety protocols.
• Tree Pruning: Executing specific cuts such as crown thinning, crown lifting, or deadwood removal to improve light penetration and air circulation.
• Wildlife Checks: Inspecting for nesting birds, bat roosts, or other protected species before any work commences.
• Waste Management: Chipping branches on-site or hauling away green waste to a licensed recycling facility.

Typical Costs

Prices are influenced by the size of the garden, the height of the trees, and how easily a chipper or van can access the work area. If your garden is "landlocked" (accessible only through the house), expect labour costs to increase due to the extra time needed for waste removal.

How Long Does It Take?

• Small Border Weeding: 2–4 hours for a standard semi-detached garden.
• Single Fruit Tree Prune: 1–2 hours depending on the level of neglect.
• Crown Lift/Thinning (Large Tree): 4–8 hours for a two-person team.
• Full Garden Tidy-up: 1–2 full days for overgrown spaces.

DIY or Professional?

General weeding is a straightforward DIY task, though it is physically demanding and requires knowledge of root systems to prevent regrowth. However, tree pruning should almost always be handled by a professional, especially if it involves working at height or using a chainsaw.

Pruning incorrectly can "shock" a tree, leading to disease or unstable regrowth that becomes a hazard in high winds.

Professional gardeners and arborists have the correct insurance and knowledge of British Standard BS 3998 (Recommendations for Tree Work), ensuring the long-term survival of your greenery.

Choosing the Right Tradesperson

• Check Qualifications: For tree work, look for NPTC or LANTRA certifications for chainsaw use and aerial work.
• Insurance: Ensure they hold Public Liability Insurance (minimum £2 million, though £5 million is standard for tree work).
• Waste Licence: Ask to see their Environment Agency waste carrier licence to ensure your garden waste isn't fly-tipped.
• Ask these questions:
  • Are you familiar with the Tree Preservation Orders (TPOs) in this local authority?
  • Will you be removing all green waste, or is that an additional charge?
  • What measures do you take to protect my lawn or flower beds while working?

UK Regulations

• Tree Preservation Orders (TPOs): It is a criminal offence to prune or fell a tree protected by a TPO without council consent.
• Conservation Areas: If you live in a conservation area, you must give the local planning authority six weeks' notice before starting tree work.
• Wildlife and Countryside Act 1981: It is illegal to intentionally damage or destroy the nest of any wild bird while it is in use or being built (typically March to August).
• Waste Regulations: Commercial gardeners must have a waste carrier licence to transport garden arisings from your property.

Common Problems

• Topping Trees: Cutting the top off a tree leads to weak, vertical "epicormic" growth that is prone to snapping.
• Leaving Roots: Weeding without removing the taproot (especially with dandelions or docks) ensures the weed returns within weeks.
• Incorrect Timing: Pruning certain species (like Cherry or Plum) in winter can lead to Silver Leaf disease; they should be pruned in summer.
• Poor Access: Not clearing a path for the gardener can lead to delays and increased labour costs.

Frequently Asked Questions

When is the best time of year to prune my trees?

Most deciduous trees are best pruned in late autumn or winter when they are dormant. However, some species like Magnolia and Walnut should be pruned in late summer to avoid "bleeding" sap, and stone fruits (Cherry/Plum) should be pruned in summer to avoid Silver Leaf disease.

Do I need permission to prune a tree that overhangs my garden?

In the UK, you have a common law right to prune branches that overhang your boundary, but only up to the boundary line. You must check for TPOs first, and you should technically offer the "arisings" (the cut branches) back to your neighbour, though most prefer you dispose of them.

Can a gardener work during the bird nesting season?

Work can proceed, but the gardener must perform a thorough "nest check" first. If an active nest is found, work on that specific tree or hedge must stop immediately until the chicks have fledged.

What is the difference between a gardener and an arborist?

A gardener typically handles soft landscaping, weeding, and shrub maintenance. An arborist (or tree surgeon) is a specialist trained in the biological health and structural safety of large trees, usually involving climbing and heavy machinery.

How can I stop weeds from coming back after they are cleared?

The most effective method is to apply a heavy layer of organic mulch (5-10cm deep) or use a weed membrane covered with decorative bark or slate. This blocks the light required for weed seeds to germinate.
