Question 1

When do you need a tree surgeon, and what should you check?

Accepted Answer

When work is **above ground level, involves a chainsaw, or affects a tree's structure** — because tree work is genuinely dangerous, and because getting it wrong can kill a tree that took decades to grow, or bring it down on something.

**When to call one:**

**Any work requiring climbing or a chainsaw**, which is among the most dangerous work in any industry.

**Removing a major limb**, where the cut position determines whether the wound closes or decays.

**Anything near power lines**, which is a specialist matter and should never be attempted.

**Suspected instability** — leaning, root plate lifting, fungal brackets at the base, cracks or dead wood in the crown.

**Storm damage**, where hung-up or tensioned limbs are extremely hazardous.

**Any tree you cannot reach from the ground.**

**What to check before hiring:**

**Qualifications** — recognised arboriculture certificates, and NPTC chainsaw certificates for the specific operations.

**Insurance, and check the figure.** Public liability of a substantial sum is standard, and you should see the certificate rather than be told about it.

**Membership of a recognised body**, with approved contractor status where possible.

**A written quotation** specifying the work in arboricultural terms.

**Whether they will check for legal constraints** — see below — which a competent contractor does automatically.

**The legal constraints that catch people out:**

**Tree preservation orders and conservation areas**, where work without consent is a criminal offence with unlimited fines. **The obligation is on you**, not the contractor.

**Nesting birds.** It is an offence to damage an active nest, which effectively restricts significant work during the main nesting season.

**Bats**, which roost in trees and are strictly protected.

**The vocabulary worth knowing:** **crown lifting** removes lower branches; **crown thinning** removes a proportion throughout, evenly; **crown reduction** shortens the whole crown to a specified degree; **pollarding** is a repeated management regime, not a one-off.

**"Topping" — cutting a crown back to stubs — is bad practice.** It produces weak regrowth, decay and a more dangerous tree. **A contractor offering it is telling you something.**

Question 2

How close to a house can you plant a tree?

Accepted Answer

It depends far more on soil type and species than on any single distance — and the mechanism people worry about is usually not the one that causes the damage. The misconception. Most people imagine

Question 3

When can you cut a hedge?

Accepted Answer

Technically at any time; legally and ethically, not during bird nesting season — and in many countries it is a criminal offence to damage an active nest, regardless of intent. The legal position.

Question 4

How do you take a cutting, and what are the different types?

Accepted Answer

By removing a piece of stem and inducing it to produce roots — and the type of cutting is determined by how mature the wood is, which in turn determines when you take it and how you treat it. Why it

Question 5

What is box blight, and what should replace box hedging?

Accepted Answer

Box blight is a fungal disease causing leaf drop and dieback in box, and it arrived alongside a second problem — box tree moth, whose caterpillars strip foliage entirely. Between them they have made

Question 6

What is a rootstock and why does it matter for fruit trees?

Accepted Answer

A rootstock is the root system a fruit tree is grafted onto. The scion — the variety you actually want, such as a Cox or a Bramley — is joined to it, and the rootstock determines much of how the tree

Question 7

How far do tree roots actually spread?

Accepted Answer

Much wider and much shallower than the popular image of a mirror-image underground canopy — the great majority of a tree's roots sit in the top 60 centimetres of soil and extend well beyond the
