Tree surgery can be carried out at different times of the year — but timing can make a big difference to the health of your trees and the success of the work.
So, when is the best time of year for tree surgery in Surrey?
The answer depends on the type of work being carried out, the species of tree and your specific goals.
Winter: The Best Time for Most Tree Work
Winter is often considered the ideal time for tree surgery.
Why?
- Trees are dormant
- No leaves = better visibility
- Reduced stress on the tree
- Lower risk of disease spread
This makes winter ideal for:
- Tree pruning
- Crown reduction
- Tree removal

Spring: Growth and Early Maintenance
Spring is when trees begin to grow again.
Tree surgery is still possible, but:
- Heavy pruning should be avoided
- Trees may bleed sap (e.g. birch, maple)
Spring is best for:
- Light pruning
- Deadwood removal
- Monitoring tree health
Summer: Controlled Pruning
Summer is a good time for:
- Crown thinning
- Managing growth
- Improving light levels
However, work should be done carefully to avoid stressing the tree during active growth.
Autumn: Preparation for Winter
Autumn is ideal for:
- Removing weak or damaged branches
- Preparing trees for storms
- General maintenance
This is a good time for preventative work before winter weather.

Storm Season: Emergency Tree Work
Tree surgery isn’t always planned.
Storm damage may require:
- Emergency tree removal
- Branch removal
- Safety work
This can happen at any time of year across Surrey, Dorking and Reigate.
Does Tree Species Matter?
Yes — different trees respond differently:
- Some trees should only be pruned at specific times
- Others can be worked on year-round
A professional tree surgeon can advise on the best timing for your specific trees.
Legal Considerations
Before carrying out work, always check:
- Tree Preservation Orders (TPOs)
- Conservation area restrictions
These apply year-round across Surrey.

While tree surgery can be carried out throughout the year, winter is generally the best time for most major work.
