Autumn is the perfect time of year to give your garden some attention and, while you’re tidying borders and clearing fallen leaves, it’s also worth checking for common tree problems.
Changing weather, strong winds, and heavy rainfall can expose existing weaknesses, while certain tree diseases become easier to spot as the seasons change. Identifying common tree problems early can help protect your garden, property and the people around you.
Here are five tree problems in autumn to look out for, plus advice on when to call in a professional.
1. Dead or damaged branches
One of the most common tree problems to watch for during autumn is dead, damaged, or weakened branches. As deciduous trees lose their leaves, their structure becomes easier to see, making it a useful time to spot potential hazards.
Look out for:
- Branches that are brittle, broken, or hanging unusually low
- Cracks where branches join the main trunk
- Branches that have snapped or become caught in neighbouring trees
Dead or damaged branches can fall unexpectedly, particularly during autumn and winter storms. If a tree overhangs your home, driveway, garden path, or a public space, it’s important to take potential risks seriously. A professional tree surgeon can assess the tree and determine whether pruning or other tree surgery is needed to make it safe.
2. Fungal growth and signs of decay
Autumn’s damp conditions can make fungal growth more noticeable. While some fungi are harmless and play an important role, others can indicate decay within a tree’s trunk, roots, or branches.
Look out for:
- Bracket-shaped fungi growing on the trunk or around the base
- Mushrooms appearing near the roots
- Soft, crumbling, or damaged wood
- Areas of bark that look unusually wet or discoloured
Fungal growth doesn’t automatically mean a tree is dangerous, but it shouldn’t be ignored. As decay can affect a tree’s structural strength, it’s best to arrange a professional assessment if you notice unusual fungal growth or other signs of deterioration.
3. Tree diseases and unusual leaf changes
Although falling leaves are a normal part of autumn, changes in leaf colour, condition, or timing can sometimes indicate common tree problems.
Tree diseases, including ash dieback, can affect a tree’s health over time. Spotting symptoms early may help you understand what action is needed to manage the problem and assess any associated safety risks.
Look out for:
- Leaves turning brown or yellow unusually early
- Dead or dying shoots at the ends of branches
- Dark lesions or unusual marks on the bark
- Branches dying back from the crown
Remember that different tree species naturally shed their leaves at different times, so one symptom alone isn’t enough to diagnose a disease.
If you’re concerned about your tree’s health, seek advice from a qualified professional rather than attempting to identify or treat common tree problems yourself.
4. Storm damage and unstable branches
Autumn often brings stronger winds and heavier rainfall in Colchester. These conditions can put additional pressure on trees, particularly those that already have structural weaknesses or damaged roots.
Wet ground can also affect a tree’s stability, making it important to check for changes following periods of bad weather.
Look out for:
- A tree leaning more noticeably than before
- Exposed or disturbed roots around the base
- Large branches that have split or broken
- Soil that appears to have lifted or moved
A sudden change in a tree’s position, a split trunk, or significant root movement could indicate an immediate safety concern. Keep people away from the affected area and contact a professional tree surgeon promptly.
5. Pests and signs of insect damage
Autumn is also a great time to look for signs of pest activity. Although some insects become less active as temperatures fall, damage caused earlier in the year may become more apparent as trees lose their leaves.
Certain pests can weaken trees, damage foliage, or contribute to declining health, so it’s worth investigating unusual symptoms.
Look out for:
- Holes or tunnels in the bark
- Unusual cracks or areas of bark damage
- Sticky deposits or discolouration on leaves and branches
- Unusual insect activity around the trunk or branches
Not every hole, mark, or patch of discolouration indicates a serious infestation. However, if you notice several symptoms together or your tree appears to be deteriorating, a professional assessment can help find the cause and identify next steps.
