After heavy rainfall in Armadale, WA, you may notice trees tilting or leaning more than usual. As a 4th-generation certified arborist from Arborwise Tree Care, fully insured and experienced in residential and commercial sites, I’ll explain the reasons behind leaning trees, the role of soil and root systems, and when it’s safer to consider removal.
Understanding Why Trees Lean
Trees can lean for several natural and environmental reasons. Recognising the underlying cause helps determine whether the tree can be saved or if removal is necessary.
1. Soil Saturation and Instability
Heavy rain can saturate soils, especially clay or compacted soils common in Armadale. Waterlogged soil loses its strength, reducing the anchoring ability of roots. This often causes previously stable trees to tilt. For minor lean, ongoing tree trimming and canopy management can help rebalance weight distribution.
2. Shallow or Weak Root Systems
Trees with shallow roots or compromised root health are particularly susceptible to leaning. Factors include: poor soil aeration, root rot, previous construction, or damage from storms. Routine tree care can detect early root problems before the tree becomes unsafe.
3. Wind and Storm Damage
Wet soil reduces stability, so even moderate winds can push a tree off balance. If a tree is already leaning, this may exacerbate the issue. Timely tree removal or pruning can prevent property damage.
Signs a Leaning Tree May Be Unsafe
It’s important to assess whether a leaning tree poses a risk. Warning signs include:
- Visible root exposure or lifted soil
- Large cracks in the trunk or branches
- Significant tilt (>15 degrees) or recent rapid movement
- Dead or dying branches indicating structural weakness
When these signs are present, consulting an arborist is critical. Our team at Arborwise Tree Care can evaluate whether tree removal and stump grinding are the safest options.
When Removal Is Safer
While minor leans can sometimes be corrected with bracing or pruning, certain conditions make removal the safer choice:
- Compromised root system or root rot
- Excessive lean threatening structures or power lines
- Dead or diseased trees posing risk to people or property
- Repeated leaning after storms despite corrective pruning
Professional removal ensures safety and avoids property damage. Post-removal, stump grinding clears space and prepares the site for future landscaping or tree planting.
Preventive Measures to Reduce Leaning Risk
Preventive care is the best way to protect your trees during wet weather:
- Regular tree care inspections to assess root and trunk health
- Pruning overgrown branches to reduce wind resistance (tree trimming services)
- Soil management and aeration to improve drainage
- Installing supports or cables on vulnerable young trees
FAQ: Leaning Trees in Armadale
- Why do trees lean after heavy rain?
- Saturated soil weakens root anchoring, making trees more prone to tilting, especially if roots are shallow or damaged.
- Can a leaning tree be saved?
- Minor lean caused by uneven growth can sometimes be corrected with pruning or cabling. Professional assessment is recommended.
- When should I call an arborist?
- Call an arborist immediately if the tree poses risk to structures, people, or if you notice exposed roots or cracks in the trunk. Arborwise Tree Care can provide assessments and safe solutions.
- Does removing a leaning tree require council approval?
- Yes, depending on the tree’s location and significance. Always consult the City of Armadale guidelines.
