Why Fertilising Your Trees Is Essential

Jan 19, 2025

Fertilising trees is an often overlooked aspect of tree care, yet it plays a critical role in ensuring their health and longevity. Like all plants, trees require essential nutrients to thrive; without them, they can become weak, susceptible to disease, and even pose safety hazards. Understanding soil microbiology and its impact on tree health highlights the importance of regular fertilisation and maintenance.

The Role of Soil Microbiology in Tree Health

Healthy soil is teeming with life. Microorganisms such as bacteria, fungi, and other microbes create a dynamic ecosystem beneath the surface that directly influences tree growth. These microbes break down organic matter, releasing essential nutrients like nitrogen, phosphorus, and potassium that trees absorb through their roots.

Without proper fertilisation, the soil can become depleted of these nutrients over time. Environmental factors such as heavy rainfall, urban development, or poor soil quality can exacerbate this depletion, leaving your trees vulnerable to stress and disease.

What Happens When Trees Aren’t Properly Maintained?

Neglecting tree care, including fertilisation, can lead to several problems:

  1. Nutrient Deficiency: Trees may exhibit stunted growth, yellowing leaves, or sparse canopies when they lack essential nutrients.
  2. Weakened Structure: A lack of nutrients weakens the tree’s overall structure, making it more prone to branch failure or toppling during storms.
  3. Increased Susceptibility to Pests and Diseases: Nutrient-starved trees are less equipped to fend off insect infestations or fungal infections.
  4. Hazards to Property and People: Weak or dying trees pose a significant safety risk, as they are more likely to shed branches or collapse entirely.

In many cases, neglected trees may reach a point where tree removal becomes necessary to prevent potential hazards. Tree removal is a last resort, often avoidable with proper fertilisation and maintenance.

Why Fertilising Your Trees Is Essential & How Arborists Can Help

Qualified arborists play a vital role in maintaining tree health. They can assess soil nutrient levels, recommend suitable fertilisers, and apply mulch to retain soil moisture and enhance microbial activity. Mulch provides nutrients as it decomposes, helps regulate soil temperature and suppresses weed growth, giving your trees the best environment to grow.

The Importance of Preventative Care

Preventative care is always more cost-effective and less disruptive than addressing major tree health issues or storm damage. Regular fertilisation and professional tree assessments can extend the life of your trees, keeping them healthy and safe for years to come.

If your trees show signs of stress or nutrient deficiency, or if you’re unsure about their health, now is the time to act. Contact Frontier Tree Services for expert advice on fertilisation, soil care, and all your tree maintenance needs.
