Leaving grass around trees can have both advantages and disadvantages, depending on the specific circumstances and the type of trees involved. Here are some considerations:


  • Weed suppression: Having a layer of grass around trees can help suppress the growth of weeds, reducing competition for nutrients, water, and sunlight.
  • Erosion control: Grass can help prevent soil erosion around the base of trees, particularly on slopes or in areas with heavy rainfall.
  • Aesthetics: Maintaining a neat and well-manicured lawn around trees can enhance the overall appearance of your landscape.


  • Competition for resources: Grass and trees have different water and nutrient requirements. Dense grass cover can compete with tree roots for these resources, potentially impacting the health and growth of the trees.
  • Water retention: Grass can act as a barrier, preventing water from reaching the tree roots during irrigation or rainfall, especially if the grass cover is thick or the soil is compacted.
  • Mechanical damage: Regular mowing or trimming of grass around trees can pose a risk of damaging tree roots or trunk if not done carefully.
  • Disease and pests: Certain grasses may harbor diseases or pests that can affect the health of trees.

To determine whether to leave grass around trees, consider the specific needs of the trees, the soil conditions, and the overall maintenance goals for your landscape. 

Some recommendations include:

  • Create a mulch ring: Clear a circle around the base of the tree, a few feet in diameter, and replace the grass with a layer of mulch. This helps conserve moisture, suppresses weeds, and protects tree roots.
  • Provide adequate spacing: If planting new trees, ensure they have sufficient space away from grassy areas to minimize competition for resources.
  • Select tree-friendly grass species: If you choose to keep grass around trees, select grass species that have shallow root systems and require less water, minimizing competition with tree roots.
  • Monitor and adjust irrigation: Ensure that trees receive adequate water, especially during dry periods, by adjusting irrigation practices to account for grass cover and tree water needs.

It’s always beneficial to consult with Professional Tree Removal Melbourne who is knowledgeable about the specific conditions in your area and can provide tailored advice based on your tree species, soil type, and maintenance preferences.
