The Best and Worst Trees for Mulch

Pine Trees

Fruit Trees

Beech Trees

Beech leaves decompose slowly, creating a dense, moisture-retentive mulch that suppresses weeds and adds organic matter to the soil.



Worst Trees for Mulch

Black Walnut Trees

Black walnut leaves and hulls contain juglone, a toxic compound that can inhibit the growth of nearby plants, making them unsuitable for mulching.

Poison Ivy and Poison Oak

Poison Ivy and Poison Oak: Avoid using mulch from these toxic plants, as contact with the oils can cause skin irritation and allergic reactions.



Diseased Trees

Mulching with materials from diseased trees can introduce pathogens and pests into your garden, potentially spreading disease to healthy plants.

Summary

Choosing the right trees for mulch can greatly enhance the health and productivity of your garden. By selecting trees with beneficial properties and avoiding those with harmful effects, you can create a nutrient-rich mulch that supports plant growth and improves soil health. Remember to consider factors such as decomposition rate, nutrient content, and potential allelopathic effects when selecting trees for mulching, and always prioritise the well-being of your garden ecosystem.
