Eucalyptus (Eucalyptus spp.) is a genus of plants native to Australia that ranges from tiny shrubs to huge trees. The plants are grown for their aromatic leaves and therapeutic benefits, which derive from the plant’s sticky sap.

Although most yard waste is compostable, Eucalyptus may cause issues for green gardeners who want to compost the clippings or droppings from their Eucalyptus trees or shrubs.

Composting eucalyptus leaves

When eucalyptus leaves are composted or used as garden mulch, they decompose slowly due to their thick, waxy coating, but they emit allelopathic substances that are harmful to plants and soil organisms, polluting the compost or soil.

Eucalypt leaves emit huge amounts of volatile organic chemicals (hydrocarbons), which are both repulsive and harmful to earthworms, thus they should also be avoided in the compost.

It’s crucial to remember that these allelopathic substances don’t effect all plants; they’re selective to some extent, but they will typically limit seed germination and root and shoot growth in many plants.

Citrus, rhubarb, and conifer, walnut, laurel, and yew cuttings can all be composted; any toxicity will degrade in the heap. Shredded woody material decomposes faster, as do fir, eucalyptus, and rhododendron leaves.
