When it comes to fallen leaves in the garden, everyone has their own method. Some prefer to leave them on the ground, others use them for compost, or to make an effective mulch as winter approaches, or to prepare potting soil. Finally, some people prefer to get rid of them for good, but beware: burning these green waste items is illegal and can result in a fine.
Which Leaves Should Not Be Put in the Compost?
For those who choose to add fallen leaves to the compost, this is indeed a good option since these leaves are rich in nitrogen and carbon. As they break down, they feed the soil and help promote the healthy growth of plants in the garden.
However, not all fallen leaves belong in the compost; certain varieties can jeopardize the quality of the finished compost due to potential diseases or compounds present in their composition. Here are the ones to watch for:
- Cistus leaves, whose allelopathic compounds linger in the compost and subsequently hinder the healthy growth of plants.
- Walnut leaves, whose juglone interferes with the germination of other plants.
- Laurel, plane tree, or privet leaves, which are so thick that they prevent water from penetrating the soil properly and take a long time to decompose.
- Leaves from roses and fruit trees, which are more prone to infestation. It is possible to compost them, however, by carefully inspecting them first to ensure they do not show spots or other signs of disease. Likewise, avoid composting leaves from vegetable plants, which are more susceptible to blight.

What to Do with Leaves and Other Green Waste That You Can’t Put in the Compost?
While most green waste can be put to good use in the garden, particularly for mulching, a question arises: what should you do with these leaves that are better left out of the compost? Since burning is not allowed due to pollution concerns and fire risk, the main option is the local transfer station or recycling center.
Most municipalities provide access to a free transfer station upon proof of residence. Transfer centers that accept green waste have a dedicated area designed specifically for its collection. To find the nearest transfer station that accepts green waste, visit the site MonServiceDechets.
