Curious minds often wonder: Why are mulberry trees illegal?

Despite their enchanting allure and succulent berries, these trees have sparked controversy due to their invasive nature and potential threat to local ecosystems.

Governments worldwide have enacted regulations to curb their spread, fearing ecological imbalance and agricultural disruption.

In this article, we will delve into why are mulberry trees illegal in various parts of the United States.

Why Are Mulberry Trees Illegal? The Regulations And Restrictions

No matter how much you want to grow mulberry trees, it’s important to know what kind of mulberry tree you’re planting and what regulations and restrictions are in place to grow them in your area.

Let’s look at why there may be prohibitive laws, local regulations, zoning regulations, and even environmental impact assessments that affect mulberry tree planting.

Prohibitive Legislation And Its Reasons

Many mulberry tree species are restricted for a variety of reasons, including adaptability and invasiveness.

For example, white mulberry trees often cross-breed with red mulberry trees.

This poses a risk to native species.

In addition, toxic sap and unripened berries can also restrict certain tree species.

Avoid legal issues by researching invasive species in your region and selecting non-invasive, or native, species for your garden.

Local Ordinances In Respect To Invasive Mulberry Species

Landscaping practices and mulberry tree removal can also be affected by local ordinances and zoning laws.

Some cities, such as Texas, Nevada, and Arizona, prohibit mulberry tree planting and sale on the grounds of size, impact on neighboring properties, or other criteria.

Contact your local government, nursery, or homeowners’ association to find out if your mulberry tree is allowed.

Environmental Impact

In sensitive or protected ecosystems, environmental impact assessments (EIAs) are required to assess the impact of the introduction of new tree species, such as mulberries, on local flora and fauna, water sources, and ecosystem health.

Local authorities must be consulted and permits or clearances must be obtained to ensure positive environmental impacts and avoid unintended damage.


  • Being Messy: Mulberry trees are often portrayed as messy and difficult to maintain due to their abundant fruit production, but proper pruning and cleaning up can help maintain cleanliness and enjoyment.

  • Being Allergenic: Contrary to popular belief, mulberry trees don’t produce a lot of pollen, and they’re not known to be particularly allergenic. They’re also not known to trigger allergies, and the effects of their pollen are usually short-lived and mild.
