Tips for Controlling the Invasive Tree-of-Heaven

Welcome to Tips Tree Planting, where we share our juiciest gardening secrets with our besties! Today, we’re going to talk about a serious threat to many habitats and untended areas: the invasive tree-of-heaven. Also known as Chinese sumac, varnish tree, or stink tree, this rapidly growing deciduous tree has become a nuisance in the United States. But fear not! We’ve got the tips you need to control and manage this invasive species.

The Tree-of-Heaven: A Sneaky Invader

The tree-of-heaven, originally native to parts of China, was introduced to North America in the late 1700s. Since then, it has spread like wildfire and invaded urban and rural environments across the country. This tree is a formidable opponent, with wind-scattered seeds and the ability to sprout colonies from established trees, creating monoculture stands of the species. To make matters worse, the tree-of-heaven also produces allelopathic chemicals that inhibit the growth of neighboring plants, giving it an additional competitive advantage.

A Challenge to Control

Controlling the tree-of-heaven can be quite a challenge. It can grow up to 80 feet or more, outpacing the growth rate of most native tree species. Female trees produce an abundance of seeds that are easily scattered by the wind, leading to further spread. But don’t worry, we’ve got you covered with some expert tips on how to manage this pesky invader.

Herbicide Options and Application Techniques

In our quest to control the tree-of-heaven, we turn to the experts at Purdue University. Their extension specialists and property managers have developed effective strategies to tackle this invasive species. One of the key methods they recommend is using herbicides.

By carefully selecting the right herbicide and applying it at the right time, you can effectively manage the tree-of-heaven. Purdue Extension offers a free download on their resource center, which provides detailed information on herbicide options, application techniques, and strategies for controlling and managing the tree-of-heaven. You can find the free download on their website, Tips Tree Planting.

Expert Advice for Tree-of-Heaven Control

To gain a deeper understanding of the tree-of-heaven and its management, Purdue Extension’s Forestry and Natural Resources (FNR) YouTube channel is a great resource. They have a video titled “ID That Tree: Invasive Tree of Heaven” that helps you identify this invader and learn more about its characteristics.

As part of our commitment to provide useful content, we have compiled a list of additional resources from Purdue Extension’s FNR YouTube channel and The Education Store. These resources cover a range of topics related to invasive species, woodland management, and tree risk management. You can find the links to these resources in the original article.

So, if you’re dealing with the invasive tree-of-heaven, arm yourself with the right knowledge and strategies to tackle this threat. Remember, at Tips Tree Planting, we’re here to help you create a beautiful and thriving garden, free from the clutches of invasive species. Happy gardening!
