Invasive Plants in Milford
What is an invasive plant?
- An invasive plant is a non-native species that was introduced either intentionally or accidentally into a new ecosystem.
- Some invasive plants are sold in nurseries for their ornamental value while others traveled with people or products.
Why is this harmful?
- Invasive plants have no natural enemies to keep the population from spreading. Local wildlife eat the native plants while leaving the non-native invasive plants to flourish.
- Some such as the commonly found garlic mustard have natural abilities to send out chemicals into the soil that hurt neighboring native plants making them spread out of control.
- Invasive vines such as oriental bittersweet will choke trees and ultimately kill the tree.
- Tick populations thrive under some invasive species such as multiflora rose.
How do I know if there are invasive plants in my yard?
- There are an abundance of resources online that will help you identify invasive plants (see below). There are also plant identification apps that allow you to simply snap a photo of the plant you wish to identify.
What should I do?
- Some nurseries still sell invasive plants, always research before planting, and never buy an invasive plant.
- Invasive plants will cause a major nuisance in your backyard. They will grow out of control if left unmanaged.
How to control?
- Each species requires different types of control. It’s best to research the specific type of invasive plant to find the best way to remove it from your yard.
- In general, there are two types of control, mechanical and chemical.
- Mechanical control includes pulling, digging, cutting, mowing, and covering.
- Chemical control includes the use of herbicides.
