Invasive Plants in Zone 7: A Guide for Gardeners

Invasive plants are a major problem for gardeners, as they can quickly spread and take over an area, crowding out native plants and disrupting ecosystems. Zone 7 is home to a number of invasive plants, so it’s important to be aware of them and take steps to avoid planting them in your garden.

What are Invasive Plants?

Invasive plants are non-native species that have been introduced to an area and have become a threat to the local ecosystem. They are often aggressive growers that can quickly spread by seed, root, or stem fragments. Invasive plants can outcompete native plants for resources such as sunlight, water, and nutrients, and they can also alter the soil chemistry and pH levels.

    • Morrow’s honeysuckle

Problems Caused by Invasive Plants

Invasive plants can cause a number of problems in your garden, including:

  • Crowding out native plants
  • Reducing biodiversity
  • Altering soil chemistry and pH levels
  • Blocking sunlight and water from reaching other plants
  • Attracting pests and diseases

How to Avoid Planting Invasive Plants

The best way to avoid planting invasive plants in your garden is to research the plants you’re considering planting and make sure they are not invasive in your area. You can also contact your local extension service or nursery for a list of invasive plants to avoid.

Controlling Invasive Plants

If you already have invasive plants in your garden, there are a few things you can do to control them:

  • Manual removal: This involves digging up the plants by hand or using a hoe or shovel.
  • Chemical control: This involves using herbicides to kill the plants.
  • Biological control: This involves introducing natural predators or pathogens to control the plants.

It’s important to note that controlling invasive plants can be difficult, so it’s best to prevent them from becoming established in your garden in the first place.

Conclusion

Invasive plants are a serious threat to our gardens and ecosystems. By being aware of the invasive plants in your area and taking steps to avoid planting them, you can help to protect your garden and the environment.
