More Information About Invasive And Native Plants

Invasive plant species can be found in just about any landscape these days.  Do you know which plants are invasive?  If you need help with this, you could schedule a personal consultation, or ask Dr. DeJaco to come speak to your group and teach you how to identify them.

Or, you could go to websites like these that have lots of useful information!

Dealing with invasive plants

The most important thing to do is to try to prevent them from spreading further!  Do this by preventing the release of seeds--   cut off all the flowers and fruits and put them in the garbage so they will be sent to and covered deeply in the landfill.

When removing invasive plants, it is important that you remove or kill the roots of the plant.  If the roots remain alive in the soil, then the plant can keep sprouting back over and over again!  Once you have removed the roots from the soil, make sure they do not touch soil again, or they may actually re-root themselves and grow back.  You can put them in the garbage, or simply make sure they die.  I accomplish the latter by either spreading them out on a concrete surface or hanging them up in other vegetation to ensure the roots will dry out and die. 

The native plant species you put in your yard should be dictated by several factors, for example, the ecological zone are you in, whether the area you want to plant is in the sun or shade, and if the area is at the top of a hill, the bottom, or on a slope.

There are many good groups out there from which you can learn a great deal.  The N.C. Native Plant Society is a very active, friendly group of folks.  Another one of my favorites is Pollinator Friendly Yards.

Here are some other resources from which you can learn about the plants native to your area:

The N.C. Extension Gardener Plant Toolbox

The Lady Bird Johnson Wildflower Center

The Biota of North America Program

Obtaining and using native plants in your landscape

There is now a "For the Birds and the Bees" native plant nursery!  

There are often a few cultivars of native plant species for sale at your local garden center, but you may need to search a bit more to find native plants for your yard.  Here are some of my favorite places from which to purchase native plants:

Your local Native Plant Society probably has plant sales.
