Groundcovers can be an excellent choice for suppressing weeds in garden areas. They can save time and energy spent pulling weeds, as well as reduce the need for chemical control. Find out more about low-growing, mat-forming groundcovers for your landscape.
Types Of Groundcovers to Prevent Weeds
Groundcovers can add a surprising pop of color or texture, differentiate between landscape spaces, provide erosion control, and just plain look good. The best groundcovers to prevent weeds are low-growing, dense, mat-forming evergreens, but there are deciduous choices that work well too.
There are groundcovers for sun, part sun, and shady areas that can provide ornamental beauty as well as outcompete weeds.
Best Groundcover Plants to Prevent Weeds
For best results, first remove all the weeds in the planting site. The areas can be solarized in summer for four to six weeks using clear plastic. For quicker planting, pull or hoe the weeds. Perennial weeds such as dandelions may need chemical control to kill all the roots. Spray about two weeks before planting. Read and follow all label instructions.
Then, incorporate compost to enrich the soil and improve its drainage. The best time to plant is in spring to give the plants time to become established before winter.
Dense evergreens are the preferred groundcover that chokes out weeds. Deciduous groundcovers can work too, if they form a carpet of foliage that prevents the sun from reaching the soil and germinating those pesky weeds. Here are a few of our favorites:
