Are you struggling to get rid of pesky ground cover in your flower bed?
It can be frustrating to watch it take over and choke out your other plants. But fear not, there are effective ways to eliminate it without harming your desired flora.
In this article, we’ll explore different methods for killing ground cover, including herbicides and manual removal techniques.
Say goodbye to unwanted greenery and hello to a thriving flower bed!
How To Kill Ground Cover In Flower Bed
One of the most effective ways to kill ground cover in a flower bed is by using an herbicide. Look for a herbicide that is specifically made for vegetation that grows close to the ground, such as glyphosate. This herbicide can be applied using a spray nozzle or a paintbrush for more precise application.
When using an herbicide, it’s important to be careful not to get it on any other plants, as it can kill them as well. Additionally, be mindful of drift and avoid spraying on windy days.
If you prefer a more manual approach, you can remove the ground cover by cutting it close to the ground with a gas-powered weed trimmer. Be sure to wear safety glasses and remove all but 1-2 inches of growth. Rake over the area to remove any remaining pieces and spray the stumps with glyphosate right after cutting them.
It’s important to note that ground covers can sprout from pieces left on the ground, so be sure to clear out as much as possible. After one week, spray glyphosate on any remaining green or actively growing parts of the ground cover.
Once the ground cover is dead, use a hoe to chop out root sections and remove the root base from the flower bed. Rake the area carefully to ensure all remnants of the ground cover are gone.
Identifying The Ground Cover Species
Identifying the ground cover species is an important step in determining the best method to kill it. The first step in identifying the species is to observe the plant during its growing season, which is usually late spring and summer. Note the color, texture, and shape of the leaves and flowers. Evergreen ground covers do not lose their leaves during winter, while deciduous ground covers drop their leaves in fall and die off completely above the soil level in cold weather.
Take a picture of the ground cover for reference during research, and measure the mature height and width of the plant. Measure the width of flowers and leaves to look for distinctive characteristics. Check the available sunlight in the growing location to determine whether the plant thrives in full sun, partial sun or shade or full-shade. This information may be crucial in identifying the species as light requirements may be the most distinctive feature that distinguishes two plants from each other.
Visit an online plant database to browse different pictures of ground covers. Select the search parameter “ground cover” under the plant trait section of the search engine. Fill in other pertinent information to help narrow down the search parameters. Use your notes and snapshot as a reference as you move through the various pictures of ground-cover plants. Remember that many plants produce flowers in different colors, so look beyond flower color during identification.
Another way to identify ground cover species is by using a weed database to ensure that the plant is not a creeping variety. This database allows you to search by distinctive characteristics to narrow down possibilities.
If you are still unsure about the species, cut a full set of leaves and a single flower for analysis by a garden center or local university cooperative extension office. They can help you identify the species and recommend an appropriate method for killing it.
Manual Removal Techniques
Manual removal techniques can be effective for getting rid of ground cover in a flower bed. One such technique involves digging up the ground cover by hand. Start by making a 2-foot trench around the area and loosening the first section of roots. As you dig further into the bed, continue to loosen the soil and pull out as much of the ground cover as possible.
Another manual removal technique involves smothering the ground cover with a black tarp or plastic. Once you’ve manually removed as much of the ground cover as possible, cover the area with a tarp or plastic that will block out all sunlight. Be sure to secure it well with rocks or logs so that no light can get through to the leftover roots of the plant. Leave the tarp or plastic on for at least 6 weeks, but it might be better to leave it on for several months to ensure that all of the roots are dead.
Cardboard can also be used to smother ground cover. Remove any packing tape from large cardboard boxes and lay them on the ground where you’ve manually removed as much of the ground cover as possible. Overlap adjoining sheets by at least a foot to ensure that no new growth can find its way between two pieces of cardboard. Cover the cardboard with about four inches of wood mulch and let it be for a couple of years, adding more wood mulch as needed to keep the area looking tidy. The rain will help the cardboard decompose, and the ground cover will die because of a lack of light and air.
Herbicide Options For Killing Ground Cover
When it comes to using herbicides for killing ground cover, there are a few options available. One of the most popular herbicides for this purpose is glyphosate, which is a broad-spectrum, nonselective herbicide. This herbicide can be used to kill all types of vegetation, including ground cover plants.
When using glyphosate, it’s important to follow the instructions on the label carefully. This herbicide should be applied when the ground cover is actively growing, and it should be sprayed directly onto the leaves of the plant. Be sure to avoid getting the herbicide on any other plants in the area, as it can kill them as well.
Another option for killing ground cover is to use a selective herbicide that targets only grasses. These herbicides are typically labeled for post-emergent control of grasses and can be used to kill grass that is growing in and around ground cover plants.
Some examples of selective herbicides that can be used for this purpose include sethoxydim, fluazifop, and clethodim. These herbicides should be applied when the grass is young and actively growing, and multiple applications may be needed to achieve complete control.
If you have a large area that needs to be treated for weeds, a concentrated solution may be more effective than a ready-to-use solution. BioAdvanced Weed Killer for Lawns is a good option for this purpose, as it can cover up to 20,000 square feet and is rainproof one hour after application.
When using any type of herbicide to kill ground cover, it’s important to wear protective clothing and follow all safety precautions. Be sure to read and follow the instructions on the label carefully, and avoid using herbicides on windy days or when rain is expected within 24 hours of application.
Precautions To Take Before Using Herbicides
Before using herbicides to kill ground cover in a flower bed, there are some precautions you should take to ensure the safety of yourself and your plants.
Firstly, always read the label instructions carefully and follow them exactly. Herbicides can be harmful if not used correctly, so it’s important to understand the dosage and application process.
Next, wear protective clothing, including gloves and goggles, when handling herbicides. This will prevent any accidental contact with your skin or eyes.
When applying herbicides, be mindful of the weather conditions. Avoid spraying on windy days to prevent drift onto other plants. Additionally, avoid spraying during periods of rain or high humidity as this can reduce the effectiveness of the herbicide.
It’s also important to be aware of the proximity of other plants in the flower bed. Herbicides can kill any vegetation they come into contact with, so take care to avoid spraying on other plants. If necessary, use a shield or cover nearby plants with plastic bags or trash bags to protect them from the herbicide.
Finally, be patient when waiting for the ground cover to die. It can take up to two weeks for the herbicide to fully take effect, so avoid pulling up the ground cover too soon. Once it’s dead, remove all remnants carefully to prevent regrowth.
Post-Treatment Care For Your Flower Bed
After successfully killing the ground cover in your flower bed, it’s important to take care of the area to prevent new weeds from sprouting. Here are some post-treatment care tips for your flower bed:
1. Apply a pre-emergent herbicide: To prevent any new weeds from sprouting, apply a pre-emergent herbicide like Barricade in the fall and early spring. This will create a barrier that prevents weed seeds from germinating.
2. Add mulch: Mulch is a natural physical barrier that can deter weed growth. Apply a layer of mulch over the soil to help keep the area weed-free.
3. Regularly weed: Even with pre-emergent herbicides and mulch, some weeds may still sprout. Be sure to regularly weed your flower bed to keep it looking its best.
4. Water appropriately: Proper watering is essential for the health of your plants and can also help prevent weed growth. Water your plants consistently and deeply, but be careful not to overwater as this can lead to root rot.
By following these post-treatment care tips, you can help ensure that your flower bed remains healthy and beautiful for years to come.
