Start With a Good Lawn Maintenance Schedule to Prevent Wild Violets
Find the Right Balance with Soil Amendments and Fertilizers
To help your lawn defend against Wild Violet weeds it is important to note your soil's pH and nutrient levels. This measurement of chemical levels in the soil under your lawn can be found by using a home soil test kit. The experts at your local Extension Office can help you interpret the results from this test and make the best decisions from there.
Wild Violet weeds grow best in soil with a low pH level, but most turf grasses thrive with a higher soil pH level. Considering this, you can use soil amendments to adjust the levels of your lawn to discourage future Wild Violet growth and help your turf grow even stronger.
Follow Good Cultural Practices to Keep Wild Violet from Coming Back
Pre-emergent weed killers are rarely labeled for use against Wild Violet because its thick rhizome root network makes chemical prevention difficult. But carefully tending your lawn can offer you another type of defense against Wild Violet weeds.Maintaining a healthy lawn will help your turf grow thick and strong. Hearty turf grasses naturally offer a better defense against invasion by unwanted weeds. Following good mowing practices--including never cutting more than the top third of the blades of grass in one mow--can help encourage lawn health as well.
Keep an eye out for standing water around your lawn. Making sure that you allow for proper drainage from your yard will help avoid the damp spots that Wild Violet and other weeds favor.
Aeration of your lawn can eliminate soil compaction to further improve drainage. This is another health boost for your turf.
The better maintained your lawn, the less likely you are to see Wild Violet and other unwanted weeds among the grass.
