Hand pull the strawberry clover if the infestation is moderate. You may need to dig down to ensure that you get all the roots. Cover the soil where the clover was growing with 4 to 6 inches of organic mulch. Add a fresh layer every year.
Apply an herbicide containing glyphosate to large patches of red clover. The herbicide must be applied to red clover in the seedling stage. Once the plants reach 3 inches in height, the product no longer works to control it. Glyphosate herbicide is non-selective and may damage or kill ornamental plants.
Rid the lawn of strawberry clover by applying a post-emergent herbicide with an active ingredient appropriate for the type of turfgrass in the lawn. Use an herbicide with dicamba or mecoprop on warm-season grasses and any product labeled for the control of clover on cool-season lawn grasses. Apply the herbicide when the strawberry clover is actively growing.
