Clover weed is an annual and common weed distinguished by its low, broad leaves and purple flower. These weeds are certainly a nuisance to those looking to keep their lawns free of the small purple flowers. While removing the weeds by hand is possible and effective, it is also tedious. With a selective herbicide, however, removing the purple clover weeds is a relatively simple task.
Rinse the garden sprayer if it has been filled with anything other than herbicide.
Fill the sprayer with the selective herbicide that contains the phenoxy-type herbicide, 2,4-D, MCPP and dicamba salt (found in Trimec). A selective herbicide will eradicate common weeds, but not harm grass. Make sure that the herbicide is qualified for "postemergent" instances.
Hold the sprayer 4 to 5 inches away from the clover weeds and generously spray the herbicide directly onto the leaves.
Watch the progress of the removal over a week. If clovers remain, reapply the herbicide and continue monitoring the progress. Re-seed the empty patches to reduce the chances of return.
