Chickweed is a type of weed that comes in three common species, Stellaria media, Cerastium glomeratum and Cerastium fontanum, which is better known as Mouse-ear chickweed. Chickweed is a nuisance for gardeners because it is particularly susceptible to unwanted insects and plant viruses. Chickweed seeds are common food in chicken feed and if you have chicken feed with chickweed near your garden, it's possible that chickweed could grow. Chickweed is also an annual weed that spreads with ease if it is not controlled during early growth periods.
Pull the chickweed out of the ground using your hands. Try to get as much of the weeds out of the ground as possible. Wear latex gloves to avoid spreading any plant disease.
Dig near the roots for the chickweed that you have trouble getting out. Chickweed has shallow roots and might require that you use a small shovel or hoe to fully remove the roots of the weeds.
Spray a glyphosphate herbicide in the area where the chickweeds were. You can find such herbicide at your local garden store. Spraying in the early spring will stop the seeds from germinating.
Spray ammonium sulfate over any chickweed that sprouts, making sure to get near the roots. Also, the best time to spray is when there is morning dew still on the chickweed.
Fertilize the soil a week after spraying the weeds. Water the soil two to three times a week. If you see any leftover chickweed it should die as soon as the new grass begins to grow.
