As my trees have grown larger, the grass growing under them is becoming thinner and thinner. Are there ground cover plants which I could plant in these shady areas?
There are several ground cover plants which will grow in areas too shady for good grass growth. Ground covers can become invasive and grow into areas where you do not want them. So avoid ivy, Bishop’s Weed and other aggressive ground covers. Plan to spend time with a line trimmer confining them to the areas where you want them to grow.
Ground covers are more expensive to establish than a lawn but save the time and expense of lawn mowing. I suggest using a weed preventer such as Preen to reduce weed problems between plants as they are getting established.
Sweet Woodruff (Gallium odoratum) grows about 3 to 4 inches high and produces tiny white flowers in the spring. It is also drought tolerant and is very resistant to weed invasion once established.
