After removing the existing bluegrass, flowering ground covers were planted that use less water than a traditional lawn and without all the, mowing, trimming and fertilizing. As the plants mature, they will grow only a few inches tall and about 1-1.5 feet wide to cover the entire soil surface. This type of landscaping may be watered with drip pipe that has the emitters built into it (in-line drip), or efficient overhead spray nozzles that are set less frequently than for bluegrass as these plants like to dry out between watering. Make sure to water a groundcover lawn once a month in the winter to make sure these plants are healthy and ready to grow in spring.
