Landscape Grasses Every Master Gardener Should Know

  Perennial Grasses have many uses in the landscape, including helping to control erosion and adding structural interest to the landscape.   They tend to be very drought tolerant, tough, and seldom will be grazed by deer.  Most grasses are left standing through the winter and cut back in early spring, making room for new growth to emerge.  Some grasses, like river oats, self-seed freely.  Clumps of grasses expand as the plants mature.   Perennial Landscape Grasses Andropogon spp., Bluestem,  Beardgrass,...

Plants readily available in the nursery trade are most likely hybrids or named cultivars of specific...

Options for Autumn Leaf Clean-up

  Leaves float on every strong breeze, covering our walks and driveway just hours after we last cleaned them.  The many different species of trees in our community almost guarantee that we will have a long season of managing fallen leaves and pine tags. Leaves may begin to fall in August or September, particularly when the weather is dry.  And some trees hold onto their leaves until the following spring.  So cleaning up fallen leaves is more of an ongoing...
