It seems to be hitting us a little early this year. Lawn and gardens look a lot like they would in mid to late July not the first of May. We are currently in a abnormally dry period in central Kentucky however, our neighbors in southern Kentucky are already in the middle of a drought.
For me water conservation is of the utmost importance. When watering your lawn or garden take measures to conserve water when you can. For example in the garden use soaker hoses or drip irrigation to deliver the water at the root system where the plant needs it most. Even better cover the soaker hose or drip tape with a nice layer of mulch to help keep the water in the ground.
Generally we want to deliver about an inch of water per week (when Mother Nature is not) to the lawn and landscape materials. Do this in one good soaking and not several little dribbles. The plants will benefit to a greater degree to this type of watering. I like to use spot sprinklers to deliver the water to particular plants and I use a mason jar lid sitting level under the sprinkler. When that jar lid is full you have delivered about an inch of water.
