April 25, 2011 Hort Column


It is finally starting to look like spring and the thought of beautiful flower beds and green grass is becoming more appealing each day.  I do have a lot of work to do in our yard this spring, however.  The snow that I blew off of our drive way always seemed to lay in the same area thus causing a winter haven for Voles and snow mold.  I talked about snow mold last week but am going to talk about aerating our lawns this week and if you like green grass I will even talk about fertilizing.  First off, aerating our lawns, it is good practice to aerate your lawn lightly most every spring but core your lawn every third year.  Coring does two things: it allows the soil to be aerated or breathe and it allows for good placement of fertilizers in the spring, 2 pounds per 100 square feet.  A problem coring creates is the exposing fresh soil to the environment allowing those small weed seeds the ability to grow.  This is not always the case but does happen in plenty of cases.  Talking about fertilizers, there are many good products offered by our local nursery suppliers and to look for products that are higher in Nitrogen in the first set of numbers.  Nitrogen is the first number in the formula, Phosphorus is the second number (needed in the fall more than the spring) and Potash (our soil is quite high in potash).  More next week on fertilizers.
