Spring is here and the most important thing to do if you do not use chemicals on your lawn due to kids or pets is to aerate and overseed.  Spring is also the time for mulching the flower beds, and doing a general yard clean up for the left over branches and leaves.  With the heavy spring rains coming, coupled with left over leaves from the fall now would be a good time to clean those gutters.  The excess weight may cause gutters to break away from your house.
