GRASS For years, I used to vacuum the lawn with a bag lawnmower dumping all the chopped grass into the compost. After a visit to Emmaus Penn., the mecca for organic gardeners, I started leaving the clippings where they lay. A demonstration plot there underlined the benefits of this.
Two years ago the importance of organic lawncare was further strongly underlined. The lawns in our area were being devastated by grubs. The largest organic lawn care company with over 800 customers reported ZERO infestations.
