Garden Design and Garden Installation in Hudson, NH. On the first day of this garden project in Hudson, NH, the crew from Greenleaf’s Garden Design pulled out all the unwanted plants and then started moving in the “Garden Mix Soil”. The Dingo moved the 9 yards up the hill to the sun garden and then to the lower shade garden.. The sun garden has 90 perennials while the shade garden just required 50 perennials. We set up a drip irrigation system for each garden.
