“John spent lots of time and energy helping me come up with the right concept for our small garden and the correct utilization of the space. This included finding the appropriate plants and moving established plants and shrubs around to give us optimal viewing from our deck and porch. Throughout the project, John and Martha made us feel like our small garden was the most important thing they could be doing.  Their focus on making us happy while keeping us real and grounded is paying off. We can’t wait until spring!”  – Ingrid & Peter B.
