Trees are long-lived plants that provide the greatest long-term impacts to our gardens, the landscape, and the environment.  They provide shade, habitat, structure and screening. Some may also provide Spring flowers, Summer fruit and/or Fall foliage. Installing new plantings and maintaining old gardens within the shade and root zone of mature trees can present challenges for the trees and companion plantings alike.  Misunderstandings about mature trees and their roots can impact the health of prized older trees.  Grass and other plantings can decline under increasing competition for light and soil space with trees.  Drawing from decades of experience and expertise, Christina will share some cost-effective techniques to improve the long-term success for all plants in these landscape situations.

All are welcome to attend this event; since space is limited, please RSVP to deborah.sherwood@snovalleygc.org. Attendance is free for club members; a suggested donation of $10 for guests will be collected at the door.
