One of WMU's self watering planters sits in the Deither H. Haenicke Memorial Garden outside the chemistry building. Aya Miller, Editor-in-Cheif Landscape Services at WMU have taken the âteach a man to fishâ idiom to a new level with self-watering planters. Crafted from recycled plastic and carpet, the planters work to retain water and fertilizer, reducing the need to be watered from thrice weekly to once every three weeks. The new planters were manufactured by EarthPlanters and were purchased with help from a grant from the Office of Sustainability. David Prellwitz, a groundskeeper for Landscape Services, and Rhonda Cosby, master gardener, co-authored the grant in 2020.
