Our 38 and 50 cell plug trays are shipped in the Spring. Please check back this winter to pre-order for spring 2021! Trays consist of 38 or 50 cell plants (2" wide x 5" deep), perfect for deep-rooted natives. Orders ship only when all species in the tray are well-rooted and transit-ready, beginning early May and shipping into June. Our greenhouses are in the Midwest, and due to the challenges of getting all the species in the Mix & Match and Garden Kits transit-ready at the same time, we typically can't ship before early-May. Included with each order are full-color plant tags and our guide, Planting and Caring for Potted Plants.
