Tree Growing Containers - Cone-tainers Support Tray

The Cone-tainers Support Tray is a durable, long-lasting solution for starting and growing healthy tree seedlings. Designed to hold 98 cone-shaped cells, this tray encourages optimal root development through air pruning—reducing transplant shock and promoting strong, fibrous root systems. Perfect for home gardeners, small farms, and reforestation projects, the tray supports a variety of seedlings including fruit trees, native plants, and ornamentals.

Made from rugged polystyrene, the tray is built to last 8–10 years under regular use, providing excellent value for sustainable growing operations. Its 1' x 2' size is easy to handle in greenhouses or outdoor nurseries, and the rearrangeable cell system allows flexibility in plant spacing and organization. Ample aeration and drainage help maintain soil health and protect against root diseases.
