28H Deep Propagation Tray
Maximum Vertical Depth for Advanced Root Development.
The 28H Deep Propagation Tray is the ultimate nursery tool for species that demand significant vertical space and a generous root run. With a substantial cell depth of 120mm and a massive 210cm³ volume, this tray is specifically engineered for nurturing young trees, shrubs, and woody perennials, as well as for transplanting smaller seedlings that require a period of further establishment before final planting.
Innovative Root Architecture
To ensure the health of long-rooted plants, each of the 28 cells is equipped with internal anti-spiral root ribs. These vertical channels direct roots straight downwards, eliminating the risk of circling and ensuring the plant does not become pot-bound. When used in conjunction with a large base tray, the system facilitates superior air pruning, resulting in a dense, vigorous root ball that ensures high survival rates after transplanting.
Industrial-Grade Longevity
Injection-moulded from premium, UV-stabilised recyclable polypropylene, the 28H is built to withstand the rigours of professional nursery use. While designed for a minimum of 10 years of service, many of these trays produced over 15 years ago are still in active use today. This exceptional durability makes it a sustainable, lifelong alternative to disposable, flimsy plastic inserts that frequently end up in landfill.
Key Features and Benefits
Exceptional Cell Depth: The 120mm depth is ideal for tap-rooted species, native trees, and nursery stock.
Effortless Extraction: Each cell features a large 22mm drainage hole, which prevents waterlogging and allows for the easy removal of the plant plug without damaging the root system.
Ergonomic and Rigid: The tray is incredibly sturdy and dimensionally stable, yet it remains balanced and easy to handle with one hand.
Eco-Friendly Choice: By investing in professional-grade, long-life equipment, gardeners reduce plastic waste. At the end of its lifespan, the tray is fully recyclable through most hard-plastic waste streams.
