Session Title:  Effectively Using Air Pruning Systems in Propagation and Nursery Production

Description:  On Demand

Description:  Air-pruning propagation trays and containers can help to develop high-quality tree root systems. With the variety of products available - with features ranging from simple drainage holes, holes or slits in walls to fully wall-less and bottomless containers - how do you decide which container to choose and then how do you manage plants in these types of containers? In this session, we will explore how to effectively use air pruning containers to create high quality root systems in woody perennials. Topics will include: moisture management in air pruning systems, what to look for when choosing a substrate, and discussion about the different features of container types on the market.

Session Title: Field Nursery Soil Health – New Research and Resources

Description:  On Demand

Description:  The impact of different cultivation practices currently used by field nursery tree producers has not been evaluated to understand their efficacy for improving soil health, tree growth, or reducing production costs. In this session, we will explore the soil management practices of field nursery producers including investigating the state of the industry in Ontario, Canada with respect to the current soil health/management practices being employed. We will also describe promising short- and long-term management practices to improve soil properties for tree production. Finally, we will provide an overview of the findings soil management trials we are piloting with nurseries which are aimed at developing practices to improve soil health.

Building sustainable landscapes

The establishment and survival of plants and trees to improve environmental performance, counter climate change pressures while increasing the competitiveness of the nursery landscape sector is the foundation of Vineland’s greening the landscape research program.

Working with partners across Canada, Vineland develops models and specifications to improve the performance of vegetation and green infrastructure design to ensure impact for the industry. 

Innovation Challenge and Opportunity

Plants are the fundamental components of a living green infrastructure that delivers environmental, economic and social benefits. Cities recognize plants and trees as integral to climate change mitigation strategies and have set ambitious canopy cover targets.

Research and the application of that research to understand plant stress tolerance to extremes can inform plant selections and developing tools and production methods is improving plant establishment and survival. Providing clear, industry-ready recommendations backed by solid science and validated methodologies helps the sector capture a market opportunity to engage with cities, developers and others to deliver on climate change targets.
