Development and construction of an air-pruning propagation bench, and its proper use

Julia Walker
"Air-pruning is also highly effective for propagating trees. It increases the “shelf-life” of the plant material, prevents root circling, and increases the success of plant installations because the transplants establish quickly. Using such systems eliminates the need to re-pot as the tree grows, as small plants can be potted directly into large containers. This type of pot causes the plant to develop a dense root ball of tiny white roots filled with carbohydrates, ready to branch out when planted. The root ball may also be more resistant to extreme temperatures. This can greatly increase the survival rate of plant material installed in a restoration project."

Air root pruning to accelerate the growth of Elaeagnus x ebbingei from vegetative cuttings

Teresa Maguire and Raja Harun
The study evaluated the subsequent growth of an ornamental nursery stock species Elaeagnus x ebbingei in 2, 3, 5 and 12 litre pots after being propagated in specialised modules which allow for air root pruning compared with plug/standard liner pot production system which does not.

Effect Of Container Shape on Top Growth and Root Development of Selected Landscape Trees

A study by Hani A. Alzalzeleh
This research study looks at the effect of container type on root development to consider the longer term impact on tree survival potential. The objective is to aid in producing trees without deformed roots that have the potential to grow deep and free of deformity.
