The images to the left show quite clearly that over time Defender Tree Shelters, naturally split along the corners, so ensuring that tree strangulation is not a cause for concern as can happen with some other types of tree shelter currently available.

Defender Tree Shelters also have considerably more internal volume which can encourage growth of healthy side shoots. Combined with the soft folded top, reducing the damage caused by chaffing and rubbing of the tree stem against the top of the tree shelter, Defender is the obvious choice when selecting the tree guards for your newly planted tree's.

Due to their physical nature and appearance. Defender tree shelters also make a dramatic difference in terms of transportation from factory to site to most other types of twin walled tree shelters. Defender Tree Shelters fold flat occupying much less space during transportation, thus reducing the number of pallets and ultimately vehicles on the road. This also makes handling much easier for the contractor too who can easily manage to carry bundles of 50 shelters at a time, whereas with cylindrical shelters, they would struggle to carry 15 to 20.

Theoretically, these physical properties also make the recycling of the tree tubes much more viable as the major cost in recycling these growth aids comes from the transportation back to the processing plant at the end of their lifecycle. If they were flat instead of cylindrical, they would stack much better, occupying less space, reducing the number of pallets or vehicles required to collect them, making the cost of recycling a more viable option to landfill.
