tree grate A metal, decorative grate surrounding a tree in a paved area, flush with the surrounding paving. These are useful because they facilitate planting trees in paved areas by allowing air, water, etc. access to the tree roots.

tree guying The practice of attaching wires by several methods from a fixed object on the ground plane or below and to a tree a few feet above the ground to prevent the tree from blowing over. This method is usually used for large caliper trees, for clump trees, or for evergreen trees. When it is used for large caliper, single-deciduous shade trees, the wires are attached at about the first branching. Guy wires should always be attached at about the same height to avoid twisting the trunk or the root ball. Guy wires may be held in the ground with short ground level stakes, buried stakes, buried steel plates with eyelets, eyelets fastened in pavement, etc. The guy wires are usually marked with ribbon or PVC pipe to prevent pedestrians from tripping on them. Guy wires may be twisted to

tighten them or they may make use of a turnbuckle. Where wires are attached to the tree they must be enclosed in a bendable protective medium where they are wrapped around the tree to protect the tree from the wire digging into the bark. Guying is not always preferred or necessary. See also tree staking.
