- 1. Treat the bark like its your skin?
In other words, avoid punctures, bruises, or lacerations as much as possible. Lawn mowers, aerators, weed whackers, are notorious for damaging trees. Some trees with thinner bark such as birch and sycamore are more sensitive to such activities. So keep trees healthy and learn exactly what they need. Also look at how the Emerald Ash Borer has impacted local ash trees.
- 2. Mulch is to a tree as hay is to newborn calf
Can’t get a cozier bed for a tree to rest upon than mulch. Historically trees grew in forests where organic decaying matter was in large supply. Mulch also reduces soil compaction enabling better nutrient uptake. Also, it prevents problems associated with tip #1 by creating a natural barrier between grass and tree.

Information such as how to defend against pests and how to more efficiently absorb nutrients. Still curious, check out this TED talk
Best practices in the industry is a certification with the International Society of Arboriculture (ISA). To find out if a person is certified through the ISA, check out this website and type in the person’s first and last name. These specialists seek to keep trees healthy.
