10. What is the Difference Between Tree Management and Tree Maintenance?
29. To Manage Trees you Need to Start With Answers to Some Basic Questions: What do we have? How many trees? What species are they? What condition are they in? Why are they being pruned?
30. How Much Does Tree Maintenance Cost? There are a few things you need to know: How much to annually contribute to a tree reserve fund? How much to annually budget from the reserve fund for maintenance? Why a reserve fund instead of a budgeted line item?
31. What’s wrong with most community management plans? Usually not a plan, but a prescription for over-pruning that is costly for both the community and the trees. Although easy to remember this does not address the real needs of the community and is damaging to the trees.
40. Trees have leaves for a reason: Leaves produce the energy the tree needs to grow. Energy (carbohydrates and sugars) are stored as reserves. Energy is the tree’s money and stored energy is it’s retirement account.
41. They are called leaves for a reason… Leave Them Alone! Leave Them On The Tree!
42. Why is turf harmful to trees? Out competes trees for water Reduces tree vigor Results in damage to trees from maintenance equipment
43. Why remove ground cover? Prevents inspection of the root collar of the tree Can conceal defects like decay or circling and girdling roots Increases moisture on the lower trunk by shading Can lead to disease or fungus problems
44. Is a root collar inspection really necessary? YES! The root collar is the most critical part of the tree to evaluate for vigor and safety. GOOD! BAD!!!
