We have a unique opportunity to shape the vision that future generations will see. The beauty and usefulness of the trees that our children’s children see and how much those trees cost in care and maintenance will be determined by our choices this fall and the planting seasons to come. To help us as a community make well thought out plant choices let’s review the basics.

Avoid planting trees under power lines! It is often difficult to imagine the mature size of a tree. Learn to
Do not plant a tree within 20' of the power lines. A tree that matures at 40 feet or higher should be planted even farther away from the lines.
Let’s respect the streets and sidewalks this planting season as well. Everyone loves a tree lined boulevard. They are breathtaking. They are also expensive to maintain. Trees need lots of room for roots. The roots of growing and mature trees are constantly mining the soil for minerals and water. The first eight feet around a mature tree contain massive roots that taper down to the pipeline roots. In our heavy soils roots are often in the top ten inches of soil and can extend three to five times the diameter of the outer branch spread.
Tree roots will win! Roots expand in diameter as well as length every year. They exert a superhuman amount of pressure against anything they are under or near--sidewalks, streets, driveways or home foundations. The larger the tree, the larger the root system it will have. In a tug of war for space, my money is on the root.
For planning purposes in terms of a square such as a front lawn a 24' x 24' area would be needed for a 12” diameter tree (measured at maturity). Many trees achieve 24-30” in diameter at maturity so plan appropriately or call a certified arborist or licensed landscape designer to help you avoid costly mistakes.
Planning ahead can SAVE you and your community thousands of future dollars. Think of your new trees as an investment with the potential to reward you and others for many years to come. Over the next few weeks we will be reviewing planning, selection, planting and maintenance.
