How to Select the Best Tree for Your Yard
By Rolf Frankenbach, Woodland Tree Foundation board member
Good planning when selecting a tree will reward you with many decades of enjoyment and added value to your home and neighborhood. It is important to think in the long-term about the function of the site so the tree will meet your expectations.
There are many factors to consider when you choose a tree. The checklist includes the tree’s size at maturity; growth rate; disease resistance; compatibility with existing plants; climate; soil; water; nutrient needs; the quantity of litter generated; potential for root damage to structures; and the amount of shade it will provide.
One common mistake is choosing a tree that ultimately outgrows the site. Choosing the right size tree will reward you with many years of enjoyment as the tree reaches its ultimate size and mature beauty. Planting a large tree in a tight area, such as beneath a power line or too close to a structure, can create maintenance problems or property damage. In addition, the tree will probably never reach its beautiful natural form in such a location.
You should also choose a tree that is resistant to common diseases found in Woodland. Tree species that do not acclimate well to Woodland’s climate, soil and water conditions can be more susceptible to diseases. For example, Modesto ash is susceptible to anthracnose, lilac borer and mistletoe. Silver maple has problems with aphids and mistletoe. And Cottonwood trees can develop cankers. Woodland has naturally alkaline soils and our groundwater supply is also alkaline, so avoid choosing a tree species such as Tupelo that requires neutral or acidic soil.
Something else to think about is the amount of shade you want. In the right location, the foliage of a large tree to the south or west of your home can shade your house during the hot summer months, helping you save on energy bills. On the other hand, an evergreen tree planted to the south of a home may prevent winter sun from providing warmth.
Check to be sure that the tree site does not conflict with underground and overhead utilities. You should know the location of underground utilities so that they are not damaged during tree planting. Contact Woodland’s Public Works Department if you are not sure of the location of water, sewer and gas lines. If your tree site is within 15 feet of a power line, select a tree whose mature height will maintain the needed clearance from the high voltage lines. Crepe myrtle is one example of an attractive, small tree that is a good choice for planting under a power line.

Keep these factors in mind when you choose your tree and prepare your planting site. When the planting is done you can sit back, relax and enjoy your tree for years to come.
