Poplar Trees Landscapine

Poplar trees landscaping

Poplar trees for landscaping.  Their botanical name is (Populus) or Cottonwood.  They are fast-growing trees and require lots of water.  They are in the Salicaceae or willow family and depending on how much water they receive they can grow up to 1-2 ft. per year.

The bark on young Poplar trees is smooth, white to greenish or dark grey.  The foliage is large dark green in color and turns a golden yellow in fall.  They are deciduous meaning there are no leaves during the winter seasons.  They like water but can tolerate drought conditions once they become well established.

Types of Poplar Trees

There are about 35 types of Poplar trees but the most common one is the Lombardy Poplar.  They will grow up to 80 ft. in height and about 15 maybe 20 ft. in width.

The Columnar poplar is the most common and will grow up to 90 ft. tall in height with white bark. These type of trees are used for border and formal landscape designs.

It is a good tree for the Southwest, however, their root systems are invasive so best to plant them away from water lines, pools, or septic tanks.   It does provide some shade during the hot summer months.

Problems with Poplar trees

As mentioned earlier the root system is invasive they are also susceptible to tree borers.  Their wood is soft making it easier for borers and other insects to dig into the tree.

Caterpillars, Aphids and other insects will invade this tree.  Spraying with a good insecticide will kill these insects at bay.  You will need to use Thuricide to kill caterpillars that are on these trees.  Spraying with horticulture oil during the early spring season will prevent the insect larvae from hatching.

A system insecticide is also another way of killing insects.  This type of insecticide is applied to the surrounding ground.  The root system will take in the insecticide and eventually into the foliage, stems, and branches thus killing all insects…excluding caterpillars.

Another problem is the Slime flux disease.  Read more about this disease right here.
