Plant a Tree for Arbor Day

Plant a Tree blog, 2018

One of my favorite holidays is coming up, Arbor Day. As a tree enthusiast, I appreciate any holiday that urges people to plant trees. Arbor Day is always celebrated on the last Friday of April in Nebraska, this year that is April 27th. This holiday is not the same throughout the United States, it is moved around for other states to be in the best planting time for the year.

Deciding what tree to plant is very important and sometimes difficult. Diversity is key when choosing your tree. The general rule is to plant no more than 10% of a tree species, no more than 20% of a tree genus, and no more than 30% of a tree family in a respective urban area. Look around at what types of trees you have and what types of trees your neighbors have before deciding on a new tree, try to avoid everyone planting the same few trees throughout the neighborhood. Look for some unique, underutilized trees such as gingko, Kentucky coffeetree, Ohio buckeye, hornbeam, paw paw, sweetgum, or tulip tree for deciduous trees that do well in southeast Nebraska.

The most important factor to keep in mind when planting trees is how to plant a tree correctly to ensure healthy growth. First of all, remove all of the burlap and any other materials from the root ball before planting. Also remove any tags, twine, or wire from the tree. Remember to remove all the grass and weeds that are within the area you will be planting the tree. Dig a hole that is 2-3 times wider and no deeper than the root ball and loosen up the sides of the hole. Plant the tree so that root flare is at the soil surface. Do not amend the soil that is in the hole, backfill with the existing soil. Make sure that the entire root ball is covered with soil to avoid drying out.

Keep newly planted trees well-watered. Always water newly planted trees, shrubs, or any other plant immediately after planting. Trees should be watered every 10-14 days throughout the growing season and even some during the winter on warmer days. Each watering should give the tree 1-2 inches of water. The best way to determine if a tree needs to be watered is to insert a soil probe or 12-inch-long screwdriver into the ground around the tree. If it goes in easily there is no need to water, if it is difficult at any point then water is necessary for the tree.

A mulch ring should be established and maintained around every tree. Mulch helps to keep the roots cool in the summer and regulated to a uniform temperature through the winter. Mulch will also help keep weeds down and reduce competition from those weeds for water and nutrients. Mulch also reduces damage to the trunk of trees from lawn mowers and trimmers. Finally, organic mulch is a way to hold moisture for use later by the tree. Mulch rings should be only 2-3 inches deep and in a circle around the tree at least 2-3 feet out. Organic mulches are a better choice than inorganic mulches. This mulch will need to be renewed every year to maintain an effective layer because it will break down over the growing season which will improve the soil.

Tree Planting, 2017 (3)Staking a tree is not a mandatory practice. If you do have to stake the tree due to high winds, make sure that the tree has plenty of movement to allow it to build stronger roots. Also be sure that the staking material is removed after the first year to avoid the tree being damaged by the staking materials.
