The last Friday in April is Arbor Day. This year that holiday falls on April 25th. In support of this holiday we should all go out and plant a tree or more than one if you desire, or support an organization that does plant trees if you have no need or space for extra trees in your yard.
When planting trees, utilize diversity. Diversity is planting many different types of trees in an area so that if any new disease or insect comes, it doesn’t wipe out all of our trees. The lack of diversity has been a problem recently with pine wilt in Nebraska. Entire windbreaks are being destroyed in a matter of a couple of years due to pine wilt. Just make sure that whatever tree you choose, is resistant to many of the common diseases we see in Nebraska such as Pine wilt.
Planting a tree correctly initially will ensure its success. Here are the steps to planting a tree correctly:
- Pick a good location
- Plant your tree away from buildings and other plants
- Allow it to grow into the location
- Dig a hole that is 2-3 times wider than the root ball and only as deep as the root ball
- Loosen up the sides of the hole
- Before planting the tree, remove the burlap and wire basket
- Be sure to also remove any tags, twine, or wire from the tree
- Do not amend the soil that covers the root ball after it is placed into the hole
- Plant the tree so that root flare is at the soil surface
- Install a mulch ring around the tree
- At least two to three feet out from the base of the tree
- Only 2-3 inches deep
- 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 within the stakes
- Also be sure that the staking material is removed after the first year to avoid the tree being damaged by the staking materials.
One problem that you might notice now in your landscape, after the winter, is deer damage to your trees and shrubs. Deer can do a lot of damage to a tree over the fall and winter months, especially to a smaller or younger tree. Many bucks will rub on trees later in the fall to remove the velvet from their antlers, which can leave a canker or open area on the tree. They can also do damage to our trees and shrubs when they feed on the buds, leaves, and stems of many different ornamental plants. These twigs are going to have a jagged or torn appearance to them due to the way the deer feed on the plants. Typically the damage from deer to a tree can heal, but it will be a location in the tree or shrub where diseases and insects can enter the plant.
If you notice deer damage to your plants, there is nothing you can do for the tree after the damage has already happened. However, depending on the severity, your tree will probably survive after being damaged by deer. You can help reduce the problem in the future by utilizing an electric fence around your property to keep deer out of your lawn, or by putting up a 4 foot tall fence around each tree in your landscape. Remember to protect any newly planted tree from deer when planting.
