How to Prepare Your Trees for Emerald Ash Borer Season

Emerald ash borers are becoming an ever more severe problem for homeowners in the greater Denver area. They infest trees quickly and can lead to premature death in a matter of months depending on the age and health of the trees on your property. As non-native insects, they have no significant predators to keep their spread in check, so finding ways to get your trees ready for their return in spring is an absolute must. Here are a few easy ways to better protect your trees.

Stay on Top of Watering
Watering in the winter months can help prepare your trees for a stronger growing season in the spring. On warm afternoons when temperatures are above 40 degrees Fahrenheit, water your trees thoroughly. Take care to make sure the water is soaking into the soil and not running off away from the roots. That runoff can strip nutrients from the soil and leave your trees worse for wear come spring. 

You won’t have to water every week. Pay attention to the moisture levels in the soil and water your trees once the soil feels dry. For most homeowners, this means watering once or twice a month until the weather warms up.

Spread Fresh Mulch
Mulch is one of the most useful tools homeowners have when maintaining their landscaping, but it does break down over time. Add a fresh layer of mulch around your trees to protect them from emerald ash borer infestations. You’ll want that layer to be deep—about four inches in depth—and wide enough around the tree to adequately cover the roots and protect the root system beneath the soil. If you’re not sure how much to spread or which type of mulch to use, let your plant health care team help you figure out the best option for your yard’s soil type.

Keep in mind that you’ll need to add fresh mulch anytime the current layer gets thin or starts to break down. If you notice the mulch changing color, it’s likely time to add more mulch to your trees.

Protect Your Trees This Year
Emerald ash borers are becoming more common, but as long as you follow these tips, you’ll be better equipped to protect your trees from infestation. Keep in mind that these are just a few ways to keep your trees healthy.
