Tyler HesseltineAccording to the USDA, August is National Tree Check Month, and Minneapolis has an estimated 400,000 trees. Now is a great time to take a few minutes to check trees for invasive pests, diseases, and potentially dangerous branches in our yards and neighborhoods.

We talked to Arborist Tyler Hesseltine about things to check during August. He is a Board-Certified Master Arborist and a certified Tree Risk Assessment professional, so he really knows trees! Here are Tyler's tips for assessing your trees, along with other info: 

5 Steps to Checking Your Trees

1. Inspect the canopy.

· Removing dead, diseased, or unsafe branches helps trees keep a safe structure and tolerate high winds.

· Clean up unsafe, broken or hanging branches by pruning… but keep your feet on the ground! Any pruning that cannot be managed from the ground should be handled by a certified arborist.

2. Look for signs of heat stress.

· Look for wilted, drooping, or curling leaves with brown edges; premature fall color or early leaf drop.

· The fix? Water deeply and slowly in the mornings; about an inch of water is good for mature trees.

· Mulch also helps reduce moisture loss and regulate soil temperature.

3. Check for pests and diseases.

· Check the leaves for chewing, discoloration, or egg masses.

· The bark or trunks may show signs of holes, oozing sap or resin, or tunnel-like patterns.

· For diseases, frequent signs include dark spots, odd colors or a distorted shape on your trees’ leaves.

4. Fertilize.

· Apply a slow-release fertilizer to help keep trees nourished all season long. Come next spring, your trees will be blooming and ready to show off.

5. Protect & Brace.

· Cable or brace weak limbs before colder weather rolls around.

· Identify the areas of concern, then reach out to an arborist for a solution that will protect the tree in high winds and storms.
