Squirrel Damage or Oak Wilt: Can you tell the difference?

You may have noticed a lot of squirrel action in your trees lately. This is the time of year that squirrel damage is at its most extreme. They are busy readying their nests for the upcoming winter and foraging for nuts to stash away. Unfortunately, all that work they do to survive takes it’s toll on your large shade trees. Often though, you might mistake squirrel damage for oak wilt, or vice versa. So let’s break down the differences:

Summer: Time to Prune Your Oak Trees

Ever wonder why we avoid pruning oak trees in spring? Spring is prime time for oak wilt disease to infect your trees; pruning oak trees in spring significantly increases chances they'll become infected. With the heavy population of oak trees across Dallas and Fort Worth, the last thing we want to do is add to this growing problem. So, we typically stop pruning oaks in early February and wait until July to start back up.

Is Ivy Growing Up My Tree a Bad Thing?

We are often asked “Will ivy growing up the trunk of my established tree harm it?” Yes and no. Generally, ivy will not harm a healthy, established tree. However, ivy growing around the base of a tree and up its trunk could be competing with nutrients, sunlight and water that the tree needs. This could cause the tree to weaken and become more prone to pests and disease.

Is this Oak Wilt Disease or Normal Leaf Drop?

Now is the time of year arborists are on the lookout for Oak Wilt disease. This destructive disease can kill a large established oak tree in a single season! However, normal leaf drop in live oaks this time of year can often be confused with oak wilt disease.

What’s All the Stress About? Could Be Aphids!

This month, we’re noticing many new insect infestations on trees around the DFW area. Because many of our urban trees are stressed from heat, improper watering and lack of fertilization, they are more susceptible to pest problems. Aphids are one of those pests invading trees right now, as seen on the leaves of the post oak (in photo) that we recently inspected.

Monterrey Oaks: Shade solution that is less susceptible to oak wilt!

Who doesn’t love an oak tree? Take a glance around the Dallas/Fort Worth area and you’ll be hard pressed not to see a live oak in your sightline. Problem is everyone plants live oaks. And while live oaks are beautiful and useful shade trees, we’ve created what could be considered an oak mono-culture. We also tend to plant a lot of red oaks, creating the same lack of diversity.

Fall Oak Wilt Treatment

Oak Wilt is an especially insidious disease that is easily transmitted and can kill a tree in a single growing season. It affects mostly Live Oak and Red Oak trees. Caused by the spores of a fungus, it is carried from tree to tree by small beetles that feed on tree bark. It can also be introduced to a healthy tree by using unsterilized tools that were previously used on an infected tree. A rapid yellowing of the outer leaves near the top in mid-late spring is an indicator of this disease.

Problem is, poor "cheap" pruning can permanently ruin the look of your valuable trees and often leave them susceptible to storm damage, disease and ultimate decline. Here are five of our top common pruning and trimming mistakes we see on trees around the DFW area.

With plants putting on a flush of tender spring growth and the cool moist weather conditions, you’ll need to be on the watch for fungal leaf spots, canker diseases and fire blight. The current environmental conditions are perfect for bacteria and fungi to reproduce and easily find a home within the foliage moisture of tender young leaves.

Live Oak Leaf Drop

While there are a number of problems that can cause leaf drop in Live Oaks, this time of year you’re most likely seeing a normal senescing, or dying off, of last year’s foliage. As temperatures begin to rise in late January through February, your Live Oaks can begin to look sickly or stressed. Leaves begin to yellow and may have brown or black blotches. They will often discolor very quickly and begin to drop en masse.
