Many trees are planted for their beautiful fall color, especially in locations where the climate provides reliable autumn weather. I have said this multiple times during extension talks and conversations with submitters to the PPDL, but I seem to have not experienced a ‘normal’ fall since moving to Indiana with how erratic the weather has…Read more about Early Fall Color – A Symptom of Stress[Read More]
When I was a kid, if you’d asked me what my favorite season was it would always immediately be summer. No school, time for playing outdoors, swimming, hiking, and late nights playing flashlight tag.

When transplanting trees, it is important to consider the long-term viability. Since the typical life span of an urban tree is 7-20 years (USDA), proper establishment techniques are very important to decrease this mortality rate. When a tree becomes established, it is much more difficult to correct below ground problems. Root deformations can occur for…Read more about Using Pneumatic Digging Equipment to Correct Root Deformations, Deep Planting, and Compaction on Established Trees[Read More]
Finally, spring has sprung and summer is on its way. The hot days and warm nights are welcome for us, but summer isn’t always so kind to our trees, especially in our urban forest and landscapes. Trees are dynamic living organisms that respond to external stimuli in very strategic ways and each season presents its…Read more about Summer Tree Care[Read More]
There are many age-old, philosophical questions that people have been arguing over for many years. What is the meaning of life? Nature or nurture? Do aliens exist? Should I remove the wire and burlap from B&B plant material? The last question has been debated for many years, with almost everyone having a different opinion. There…Read more about Wire Baskets: Leave them or remove them?[Read More]
Pruning is an important maintenance practice on trees that is discussed a great deal. An essential part of making the pruning cut properly is the ability to identify the parts of a branch. Identification of the branch bark ridge and branch collar are vital to severing the branch in a place that facilitates fast and…Read more about Branch component identification for better pruning cuts[Read More]
After you have decided on the best species and cultivar (right plant, right place!) for a location, it’s time to inspect the plants from the nursery or garden center. What should you be looking for when inspecting trees prior to transplanting into the landscape? Here are a few: Look for structural defects (Fig. 1). Ensure…Read more about Selecting High Quality Plants[Read More]
That “chill-out” time for our landscape is nearing the end and it’s time to think about tree maintenance. An important maintenance task is supplemental fertilization during early spring weather, especially if there wasn’t any type of fall fertilization. Let’s take a look at how a tree uses and gains energy during the year to understand why and when trees need nutrition.
