Spring is coming: The good news is there are signs of spring’s arrival and with the gradual increase in air and soil temperatures comes the time to apply a pre-emergent herbicide to control crabgrass on turf areas. However, the timing of that application is critical for effective control of crabgrass and other summer annual grassy weeds. Since the pre-emergence herbicides recommended for crabgrass control actually prevent germinating seedlings from emerging, these products must be applied before crabgrass seeds germinate. Researchers report that crabgrass seeds germinate when average daily soil temperatures reach 57 to 64 degrees Fahrenheit at a 1-inch depth. So, some turf managers have monitored soil temperatures as a method of predicting crabgrass germination and determine the optimum time to apply pre-emergent herbicides. Likewise, the bloom period for forsythia has been used as an indicator for the best time to apply crabgrass control. Forsythia blooms just prior to crabgrass germination signaling the time to apply pre-emergent herbicides.
Crabgrass Pre-emergent will prevent grass seed germination, so overseeding will have to wait until late Summer/early Fall. Additionally, pre-emergent should only be applied to established lawns. Some crabgrass pre-emergent may negatively affect young grass roots.
The following tips are also important for minimizing crabgrass pressure and increasing the effectiveness of pre-emergent herbicide applications:
- Mow cool-season turfgrasses at a mowing height of 3 inches or higher
- Irrigate turf areas deeply and infrequently
- Ensure an even distribution of preemergence herbicides, avoiding skips or misses on turf areas
- Pre-emergent herbicides must be watered in thoroughly to be effective, time application before rainfall or use irrigation to accomplish this important step.

Sonic Wave Tree Decay Detector
Tree Check is designed for arborists and urban foresters as a low cost, simple to use, reliable field tool to detect the likely presence of significant decay, cavity or cracks in standing trees. Used properly it can “see inside the tree” revealing areas of concealed severe deterioration that undiscovered could result in tree structural failure and resultant property damage or personal injury.
The tool consists of two sensors that are connected to an electronic circuit board box by simple telephone cables. The sensors are secured with setscrews on carpenter’s awls that penetrate through the bark and slightly into the tree wood on opposite sides of the trunk. After turning on the device, the user taps the start sensor awl with a light hammer creating a sonic or stress wave traveling through the trunk and at the same time creating an electronic signal to the circuit board box starting the “stop watch” timer.
When the leading edge of the sonic wave arrives at the opposite sensor, it creates an electronic signal to stop the timer. The circuit board box displays both the wave transit time in microseconds and a graphic representation of the waveform itself. The user measures the distance between the sensors, calculates the transit time per inch or centimeter comparing it to an expected transit time for defect-free wood of that species. Longer than expected transit times can be an indication that the sound wave movement was obstructed by internal decay, cavity or cracks.

The Story of Johnny Lexus
Five years ago Johnny was known as the annoying older guy who hung around the waiting area of the Hendrick Auto Lexus dealership in Charlotte and bothered the employees.
After receiving a number of complaints about him, Steve Strickland, the General Manager, invited Johnny into his office. He found out what his employees already knew. Johnny wasn't there to buy a car. He just wanted to have conversations and talk to people.
Steve learned that Johnny had worked in one of the towers of the World Trade Center but he wasn’t there on 9-11 because he had a doctor's appointment. Many of his friends died that day so Johnny and his wife moved to Charlotte for a fresh start.
One day Johnny brought his car to the dealership to get serviced and liked the coffee and atmosphere so much he came back to hang out. Steve told me that in listening to Johnny's story he realized that Johnny wasn’t looking to bother anyone. He was looking for a family.
Instead of telling Johnny to get lost and stay away from the dealership, Steve actually hired him to be part of their customer service team.
"What does he do," I asked?
"Anything we ask," Steve responded. "He does a little bit of everything."
At first the employees weren't happy with Steve's decision. But the more they worked with Johnny and learned his story the more they grew to love and appreciate him. He's become so popular and indispensable to the team and dealership he's now known as Johnny Lexus. No one even knows his real last name. Everyone just calls him Johnny Lexus.
Johnny Lexus has gone from the guy who no one wanted at the dealership to a beloved team member that represents the brand of the dealership... all because Steve Strickland took the team to hear Johnny's story.
It's a great lesson for all of us. Everyone we work with and everyone we meet has a story to tell. I've learned that amazing things happen when we get to know their story.
If you are a leader or member of a team, remember that everyone you work with is bringing their story to work. Your job is to get to know their story. When you know their story you will know them a lot better. When you know them better, you will be less likely to see them as annoying, difficult or negative and more likely to see them as someone who is searching to belong; to matter and to add value.
When you look for the good, and see the good in others you find the good in them and yourself.
Steve took the time to listen and look for the good in Johnny and found it and Johnny Lexus found his family.
