THE AGRONOMIST
The Agronomist: Want To Improve Your Lawn Services? Become a Horticultural Detective!
BACK BEFORE I JOINED NALP, I SPENT QUITE A BIT OF MY time training new lawn specialists. That includes teaching problem- solving, a proficiency that takes a very long time to master. While it is very true that some of the problems we encounter in caring for turfgrass are pest-related, many times, the problems are due to the customer’s irrigation system. Here’s an example.
I was spending this particular

day with a new lawn specialist, teaching this young man how to spray with a ChemLawn gun. We were at a beautiful ocean- front home in Maine where, coincidently, the gardener was busy deadheading and weed- ing in the ornamental beds. He decided to strike up a conversa- tion (or, more accurately, strike up an argument) with me about an off-color area of the lawn and how it must have been burned by fertilizer or herbicide. If I had a nickel for every time I’ve been accused of burning a lawn, I’d be a very rich man indeed. Now, when it comes to
burning a lawn, most of the time it’s pretty obvious in that the entire lawn is involved, not just a small section, as was the case here. This lawn was very healthy except for the half-moon-shaped area along one of the ornamen- tal beds. It appeared dry to me, which made me want to check out the irrigation system. “No, it’s not dry! There’s an
irrigation system here!” was the
retort from the gardener to that observation. Time to run the irrigation
system through a manual cycle and observe each sprinkler head and how it was functioning. The gardener was growing more annoyed with me as I stuck irri- gation flags in the lawn where, in a regular pattern, sprinkler heads popped up. Sure enough, right in the middle of the brown area, there was a break in the pattern. Where there should have been a sprinkler head, there wasn’t one. Or was there? I paced off the distance from the adjoining head and suddenly I stepped in some mud.
A clue! A smoking gun! Or,
more accurately, a muddy spot! I felt like Sherlock Holmes, or maybe since I looked a little rumpled, Lieutenant Colombo. Being a horticultural detective is a lot of fun! With a little digging, I found the missing sprinkler head buried under some overgrown turf. The look on the gardener’s face was priceless! All the chuckling aside, the problem-solving aspect of our job could very well be the most important. From accurately articulating the many environ- mental benefits of turfgrass to distin- guishing between a broken sprinkler head and fertilizer burn, this skill set brings considerable value to

our services. So you must be wondering, how do I become a lawn detec- tive? My advice is to become a student of the craft. Subscribe to as many industry magazines as you can get your hands on, in- cluding those in both the sports turf and golf course industries. Find the social media accounts of turfgrass researchers and edu- cators and read them religiously. Start a library of horticultural books, not just about turfgrass- es, but trees, shrubs, diseases, insects, and weeds. Especially weeds. I’ve been collecting horti- cultural books since I bought my first textbook in college. Some books I purchased, others were given to me, including a first-edition copy of Rachel Car- son’s “Silent Spring” and a nearly complete set of the International Turfgrass Society Research Jour- nal (great for insomnia!). Podcasts are also a fantastic source of information. What I particularly like about podcasts is the casual nature of the conversation be- tween host and guest, giving it the feel of sitting around a table and having a beer while talking turfgrass.
None of this is cheap, not in
terms of time or money. But you simply cannot become an expert at what you do, regardless of your profession, without consid- erable investment in yourself. TE
