It may be a good reminder that what we experience in a given situation, is not a valid point to 'generalize' into all situations. The ability for a professional lawncare person to understand basic principles and apply them to individual situations, is Paramount to anyone in the business. We can read an article and believe that it is saying something is good or bad, but we can't understand, "Why", it is good or bad, in this circumstance, then ask the question : "Will it", be good or bad in a different : time of year, texture of soil, available moisture, climate, cultural practices, amounts of apps, etc., etc. It's as if an idea has been understood and it becomes the ONLY way to understand it. That may be what is lacking in the industry. Is it wise to dethatch ALL lawns in Spring?, pre-m ALL lawns in Spring(twice), fertilize ALL lawns Early Spring?, irrigate ALL lawns 4 days a week for 45 minutes?, bag clippings on ALL lawns(every time)? Can anyone name one thing that is best if it is always done on every lawn? What is the One Thing that is the SAME for every lawn, that makes it the best way to go?
