Mostly great success with Dimension, though it really only performs at the highest rate. I find that it is easy to find a cheap granular Dimension, not so much the barricade, so I tend to use it more. I use Prodiamine in spray form as a result where it is cheaper, and only when I have to have long term from one spray, but it’s pruning capacity in early spring has given me some issues even on Bermuda.

Pre or Post, each has a negtivive effect on turf, it may not be a visual difference but each has made an impact. A home owner who has the time, and time being the key word should be able to manage their lawn without the use of these products or very limited. Have you ever noticed the old man that has the lawn on the corner of the street, how nice his lawn is? He mows and mows, maybe to get away from his wife, maybe time to solve lifes problems, but hes mowing his warm season grass, on a 3-5 day schedule. We find that high frequency mowing is one of the most over looked culture pratices here in states. Having a golf couse type lawn requires a golf course type effort, and Effort being the key word. My experience is I can manage my own lawn without the use of pre or post emergence, this requires a special technique called Bendaknees. Bendaknees has long been forgotten, as it requires time and effort. So when we can't master this "Time or Effort" We have a eazy solution, Pre and post emergence herbicides. We manage about 350 residential sites, about 75 acres, and it is impossible to manage without the use of all the above. But you are on to something about not using Pre emergence, if you have the time, try Bendaknees, if time is of essence try spot spraying your crabgrass. The big box stores do have some products that work, but it seems that most crabgrass products all seem to stress the temperatures in the 80s or below. As a professoinal I find most of Matts videos are right on the spot, Further more I would say even as a professional Ive learned more from Matt than any Turf school or professer.

I no longer use pre-emergents on my personal turf due to the damage developed over a 30 year period. Information on root pruning in turf was never provided to me. I certainly suspected some type of toxicity as the grass declined over time. My lawn has recovered, but it did take 2-3 years. I think short term use of pre-emergent products are great when there is high weed volume. I do need to use one of these products over cobblestone. Will prodiamine stain concrete and stone?

Señor Matt, I have a question. 🙋🏽♂️ One of the other KZfaq guys coincidentally mentioned something I’ve been thinking about recently. He mentioned that after a few years of applying pre-em to his lawn, he got to a point where he felt his lawn was strong enough. So he’s gone a couple of years without applying any pre-em at all and that he only treats with post-em. Can a lawn get that healthy? Would maybe a reduction of the label rate be better? Like him, I have had the good fortune of not having had any weed issues over the last 3 years. I hand-pull the occasional poa annua or dandelion that comes up.
