Someone please settle a discussion with a neighbor . I've used pre-emergents for years. And yes, I am well aware you have to water it in after applying.
But, I was having a discussion with a neighbor, who has their lawn taken care of by a lawn company. Apparently, they are convinced that regular watering is essential to keeping pre-emergent activated (this is what they have been told by the lawn company). That even in winter months, if you go more than a week without water, it will render the pre-emergent ineffective. I have never heard this before in my life. I have no idea what said company is using, but is that true for some products? I just can't image that being true and never having heard it before.
Anyway, I was just curious. I know there are some that are in the turf management profession that frequent here.
