Pre-emergent question
Posted: February 7th, 2020, 6:25 pm
I know that pre-emergent should be put down in the spring when the soil temperature reaches 55. I live in the Dallas - Fort Worth metroplex and the local gardening guru says to put it down between March 5 - 15. I've been following that date for a long time and have been less than satisfied with the results. The problem with our area is that it will often get really warm in February for a few days and then cool back off and become more winterlike. It causes all kinds of confusion with the spring bulbs, etc. I believe it also causes some weeds and unwanted grasses to germinate early. I'm thinking that I may treat the lawn twice this spring. The first treatment around Feb 15 and then the second one in the traditional March period. My question, am I going to harm anything (other than my wallet) by doubling the treatment so close together? I feel that with the two treatments, I'll have a better chance for good results. I'd appreciate any advice or discussion on this.
