Top five reasons it’s an epic crabgrass year
There are several reasons for crabgrass being especially troublesome this summer in Michigan.
I was recently asked by a lawn care operator to reply via email with 1,000 words or less of why it’s an epic crabgrass year – well, maybe he didn’t say epic, but you get the idea. I accepted this challenge heartily, but decided in the spirit of today’s world of texting and twittering to do it in less than 100 words.
- Record heat and stress in 2012 resulted in bumper crabgrass crop, plenty of seed, and thinned turf for more opportunities for crabgrass to invade this year.
- Cold, long, spring-delayed crabgrass germination, may have escaped early spring preemergence applications.
- Soil moisture increases soil biological activity, in turn, increasing herbicide degradation.
- Plentiful precipitation in June when young crabgrass was geminating helped with root development.
- High temperatures in July were perfectly timed for crabgrass to really start competing.
