We'll be making our second round of lawn applications over the next couple weeks. This is the first time we'll apply a herbicide to your lawn. Why now? Well, the window for weed control is when temperatures are between 50 and 80 degrees. If it’s too cold outside, the herbicide won’t be effective. If it’s too hot, it can burn your grass. Once the ground temperature reaches 50 degrees and above, it’s time to start your spring pre-emergent weed control. The ground temperature will reach 50 degrees after we’ve had about a week of consistent 50-60 degree weather. If you’re still seeing annual winter weeds, such as springwood and henbit, rest assured, these will soon die off once the temperatures warm up.
