Hi all,

I am at Chicago north suburb area. The temperature is acting weird recently.

The GDD tracker seems to indicates that I shall be put down pre-M in the next week.

However, the temperature is foretasted to be below 50 in the next week and the 2 inch soil temperature only has two days hits 55 f in the last 2 weeks.

In this case, shall I wait till the soil temperature recover to 55f, then apply the pre-M?

I am using Hi-Yield Weed and Grass Stopper with Dimension.
