Tested soil temps today from just under surface to 4 inch depth. Temps in Full sun right under surface right at 40. Temps rose only slightly to 41 @ 4inches. Therefore, shaded soil temps still in 30’s,so all touch up seeding done in early 2014 still just sitting there doing nothing! Germination will not come for probably another 14 days minimum. However, we can delay preemergent at least until April 10th this year if you are waiting on new seed to germinate. It will happen!
