Up here in MA it seems the temps are changing, warranting a later application of crabgrass pre-emergent. I have noticed even using good products like dimension, they will sometimes break down come late July or August. I have seen that Lesco has a 0-0-7 Dimension, can that be applied in the late June/early July time frame to further extend the crabgrass pre-emergent coverage. To be honest, I just recently saw this product, and am not really sure what time of year it can be applied. Since it seems to be mostly Dithiopyr and Potassium, I would think it would not burn the lawn in the hot summer heat, is this true?
