This may sound stupid, but I have a question. I have a large mulch job set for fri and sat and we have a freeze warning for the next couple nights, lows in the low to mid 20's. I wandered if I should hold off untill next week, for two reasons. 1 Somewhere I heard you should not mulch if the ground is frozen, 2. we are planting perennials and I don't want to put them in just yet, due to the cold temps. I don't think that it will get cold enough to really freeze the ground, but I would like to hear what you guys think. This is a new customer, and I want to keep her happy, but I don't want to screw anything up.
