Hi there! I’m writing a guide on "How to Keep Mulch from Washing Away on Slopes and Hillsides" and would appreciate your expert input. I am looking for a turfgrass specialist to weigh in on these technical challenges: 1. Beyond just steepness, what are some common mistakes homeowners make when prepping a slope that causes even the best shredded mulch to fail during the first heavy rain? 2. In your experience, do liquid mulch stabilizers actually provide a significant ROI for residential slopes, or are physical barriers like jute netting and benching always superior? 3. How does the underlying soil type (heavy clay vs. loose sand) change your recommendation for which interlocking mulch or sticky organic material to use on an incline? 4. For a slope that has already begun to show signs of creep (mulch sliding down), what are some tricks to stabilize the existing material without having to strip the slope and start over?
