1. When green grass composts, it can get hot, like 130-150 degrees F. That would not be good on the plant.
2. Sometimes grass clippings can mesh together into a water resistant pad which will slowly decompose from below if kept moist, which fertilizes and mulches. Water from me or the rain can get under from the space around the PS, just don't overdo it and cause the corm to rot. I check for this and break up this meshing so water can get thru. Once you break it up it won't re mesh until you add new clippings.
He is using oak leaves, most likely live oak leaves which I tried to use but they become impermeable to water and rot very slowly, from the bottom up.
