I didn't have any mulch yet since it hasn't really stopped raining on my days off for me to work in the yard.. I needed to get my rhizomes in the ground and did a 2" layer of poultry compost followed with 3"of gardening soil then the rhizomes with a 2"to 3" layer of gardening soil.. I had forgot to pick up some mulch and it started getting dark and started to rain so I hurried and raked some pine needles out of the front lawn from last year and put a inch layer on top of each one.. Is this ok? The wife called and said it's snowing.. Should I be worried that there getting to wet also. I only got the dirt moist yesterday after planting..
