I mulch with broken sticks or pine bows. Not deep, but just enough to discourage the birdies and the rodents. I want birds, as they are the only thing that eats the SLUGZOMBIES...also...make sure you are popping your peas in at least 1" deep. Any less, and they'll pop themselves out and signal to the birds that there's a nice snack here! But broken sticks work really well and also create a little micro climate/moisture trap
