I'm a new gardener and after reading many books, decided to make raised/lasagna/kill mulch beds. I have 5 4x8 beds(a huge upgrade from a 4x4!!).In November I added about 4-6 in of a mix of horse manure and leaves. As soon as the snow melted I laid down a layer of cardboard. I talked to an organic gardener in Orem that suggested I get mushroom compost for the top layer of my bed, he recommended going to Cook's. I went to Cook's Greenhouse and was advised a mixture of nutrimulch and mushroom compost would be best. I laid down 4-6 in of the mixture and planted peas, carrots, lettuce, beets, bunching onions, swiss chard, chives, and radishes on March 1. Yes, I was overzealous. Yes, I was very excited for the growing season! Well, the weather turned pretty ugly but my lettuce started coming up, and the peas finally started coming up about 3.5 weeks later. I've been watering pretty much everyday. My mom was worried about the compost burning my plants, I told her it should be fine, I had gotten good advice. I transplanted my broccoli and kale 4/1. I noticed on Monday (4/22) that the top leaves of my peas are turning yellow. I called the USU ext and they said pull back on watering. I went to Cook's again and they said mushroom compost and nutrimulch need to be mixed with soil. Uhhh, WHAT? They said sorry someone had given me bad advice! So, I'm pretty much freaking out over here since I have plants that need to be transplanted soon. The lettuce, kale, and broccoli seem to be doing just fine. My last years strawberries are turning brown, but are flowering. I'm guessing I'm going to have to get top soil and just mix everything together. Can anyone give me some good advice please?!
