I just recently noticed in my flower bed when I turned my mulch, it was moldy. I had planted some Calla Lilies in the middle of spring. One of them had bumps all under the one side. I figured the mold was the cause. I am wanting to plant some tulips and daffodils for next spring, but I was going to remove all the mulch first since I don't want those bulbs to get sick as well. My question is, can I put down potting soil after removing the mulch, and then next spring put in new mulch? I live on a military base, and it is lease agreed that the flower beds in front are to have mulch. Would my idea work, or should I just put down mulch?
