This spring when my perennials started to come up, I raked most of my mulch over to the edges of my garden. Now that the days will start heating up, I began raking it between my plants today. On one side of my border, as soon as I started raking, I saw a bright white substance- sticky, fungus-smelling, and almost thread-like; throughout one entire side of my garden. It has a strong odor- not necessarily disgusting, although I find it so- but very fungus-y. The mulch was piled about 4 inches, maybe a bit more in some places, but the white substance was present throughout- down to the ground. Do I need to remove all of the affected mulch or can it be treated in some way? I don't want to spread any sort of problem around my perennial garden as it is quite large. I first noticed this white substance last summer when I was transplanting a trumpetvine. It was present in the soil surrounding it- I could see there were pieces of cedar and other organic materials breaking down in the soil surrounding the plant and thought that it may just be nature's way of decomposing the wood. It is in the same area as the plant I transplanted (where it was originally anyway). Now I'm wondering if by transplanting the vine, I disturbed something and caused it to grow prolifically. It is rather unsightly. Thanks in advance for your help with this matter as well as my other recent issues. I appreciate your wisdom!
