|I have two different kinds of mushrooms growing in my roses. I have a container garden and used soil from a top nursery here in Boston. I am stunned by this and wondering if it is dangerous for my roses. They are on a deck -- no trees nearby.
|It is not dangerous to your roses. They are a natural part of the decay process and help break down the organic matter in the soil. If you think they are just too ugly you can remove them with a trowel and throw them away, they may show up again, or not. Their appearance seems to depend on soil moisture, temperature, humidity and so on. In any case it is nothing to worry about.
