mushroom compost

[Anton Jopko]

Dear Readers, This spring we planted several roses and they turned out beautifully with many blooms. Now we have to worry about the winter. Is it safe to use mushroom compost to winter protect roses here in zone 5? a person told me that the compost is high in salt?? Thanks for listening anton

I wouldn't use mushroom compost as an overwintering insulator for roses. My personal preference is pine needles, heaped to above the graft point.
