I use sweet pdz granules on my roost boards. i was wondering can I take this straight off the boards ( manure mixed sweet pdz) and added it to flower beds in the fall on top of mulch after everything goes dormant? It is mostly hostas and ornamental shrubs. I’m in zone 4 northern ny my plants are usually dormant from October to March with lots of snow in the winter. Is this enough composting time / Is there still a risk of burning my plants?
