Newbie here and I'm wondering if I made a mistake that needs to be fixed. I just got some aged horse manure from a friend. Applied it around my roses about 1 inch thick. Now I'm concerned it isn't aged enough and it's going to hurt them. How aged is well aged manure? It was ground pretty fine by the horses hooves so small particles. Didn't have a strong smell but still did smell a bit, and it still had some clumps that were identifiable. Should I go back and remove it from around the roses and compost it longer? Or is what I did ok?
