Q.Mold In Soil

Zone 9B | Anonymous added on October 30, 2023 | Answered

I did this without thinking ahead. I bought a hugee bag of Miracle Gro and put it in a watertight container in the greenhouse. I opened it 2 weeks later and there was mold or mildew growing throughout the container. I took it out of the greenhouse right away and have no intention of using that soil in the greenhouse now, but can I use that soil outside in my potting containers? Thanks in advance

This really depends on the kind of mold that is growing. Some of those can be beneficial to soil, whereas some can do some real damage to plants and animals. To be safe, I would re-compost, or discard completely.
