How can I use copper sulfate to tackle fungus on my balcony plants?
I'm noticing some funky fungus growing on my balcony plants this fall, and it's not looking good! I live in NYC, and with my small space, I’ve got quite a few containers all packed together. I've been trying to keep the airflow up, but it seems like the humidity and rain are bringing out the fungi in full force. I’ve read a bit about copper sulfate being a potential solution, but I’m not sure how to use it safely with the limited space and the risk to other plants. Can anyone help me figure out how to apply it without harming my other veggies? Would appreciate any advice or tips you've got!
