Been seeing little black flies like you see around the soil in most house plants. I’ve heard you guys talk about using dawn dish soap and water. What is the ratio? Per gallon. I googled and got a tablespoon. That was way too much. My plants look horrible a couple days after application. It’s the only thing that has changed in the grow. I hope they come back. Looks like the leaves have a black outline all along the leaves and little black spotting. First time I did companion planting. Don’t think I’ll do that again. I’m going to try mulch. Cedar chips maybe same as I use for my snakes terrarium. Any other tips for those little black flies would be appreciated. Thanks.
