Hello, I need to make a neem oil spray and was wondering if anyone had any good recipes for a 16 ounce spray bottle. I’ve been mixing neem oil with some liquid Castile soap and water. But I’m curious to hear what other people are using for their ratios. thanks much Katrina
I use 1/2 tablespoon castille soap and 1/2 tablespoon neem oil with 16 ounces water. I typically mix it in a liter bottle, so I use a full tablespoon each of castille soap and neem oil. I’ve heard of recipes that use hydrogen peroxide / isopropyl alcohol too but I don’t have experience with them. The most important thing is to keep your plants away from sunlight or grow lights for the next day, because their leaves could burn. Your watermelon peperomia is gorgeous!
