 Well, you can make it yourself. The formula is on DirtDoctor.com. It's a mixture of compost, tea, vinegar, molasses, seaweed, and you can put orange oil in it if there are some chinch bugs in there. But the formula is always on my website and in my books and available. You can buy the commercial products, too, if you don't want to make your home brews. But it's available either way. Where do you find it if I do want to buy it?
