Organic Neem Cake Fertilizer 5 lb - Natural Plant Food for Vegetables, Flowers & Lawns - Ideal for Organic Gardening, Pest Control & Soil Enrichment

I probagate (take slips and make new plants.) at the end of summer. I have 85 plants. I mixed up 2 gallons and used it as the water medium in the soil. I put water in gallon container and 3 1/2 heaping tsp per gallon of water. Let sit 2 hours. Every plant was done this way. It has been 5 weeks and I have not seen a single gnat. Now, you can't mix up more than you need and save for later, because it will ferment and smell bad. As for some of the people's reviews, I did not have a bad smell in the plants. Maybe they added too much to the top of the plants. But no overwhelming bad smell at all. Thankful for this. product.
