Organic Pure Cold Pressed Neem Seed Oil

Had a serious rose infestation on 50 Knockout rose bushes. They were loaded with Aphids, rose slugs, and numerous other rose devouring pests which were destroying all my plants in the landscaping..Did all I could; sprays , hand washing you name it and what a nightmare as I watched all the roses drying up and drying because of all the attempts to save them..Researched and decided to do a soil soak with Neem Oil and Castile soap mix..mixed up several gallons and went around all the Knockouts and other shrubs with around 2 cups on each shrub of the mix..I cannot believe after a few weeks and 3 dousings there is NOT one stinking Aphid or Rose slug on any of the Knockouts or anything else!!...It stinks and the smell will stay with you but when you see a bugless garden it becomes a welcome fragrance as it saved my landscaping and I now give them a dose about every 10 days and water frequently..Still nothing is eating them and if they do they are dead dried up stuck to a solitary leave or 2...This will harden up in the bottle so I put the container in hot water in a bucket and it pours nicely after..I also mix this with a gallon of "hot" water and a tablespoon of Castile with 2 tablespoons of Neem and shake to break it down. It solidifies and It doesn't work in cold or warm water just hot but everyone tells you to use warm and I don't understand why..This is a good product for me and it has been working good at a good price..UPDATE, it has now been about 2 months since I have been doing the soil soak. I have been increasing the Neem oil to about twice the amount per and all the roses are going crazy with dozens of new buds on every plant and still not one stinking rose eating bug..This has been totally organic and it has been acting like a fertilizer. The bees still are roaming around everything without any regards and have been increasing pollinating everything..I had pests which were terrorizing the "rose of Sharon, lavender, hydrangeas and others chewing the hell out of the leaves making them look like Swiss cheese, but all stopped since they have been getting the Neem oil soil soak also...Really a good remedy..Forget about spraying the plants do the soak....
