Hi,

I posted this on the rose forum, but no one answered. Figured I'd give it one more shot here.. I went to the nursery and asked for horticultural oil for mixing up Cornell formula. The product they gave me is called "Year Round Spray Oil" and includes the following ingredients: 98.8% paraffinic oil, 1.2% emulsifier. Is this product appropriate to use in this application? (Is it even organic, for that matter?)

Thanks for any help,

Michele
