Hi - I made a bit too much of holistic spray based on Michael Philips' recipe in The Holistic Orchard. It contains neem oil, karanja oil, activated EM-1, liquid kelp, and fish hydrosylate. I have 2 gallons leftover and am not sure how to use it up, as I already sprayed all the
trees on my property. Thoughts? Does it store well in the fridge? (If yes, I could save it for the fall or next spring.) My impression is that, of the ingredients, neem oil and karanja oil have antimicrobial and antifungal properties, so I'm hesitant to just spray / dump the rest of it in my vegetable garden.
Thank you in advance,
Boris
