Neem oil is an organic, non toxic oil extract from the neem tree. Mixed with water and a few drops of dish soap it is very useful in curbing the ?appetite? of the so-called ?Lily Beetle? for the foliage of lilies. You?ll still need to squish the critters regularly, but this spray helps slow them down. Sold as a ?leaf polisher?, it?ll keep your leaves shiny too! Each 125ml. bottle goes a long way. Makes about 25 litres of solution.
