Cinnamon oil sounds interesting. A little bird told me it works however I haven't quite grasped when one would use it. Does one use it for both insect and arachnid infestations? Is cinnamon oil diluted before used and if so with what? Exactly how does one apply it? Does it dammage new growth and if so, to what extent? Can this process be applied to other CPs or is it ony safe to use on Pings. Why does it work?
What does everyone think of horticultural oils?
