Insecticides

Neem oil comes from a tree. It works best if the plants have been hit
previously with something heavier (systemic insecticides/fungicides) and it
seems to further deter pests temporarily while giving a glossy sheen to the
plants Good if you are taking plants somewhere to show, sell or display as
the plants won't reek of chemicals.
