i bought some neem oil for my ant infestation on my zygopetulum orchid. when i spray it on the plant, do i shake out all the bark and spray it on the roots? then replant it with new bark in a new pot. for the other plants that were next to it do i just spray it on top of the bark? the zygo had the next with eggs. help????
