-If you spray more than one pesticide, check the labels before mixing them for compatibility or else you might end up with an unhappier looking plant than you started with.
-Reserve a special sprayer for weed killers, if you use them, because they are hard to thoroughly clean from a sprayer. The smallest residue might kill your plant.
-Lastly, think twice before using any pesticide. Be aware that plants tolerate a certain amount of pest damage; you might also.
