This sprayer works so well. My only tip is if you fill it to the 2 1/4 if it makes it more difficult to get the pressure. I typically will do a gallon at a time. I use Rosemary oil so you have to be careful and clean it otherwise the top is hard to get off. This saved both my hand and my pine tree that was infested with spiders. If have a pine that is turning brown it can be related to overwatering and then an infestation of spiders which sucked the chlorophyll out of the plant.
