The present invention provides a liquid sprayer for plants having a wand with a gas supply tube for providing a flow of a pressurized gas and a liquid supply tube for providing a liquid to be sprayed. A discharge end of the gas supply tube and a discharge end of the liquid supply tube may be arranged so that the pressurized gas through the gas supply tube flows across the discharge end of the liquid supply tube thereby drawing or siphoning the liquid through the liquid supply tube into the flow of the pressurized gas for dispersal. The liquid and pressurized gas combine to create a fine mist or fog that provides a gentler and more even application over the plant surface.
