Systems and methods are disclosed for delivering a substance into a plant. The systems and methods include a light energy that is applied to a first area on the plant to create a first indentation. The first indentation can be a minor incision or a rupture of a portion of the first area. Once the first indentation is created, a first dosage of the substance is applied to the first area in an amount effective to promote a biological response of the plant. It is contemplated that at least a portion of the substance is absorbed by the plant via the first indentation.
