How to Choose the Right Foliar Spray for Your Garden

What is a Foliar Spray?

A foliar spray is a liquid that is sprayed on the leaves of plants. It can be used to provide nutrients and control pests and fungus. Foliar sprays can also be used to add water or act as a pesticide. Foliar sprays are usually applied with a trigger or pump sprayer.

Foliar sprays are not an alternative to building up a healthy root system. Vegetables need nutrients such as nitrogen, phosphorous, potassium and nitrogen to survive and be healthy. These major nutrients wouldn’t be able to absorb solely through being fed their leaves.

Having said that, it is a great way to supply micro-nutrients such as iron and zinc. Your plants may not be using these nutrients in large quantities, but they may not be present in the root zone and are considered important to keep them healthy. If your plants are under stress from drought, pest-infestation or disease, it’s worth spraying them. A debilitated plant can recuperate noticeably after being sprayed with Optic Foliar Overgrow.
