How to Foliar Feed your Plants

Foliar feeding is a great way to get your plant some additional nutrients and improve growth. In cases of root zone issues or lockout, foliar feeding is a quick way to get nutrients into your plant that it can't get through the root system. Contrary to what some nutrient companies tell you, just about any liquid nutrient or tea brew can be foliar fed. The trick is mixing the foliar feed and applying it correctly.

 

Mixing your Foliar Feed

Your foliar spray will contain three items : nutrients, a surfactant/wetting agent, and water. Multiple nutrient products can be used but this is a basic tutorial and when starting out we recommend starting with one to keep it simple. Over time you can improve upon your recipe. For your first feeding take the lowest recommended feeding dose and cut it in half, it is better to underfeed than overfeed and burn your plants. Measure out that reduced dosage for the amount of water you have and mix. To thoroughly coat the leaves and maximize uptake wetting agents like Earth Juice Assist are used. If you're in a bind and don't have or can't afford a wetting agent, a couple drops of plain dish soap can be used. Be sure to get something that is plain - no anti-bacterial properties, no dies, scents,etc. Finish mixing and you've got your foliar spray ready to use. 

 

When and How to use your Foliar Spray

Foliar sprays are best applied in early morning before the sun is blasting down onto your plants. Evening could work as well but you risk inviting mold or mildew if there isn't enough time for the spray to dry, just like why you shouldn't water your grass in the evening. Apply a light misting to both sides of the leaves to thoroughly penetrate. Use a spray bottle that has a finer mist type setting or has a nozzle adjustment rather than a spray bottle that only does stream and spray (like many household cleaner bottles). If you haven't used your foliar spray before we recommend treating a test area the first feeding to make sure it doesn't cause nutrient burn or cause the sun to cook the leaves. Wait a couple of days to make sure, then apply to the rest of your plant. Congrats, you've now just created and applied your first foliar feeding! Feels good, huh?
