Foliar Feeding and Pest Control for Living Walls

Florafelt Pockets foliar feeding by David of Living Green Design for a San Francisco downtown rooftop.

Nutrients are absorbed by the leaves

Foliar feeding is an easy and effective way to provide nutrients to your plants. Food is effectively absorbed through the leaves.

Add pest control to the mix

At the same time you can deliver protection against pests by adding horticulture oils and biocides to the mix.

For outdoors use a hose end sprayer

Use a hose end sprayer to deliver a concentrated mix of water soluble fertilizer and pest control in one application.

Adjust the mix

Use the dial on the sprayer to adjust the amount of fertilizer being injected into the water spray.

In the hose sprayer container:

  • Add the water soluble plant food. Follow the plant food directions to create a concentrated mix that is dark in color.
  • Add about 2 TBSP each of the insecticide additives.
  • Shake the sprayer as you go to keep the horticultural oil in the mix.

Pro Tip: Spray a white wall nearby and adjust the sprayer so the solution is a very faint color. This is all you’ll need to safely fertilize your plants and prevent leaf burning.
