What's fertigation?

Fertilizer + Irrigation = Fertigation. Whether you water by hand, use a sprinkler system, or a drip irrigation system, you can give fertilized water to your plants. Tricia walks you through the different devices for fertigation in our video.

Which fertilizers are best for fertigation?

In one of our videos Tricia explains how to choose and apply the best fertilizers for your plants. Water-soluble or liquid fertilizers are diluted and sprayed on leaves (foliar feeding) or watered into the soil. Here's how to choose the best fertilizer mixer or injector for the irrigation you use. For gardeners who have low water pressure and water by hand grow more siphon mixer injectorOur simplest device is our Grow More Siphon Mixer Injector. One end of this ingenious siphon mixer screws onto your hose bib, the other attaches to your garden hose.

The mixer has a small siphon tube that drops down into a bucket of liquid fertilizer and takes the concentrate up into the hose line at a 1:16 ratio as you water. A backflow preventer is integrated into the mixer. Use this mixer with hoses 200' or less in length. Must be used with an atmospheric Vacuum Breaker If your house was built within the last 40 years, it will likely have a Vacuum Breaker in place.

For gardeners who have low water pressure and use sprinkler systems or drip irrigation The Chapin Hydrofeed Injectors are the next step up. Each of them requires a pressure of about 40 psi.  A backflow device, like our Vacuum Breaker, must be installed before the injector, and a filter is recommended when injecting fertilizers into drip irrigation.
