Tricia pours liquid fertilizer in to the Add-It pint-size Fertilizer Injector

A labor-saving device that fertilizes plants automatically.

It sounds like a gardener’s dream come true, doesn’t it?

Say hello to fertilizer injectors and mixers—they will do your fertigation for you.

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 new video.

Which fertilizers?  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

The most durable of our simple devices is our Brass Siphon Mixer. One end of this ingenious brass 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 50’ or less in length.

For gardeners who have low water pressure and use sprinkler systems or drip irrigation

The Add-It Proportioning Fertilizer Injectors and the EZ-Flo System are the next step up. Each of them accommodates low water pressure and either drip irrigation or sprinkler systems.

Tricia uses this pint-size Add-It Fertilizer Injector in the videos. Easy to operate, the Add-It injects fertilizer at a 1:200 ratio (2 tablespoons per gallon). A minimum pressure of 10 PSI is required. A backflow device, like our Vacuum Breaker, must be installed before the injector, and a filter is recommended when injecting fertilizers into drip irrigation. Add-It does not need a by-pass because running water through the empty unit will not harm it.

You can attach the EZ-FLO Automatic Fertilization System to a hose, or install it as part of a sprinkler system or drip system. The EZ-FLO is an economical and flexible system for automatic fertilizing. Unlike similar systems, you can see the amount of fertilizer solution as it is used. Made of commercial grade components, the EZ-FLO is appropriate for residential or commercial growers and landscapers.

For serious home and commercial growers

When you want to be able to easily calibrate the amount of fertilizer that goes on your plants, the best choices are the professional-quality mixer-proportioners.

The 2-gallon Young Mixer-Proportioner is simple, virtually indestructible, and very accurate. It’s a good choice for home or market gardeners who do a lot of injecting or spraying (soluble fertilizers, foliar feeds, soil inoculants or pest controls). The tank comes lined with a replaceable bladder-type bag that lasts several years. To operate, just fill the tank with concentrate, dial in the desired ratio (select from 1:30 to 1:200), turn on the water and that’s it! Minimum water flow rate is 2 GPM. Look through the clear plastic outlet to see if the concentrate is finished.

A popular, long-lasting choice is the Venturi-type Mazzei Injector. The Mazzei connects at each end to the irrigation line, and a downward-facing arm is the conduit for the liquid fertilizer. High water pressure in the irrigation line creates a vacuum that pulls the liquid fertilizer in to the water stream. Check our different Mazzei injectors to coordinate with your gallons per minute. These low-cost, accurate injectors are capable of higher flow rates than the other injectors we carry. They require a bit more installation expertise, but the cost savings can be worth it.
