Fertilizer Injectors

A fertilizer injector is the most efficient way to feed plants. Utilizing your drip irrigation system, it delivers nutrients in liquid form directly to the roots of plants and is a fast and accurate way to feed an entire garden, landscape, orchard, nursery or greenhouse.

Add-It and Fertilizer Caddy, available in a variety of sizes to fit your fertigation needs, are simple to install and manage. Taking the guesswork out of operating a fertilizer injector, they eliminate the problem of figuring correct dosage rates and adjusting the flow, because they are pre-set to deliver a uniform 200:1 ratio (water to fertilizer).

Add-It Injectors are an appropriate choice for patio, deck or container plants of for small to medium size gardens.
