Most gardeners struggle with the guesswork of measuring powders, but this LiquaFeed system turns fertilization into a precise, effortless routine. Instead of messy granules that sit on the soil surface, this kit provides a streamlined liquid delivery method that gets nutrients exactly where they need to go. The starter kit is incredibly comprehensive, giving you a dedicated garden feeder, a dosing spoon for accuracy, and an initial 16 oz. bottle of all-purpose liquid plant food. What sets this specific bundle apart is the inclusion of a secondary refill pack, ensuring you won't run dry mid-season. It transforms a chore into a simple, controlled process that makes maintaining a vibrant patio or lawn feel much more professional.

Jobe's organic fertilizer spikes are the gold standard for gardeners who want professional results without the messy guesswork of traditional liquid feeding.

Because it is OMRI Listed for organic use, you can garden with peace of mind knowing you are using all-natural ingredients.

Because it is derived from organic fish and grain, it doesn't just feed the plant. It activates the indigenous micro-flora already living in your soil.
