Fish emulsion is organic fertilizer used on edible vegetables and ornamental plants to deliver nitrogen, phosphorous and potassium plus micro-nutrients to the soil and plant roots. They are sold in concentrated liquid form and are mixed with water before application. The emulsion is made from blended-up fish tissues and bones that have been treated with heat and acid to prevent unhealthy bacteria from developing.
Commonly found with a guaranteed analysis ratio of 5-2-2, fish emulsion offers benefits that persist in the soil for several months at a stretch.
Mix 6 tablespoons of a liquid fish emulsion product for every gallon of irrigation water, multiplying the recipe as needed to adequately water your vegetable patch. Mix large batches in a bucket or watering can just as you need it.
Pour the treated water around the base of the plants and over the foliage if desired to water and feed the plants. Wet the soil to the degree of moisture that particular vegetable plant prefers.
Repeat applications of fish emulsion with irrigation every one to four months in keeping with the dosing and frequency recommendations on the product label.
