Is fish oil a good fertilizer?
Also asked, is fish oil good for your garden?
Fish oil, a byproduct from fish processing, provides benefits similar to those of plant oils when used in the garden. The oil can help your plants remain healthy whether you need to combat pests or add nutrients to the soil.
Keeping this in view, can oil be used as fertilizer?
ANSWER: No. Oil is not used in the production of fertilizer. The macronutrients required by plants are N (Nitrogen), K (Potassium) and P (Phosphorus). There are no plant nutrients in oil.
Use a weak solution of 1 teaspoon per gallon when transplanting seedlings or bedding plants into the garden. Apply diluted fish emulsion to outdoor plants, including container plants, every three to four weeks throughout the growing season -- generally from spring to late summer or early autumn.
