Buying Guide
FAQs
What NPK ratio is best for my garden, and how do the listed products differ?
Most fish emulsion fertilizers have a low‑phosphorus ratio, typically 2‑3‑1 or 5‑1‑1, which is ideal for leafy growth and root development. The Alaska Fish Fertilizer (5‑1‑1) and Fertilome (5‑1‑1) focus on balanced nitrogen, while the 1‑gallon organic fish emulsion offers a 2‑3‑1 ratio for lighter, more frequent feeding. Choose 5‑1‑1 for vigorous foliage and 2‑3‑1 if you prefer a gentler, steady nutrient supply.
How important is odor when selecting a fish emulsion, and which options are less smelly?
Fish emulsion naturally has a fishy scent, but some products are deodorized or formulated to reduce the smell. Alaska’s 5‑1‑1 concentrate is deodorized with natural wintergreen, and the 12‑2‑2 powder from Fish Emulsion Fertilizer 12‑2‑2 reduces odor by being a dry form. If odor is a concern for indoor use, the powder or deodorized concentrate are better choices.
Should I buy a liquid concentrate or a powdered form, and what are the pros and cons?
Liquid concentrates like the 1‑gallon organic fish emulsion are easy to mix and apply quickly, making them great for regular foliar sprays and soil drenches. Powdered options such as the 12‑2‑2 powder provide higher concentration, lower shipping weight, and minimal odor, but require dissolving in water before use. Your decision should depend on storage space, application frequency, and sensitivity to smell.
Which product gives the best value for large garden beds?
For extensive plots, the 1‑gallon Alaska Fish Emulsion (5‑1‑1) and the 12‑2‑2 powder (3.3 lb) offer the most cost‑per‑application efficiency. The powder can cover up to 100 gallons per pound, reducing the number of containers you need to store. If you prefer a ready‑to‑use liquid, the 1‑gallon concentrate provides a high volume at a competitive price.
Are there any certifications or organic listings I should look for?
Organic certification helps ensure the product meets strict standards; Alaska Fish Fertilizer is OMRI listed, confirming its suitability for organic gardening. Central Garden Brands and Fertilome also label their fish emulsions as 100 % organic, though they don’t carry a specific OMRI seal. If certification is critical for your garden, prioritize OMRI‑listed options.
Can I use fish emulsion on both indoor and outdoor plants without causing burn?
Yes, most fish emulsions are low‑strength and designed to be gentle, reducing the risk of leaf burn when diluted correctly. Products like Central Garden Brands 1‑quart and the Alaska 5‑1‑1 concentrate specifically note “will not burn” and are safe for indoor foliage. Always follow the recommended mixing ratios to avoid over‑application.
How do I decide between a liquid fertilizer and a hydrolysate blend like FoxFarm’s Wholly Mackerel?
Liquid fish emulsions provide quick nutrient uptake and are ideal for regular feeding schedules, while hydrolysate blends combine fish protein with kelp and molasses for added micronutrients and microbial support. FoxFarm’s Wholly Mackerel emphasizes root strength and includes kelp for extra growth benefits, making it a good choice for seedlings and transplant stages. Choose a simple emulsion for general feeding, or a hydrolysate blend if you want a broader spectrum of organic inputs.
