FAQs
What NPK ratio should I look for in a fish emulsion when feeding transplants?
Transplants benefit from a balanced, slightly higher nitrogen ratio to encourage rapid leaf growth; a 5-1-1 or 5-1-2 ratio is ideal for this stage. Products like Alaska Fish Emulsion (5-1-1) and Fertilome (5-1-1) match this profile. If you prefer a gentler feed, a 2-3-1 ratio such as the Organic Fish Emulsion can also work well when applied more frequently.
How important is odor when choosing a fish emulsion for indoor or greenhouse use?
Odor can be a concern in enclosed spaces; deodorized formulas like Alaska Fish Emulsion use natural wintergreen to mask the smell, while powder options like the 12-2-2 Fish Emulsion Powder are virtually odor‑free. Traditional liquid emulsions, such as the 1‑gallon Organic Fish Emulsion, have a strong fishy scent that indicates authenticity but may be less pleasant indoors. Choose based on your ventilation and tolerance for scent.
Which product gives the best value per volume for transplant feeding?
When comparing cost‑per‑gallon, the 5‑gallon Alaska Fish Emulsion and the 1‑gallon Organic Fish Emulsion are both economical, but the Alaska version includes a deodorizing additive and a burn‑safe claim, adding extra value. The 12‑2‑2 powder delivers up to 100 gallons per pound, making it the most cost‑effective for large plots, though you’ll need to mix it into a liquid yourself.
Should I use a liquid fish emulsion or a powdered form for my seedlings and transplants?
Liquids like Alaska Fish Emulsion or FoxFarm Wholly Mackerel are ready‑to‑mix and provide quick nutrient uptake, which is helpful for fast‑growing transplants. Powders such as the 12‑2‑2 Fish Emulsion Powder have a longer shelf life, lower odor, and can be diluted to very large volumes, making them suitable for growers who need to treat many plants with consistent strength. Your choice depends on convenience versus storage and odor considerations.
What certifications or ingredient lists indicate a truly organic fish emulsion?
Look for OMRI certification, as seen on Safergro Aqua Power, which guarantees the product meets organic standards. Additionally, products that state they use 100 % cold‑pressed, sustainably sourced fish (like the Organic Fish Emulsion) avoid synthetic additives. Checking for listed amino acids, vitamins, and minerals also signals a high‑quality organic formulation.
How do I avoid burning my plants when using a concentrated fish emulsion?
Always dilute according to the manufacturer’s instructions; most 5‑1‑1 concentrates recommend 1–2 tablespoons per gallon for foliage and up to 4 tablespoons per gallon for trees. Products that advertise “will not burn,” such as Alaska Fish Emulsion, are formulated with lower salt content, but proper dilution is still essential. Start with a weaker solution and increase gradually as plants show tolerance.
Can I use the same fish emulsion for both soil drench and foliar spray?
Many fish emulsions, including the Organic Fish Emulsion and FoxFarm Wholly Mackerel, are safe for both applications; they provide nutrients through roots and leaves. Foliar sprays should be applied at a lower concentration (often half the soil‑drench rate) to prevent leaf burn. Follow each product’s label for the recommended mixing ratios for each method.
What extra ingredients should I consider for transplant vigor?
Formulations that include kelp, molasses, or additional amino acids—like FoxFarm Wholly Mackerel and Safergro Aqua Power—supply micronutrients and feed beneficial soil microbes, boosting root development. These additives can improve stress resistance and overall plant health beyond the basic NPK values. Pairing a fish emulsion with a root‑stimulating additive can give transplants a stronger start.
