1 Gallon Organic Fish Emulsion Fertilizer for Plants
The Grow Co offers a liquid fish emulsion with a natural 2-3-1 NPK ratio, designed for light, frequent applications. It emphasizes sustainability by using fish parts that would otherwise go to waste and refining ingredients cold to retain nutrients. Best for organic lawn care or light feeding schedules where steady growth is desired. A key limitation is that it’s formulated for general plant use; lawns needing higher nitrogen bursts may require follow-up applications.
Fish Emulsion Fertilizer – 8 oz
TPS NUTRIENTS’ liquid fish emulsion supports root strength and lush foliage for both indoor and outdoor gardens. It provides essential nutrients for healthier crops and is suitable for vegetables and general garden plants. Best for: gardeners seeking a quick-acting, nutrient-dense option for moderate feeding. Limitation: smaller bottle size means more frequent applications for larger lawns.
GS Plant Foods Liquid Fish Fertilizer
GS Plant Foods’ liquid fish fertilizer is OMRI listed and features a balanced 2-3-1 ratio. It’s suitable for a wide range of plants—from vegetables to ornamentals—and works well for lawns that follow organic growing standards. Best for: organic home lawns and mixed plantings. Caution: verify application rates to avoid over-fertilizing sensitive ornamentals near the lawn edges.
Fertilome (10611) Fish Emulsion Fertilizer 5-1-1
Ferti-Lome’s fish emulsion fertilizer is a 5-1-1 formula designed to promote deep green foliage and vigorous root systems. It’s applicable indoors and outdoors and can be diluted for plant watering or used through other methods. Best for: lawns and beds needing stronger nitrogen early in the season. Limitation: higher NPK means potential for rapid foliar burn if overapplied on sensitive turf edges.
Fish Hydrolysate Fertilizer – 16 fl oz
PLANTCO’s fish emulsion emphasizes hydrolyzed fish nutrients with amino acids and natural growth compounds. It is marketed for vegetables, flowers, and general lawn use, offering a nutrient-rich option in a convenient 16 oz bottle.

Buying Guide
What should I consider when choosing fish emulsion for my lawn?
- NPK balance: Decide whether you need a higher nitrogen feed (green growth) or a balanced feed for steady growth. Lawn care often benefits from 2-3-1 or similar ratios, plus consideration of micronutrients in hydrolysates.
- Organic certification: If you prefer organic lawn care, look for OMRI-listed products like the GS Plant Foods option. Such labeling aligns with organic gardening standards.
- Application method: Liquid emulsions can be used as soil drenches or foliar feeds. Consider your watering setup and whether you want quick-release nutrients or slow-release feeding over time.
- Target plants and space: For large lawns, consider larger-volume containers with scheduling that matches your mowing cycle. For container lawns or small patches, smaller bottles may be more practical.
- Odor and aesthetic considerations: Some fish emulsions have stronger odors than others. If odor is a concern, select products that emphasize milder profiles or use indoors/controlled spaces accordingly.
- Safety and maintenance: Avoid over-application, especially near roots of sensitive plants. Follow label directions and water after applying to prevent root burn.
Ways to Use
- Soil drench: Mix according to label directions and apply around the base of the lawn to nourish the root zone.
- Foliar feeding: When weather is calm, apply as a light spray to leaves to support nutrient uptake and photosynthesis.
- Tank mixes: For a broader nutrient profile, paired with other organic amendments, ensure compatibility and avoid overloading soil with nitrogen at once.
