Know before you buy
Yes, it is suitable for houseplants, vegetables, flowers, and shrubs. Because it is a liquid concentrate, ensure you dilute it according to the instructions to avoid over-fertilizing sensitive indoor plants.
Enzymatic digestion breaks down the marine fish into peptides, which are smaller molecules that plants can absorb much faster than raw organic matter. This makes the nitrogen and phosphorous immediately available for your plants to use.
No, this product is specifically formulated as a root drench. Applying it directly to the soil ensures the nutrients reach the root zone and effectively support the beneficial microbes in your soil biology.
Absolutely. Its gentle, readily available nutrient profile makes it an excellent choice for seedlings and new transplants, helping them establish strong root systems and vigorous early growth.
As it is derived from marine fish, it does have a distinct, natural fishy scent. While the smell typically dissipates quickly after application into the soil, it is best used in well-ventilated areas or outdoors.
Frequency depends on your specific plant's needs and growth stage. It is best to follow the feeding schedule provided on the bottle, as this allows you to adjust the dosage based on whether you are supporting early development or ongoing maintenance.
