Comparison: Best Alaska Morbloom Fish Fertilizer (Updated | Dec 1st)

The gallon size offers a lower price per ounce and is ideal for larger gardens or frequent applications, while the 32 oz pack is convenient for small spaces or trial use. Both share the same 0‑10‑10 nutrient ratio, but the larger container may require more storage space. Consider how often you plan to fertilize and the volume of plants you have when choosing.

Both are organic fish‑based fertilizers, but the Alaska product is OMRI listed, ensuring it meets organic certification standards, whereas Central Garden Brands emphasizes a broader vitamin profile. The Alaska fertilizer comes in a larger 115 oz container, offering more value for extensive use, while the Central Garden Brands version is a 1‑quart bottle suited for smaller applications. Choose based on certification needs and the scale of your gardening projects.

The deodorized version contains natural wintergreen scent, reducing the strong fish odor that some indoor gardeners find unpleasant. Nutritionally, both provide a 5‑1‑1 ratio, but the deodorized formula may be more comfortable for indoor use. If odor is a concern, the deodorized product is the preferable choice.

The Pennington Alaska Morbloom gallon provides the lowest cost per ounce, making it economical for regular feeding of a medium garden. The Alaska 5‑1‑1 115 oz container also offers good value, especially for those seeking OMRI certification. Compare the total price and the number of applications you expect to determine the best fit.

All listed products are formulated to be gentle and “will not burn” the foliage, which is important for delicate species. However, some items, like the Central Garden Brands fertilizer, highlight a vitamin blend that may be unnecessary for certain plants, though it is still safe. Always follow label directions and start with a diluted application to gauge plant response.

Check for clear labeling of the N‑P‑K ratio, OMRI certification, and any odor‑control claims such as deodorization. Packaging size matters: larger containers reduce cost per ounce but require proper storage to keep the product fresh. Also, verify that the bottle has a secure, resealable cap to prevent spills.

Yes, the 0‑10‑10 formula is a balanced nitrogen‑free fertilizer that promotes strong root and flower development, making it suitable for vegetables, fruits, and ornamental species. Its high phosphorus and potassium content supports blooming and fruiting, while the lack of nitrogen reduces the risk of overly leafy growth. Apply according to the recommended schedule for each plant type.

A single‑quart bottle is convenient for testing the product or for small garden beds, while a multi‑pack offers a discount per unit and ensures you have enough supply for larger or multiple garden areas. If you plan regular fertilization throughout the growing season, the multi‑pack provides better value and reduces the need for frequent re‑ordering. Consider your garden size and how often you will apply fertilizer.
