Know before you buy
Fish bone meal is a marine-based alternative that provides a similar nutrient profile but is sourced from fish rather than land animals. It is an excellent choice for gardeners who prefer to avoid by-products from traditional livestock farming.
The 4-12-0 ratio indicates that this fertilizer contains 4% nitrogen and 12% phosphorus, with no added potassium. The high phosphorus content is specifically designed to support strong root systems and encourage more robust flowering and fruit production.
Yes, this product is OMRI listed, meaning it has been reviewed and approved for use in certified organic gardening practices. It is made from all-natural ingredients without synthetic additives.
This formula is particularly effective for flowering plants, fruit-bearing trees, shrubs, and vegetable gardens. It is also highly beneficial when preparing new garden beds or planting bulbs, as it helps establish a strong root foundation.
For best results, mix the granules into the soil when preparing new beds or apply it directly into the planting hole when setting out bulbs or new shrubs. Because it is a slow-release organic fertilizer, it works best when incorporated into the root zone rather than just applied to the surface.
