Black Swallow Bone Meal (4-10-0) – 2KG

Black Swallow Bone Meal (4-10-0) – 2KG

Bone meal, from a bovine source, has been used in gardens as a phosphorus and calcium source, coming in at around 15% phosphorous and It is sourced from bones that are steamed, dried, and ground down. It can be more readily accessed by the plant roots than a colloidal phosphate [soft rock phosphate], but works best in conjunction with a good mychorizal product. For this reason, it works best in soil that has a ph of 7.0 or below- much over this and the phosphorous in the bonemeal cannot be accessed. Bone meal also provides a source of calcium for your soil.

Application

As a general rule, use bonemeal at one tablespoon per planting hole, especially at transplanting time. Alternatively, you can apply 1 pound for every 10 sq ft of soil surface.

In potting soils and mixes, use at 1/2 cup per cubic foot of mix.
