Down to Earth Fish Bone Powder 4-20-0 | 1lb - (Case of 6)

Concentrated Free-Flowing Phosphate Powder from Enzymatically Processed Fish Bone, 1lb

A concentrated phosphorus source that's also fine and free-flowing is harder to find than a standard granular bone meal, which can clump and blend unevenly into custom mixes. Down To Earth Fish Bone Powder 4-20-0 processes fish bone through enzymatic hydrolyzation into a fine, free-flowing powder with roughly double the phosphorus concentration of standard Fish Bone Meal, suited to precise phosphorus supplementation or deficiency correction.

The 1lb bag, sold as a case of six, is convenient for growers applying Fish Bone Powder in targeted amounts to containers, raised beds, or individual plants showing phosphorus deficiency.

Frequently Asked Questions

How is Fish Bone Powder different from Fish Bone Meal?

Fish Bone Powder carries a higher phosphorus concentration (20% versus 12% in Fish Bone Meal) and is processed into a finer, free-flowing powder through enzymatic hydrolyzation. It's designed for more precise phosphate supplementation than the coarser meal form.

What plants can Fish Bone Powder 4-20-0 be used on?

It's suited to all plant types, including vegetables, flowers, herbs, trees, shrubs, and vines, wherever supplemental phosphorus is needed. It works as a targeted amendment rather than a complete fertilizer.

How does phosphate support plant development?

Phosphate is an essential macronutrient involved in energy transfer, root development, and reproductive growth including bud set, flowering, fruiting, and seed production. Adequate phosphate supports these processes across nearly all plant types.

How is Fish Bone Powder applied?

It can be incorporated into growing media at planting, worked into soil, or applied as a targeted amendment once a phosphorus deficiency is identified. Follow the current label for rates by plant type.

Is Fish Bone Powder 4-20-0 OMRI Listed?

This particular fish bone powder isn't labeled OMRI Listed. If certified organic status matters for your program, check the current product packaging or consider Down To Earth's OMRI Listed Fish Bone Meal as an alternative phosphorus source.
