Down to Earth Bone Meal 3-15-0 | 25lb - OMRI Listed

High-Phosphorus Bulb and Flowering Plant Amendment, 25lb

Flowering and fruiting plants lean heavily on phosphorus at the wrong moments to correct with a quick fix, since phosphorus deficiency shows up as poor bloom and root development rather than an obvious leaf symptom. Down to Earth Bone Meal 3-15-0 is built around a high-phosphorus, calcium-supporting ratio specifically for flowering plants, trees, ornamentals, and bulbs at planting.

This 25lb bag suits home gardeners planting multiple beds of bulbs or flowering plants across a season.

Key Features & Benefits

• High-phosphorus 3-15-0 ratio — concentrates on phosphorus and calcium rather than nitrogen, matching what flowering and rooting plants need most.
• OMRI Listed — cleared for certified organic bulb and flower production.
• Calcium alongside phosphorus — supports structural plant development in addition to the flowering and root benefits phosphorus provides.
• Bulb planting use — suited to working into the planting hole for bulbs to support early root development and season growth.

Who Should Use This

Gardeners planting bulbs, flowering plants, trees, or ornamentals who want a phosphorus-forward feeding at planting time, rather than a general all-purpose blend, are the right fit for Bone Meal.

Frequently Asked Questions

Why does Bone Meal use a high-phosphorus ratio instead of a balanced NPK?

The 3-15-0 ratio is weighted toward phosphorus and calcium because flowering, fruiting, and root development lean more heavily on those two than on nitrogen. A balanced all-purpose blend would under-deliver on exactly what bulbs and flowering plants need most at planting.

When should Bone Meal be worked in for bulbs?

It's typically mixed into the planting hole at the time bulbs go into the ground, so phosphorus and calcium are positioned right where new roots will develop. Follow current label directions for the rate per bulb or per planting area.

Is Bone Meal 3-15-0 OMRI Listed?

Yes, this bone meal is OMRI Listed, meaning it has cleared review for use in certified organic growing. Confirm the listing shown on your package matches what your certifying body currently requires.

What plants benefit most from Bone Meal?

Flowering plants, trees, and ornamentals benefit from its phosphorus-and-calcium profile, and it's also a common choice worked into the soil at bulb planting time. It's less suited as a general all-season feed than as a targeted planting-time amendment.
