Bone Meal 3-15-0 for Root Strength and Early Growth
Down To Earth™ Bone Meal 3-15-0 is a phosphorus-rich, organic bone meal fertilizer designed to drive explosive root development and vigorous early season growth in demanding crops. With a 3-15-0 analysis plus 18% calcium, this granular amendment helps young plants establish quickly, making it ideal for transplants, bulbs, trees, shrubs, raised beds, and container gardens. Phosphorus supports both root and bloom development, so growers see stronger root systems, bigger blossoms, and improved overall plant health in soil or soilless media.
Organic Phosphorus and Calcium for Bulbs, Flowers, and Roots
As an all-natural phosphorus fertilizer, Bone Meal 3-15-0 helps plants take to new soil by stimulating dense, fibrous root systems that can access more water and nutrients. The added calcium helps build strong cell walls, supporting sturdier stems and improved resilience under high-performance growing conditions. Use it when planting bulbs for reliable emergence and large, showy flowers, or side-dress root crops like carrots and potatoes for increased size and quality. DTE™ Bone Meal 3-15-0 is one of those essential organic soil amendments every serious grower likes to keep on hand for transplants, bloom initiation, and long-term soil fertility.

| Application Rate | Instructions |
|---|---|
| Bulbs | Add 1 tbsp per hole for average size bulbs, more for larger varieties. Mix thoroughly into soil and water in well. |
| Containers | For new plantings, add 1–2 tbsp per gallon of soil and mix thoroughly OR add 2.5–5 lbs per cubic yard. For established plants, lightly mix 1–2 tbsp per gallon into the soil surface once each month during the growing season. |
| Row Crops / Acreage | Apply 500–1,000 lbs per acre depending on specific crop needs or required pounds of actual nutrients per acre. |
| Vegetable Gardens & Flower Beds | To prepare new gardens, apply 2.5–5 lbs per 100 square feet and thoroughly mix into the top 3" of soil. For new transplants, add 1–2 tbsp per hole, mix into soil and water in well. To feed established plants, side dress 2–4 oz once each month during the growing season to promote fruiting and flowering. |
| Trees & Shrubs | Spread 1 lb per 2" of trunk diameter around the base outwards to the drip line, mix into soil surface and water in well. For new trees, prepare transplant hole and mix 1–2 cups with the backfill soil. Use the amended soil to fill in around the new tree and water in well. |
Notes: 2 cups ≈ 1 lb; ½ cup ≈ 4 oz; 1 tbsp ≈ 0.5 oz
