Bone Meal Fertilizer: When It Helps, When to Skip It, and How to Apply It
Bone meal can be useful for bulbs, roses, tomatoes and other flowering plants—but only when your soil actually needs phosphorus. This guide gives you a simple way to decide before you scoop.
2-14-0
Your soil is low in phosphorus and you want a slow-release source mixed into the root zone.
Your soil test already shows high phosphorus, or your soil is strongly alkaline.
Mix it into soil, follow the label, water after planting and keep it away from pets.
Do You Actually Need Bone Meal?
Many Canadian garden soils have already received compost or fertilizer for years. Adding more phosphorus “just in case” may do nothing for the plant and can create nutrient imbalances.
Is the soil below pH 7?
Bone meal phosphorus is more available in mildly acidic to neutral soil. Availability drops as soil becomes more alkaline.
Has this bed been fertilized often?
Regular use of manure, compost and bloom fertilizers can build up phosphorus over time. More is not automatically better.
If phosphorus is low, pH is suitable and you are planting for the season ahead, bone meal is a reasonable choice.
What Bone Meal Is—and What 2-14-0 Means
Bone meal is a sanitized, ground animal bone powder. It is mainly used as a slow-release phosphorus fertilizer, and it also contains a small amount of nitrogen.
What does 2-14-0 mean? It is the fertilizer grade on the bag. For J PLUS T Bone Meal, it means 2% nitrogen, 14% available phosphate and 0% potash.
Bone meal releases phosphorus slowly over time, so it is commonly used when planting bulbs, flowering plants, tomatoes and root crops. It is not meant to be a fast fix, and it is not a complete fertilizer for every plant.
Simple use tip: always mix bone meal into the soil instead of leaving it on the surface. This helps roots reach the nutrients and can reduce the chance of attracting pets or wildlife.
Where Bone Meal Works Best—and Where It Does Not
✓ Better situations
- New bulb, perennial or vegetable plantings in soil that needs phosphorus
- Garden beds with mildly acidic to neutral pH
- Soil-based raised beds and large outdoor containers
× Poor situations
- Soil tests that already show high phosphorus
- Strongly alkaline soil, especially above about pH 7.5
- Hydroponic or water-soluble feeding systems
- Fast-growing leafy crops that mainly need nitrogen
| Soil situation | Likely result | Practical choice |
|---|---|---|
| Below pH 7 with low phosphorus | Bone meal is more likely to provide useful phosphorus over time. | Apply at the package rate and mix into soil. |
| pH 7 to 7.5 | Phosphorus availability may be reduced. | Use a soil test rather than increasing the rate on your own. |
| Above about pH 7.5 | Bone meal may provide little benefit. | Choose a soil-test-based nutrient plan; do not assume rock phosphate will solve it. |
| Phosphorus already high | Extra bone meal is unnecessary and may worsen nutrient balance. | Use a fertilizer that supplies only the nutrients you need. |
How Much J PLUS T Bone Meal 2-14-0 to Apply
New plantings
Mix the bone meal thoroughly with soil in the planting hole or backfill. Do not leave a concentrated layer directly against roots or bulbs.
Established plants
Spread around the base, keep it away from the stem or crown, and gently work it into the top layer of soil.
Measure instead of grabbing a handful
Use a dedicated garden spoon. One tablespoon is about 15 mL, but always follow the product label rather than converting by weight.
Mix it into the root zone
Phosphorus does not move easily through soil. Mixing it where roots will grow is more useful than leaving it on the surface.
Water after planting
Water settles the soil and starts the slow-release process. It also reduces loose product and scent at the surface.
Keep pets and wildlife away
Bone-based fertilizers can attract dogs, raccoons, skunks and other animals. Store the bag securely and do not leave the product exposed.

This visual shows the package directions for new and established plants, making it easy for gardeners to check the rate at a glance.
Apply at planting time. In Canada, that usually means spring transplanting after frost risk has passed or fall bulb planting before the ground freezes.
Remember that cold soil slows biological activity. Bone meal is a season-building amendment, not an instant bloom booster.
Using Bone Meal for Common Canadian Garden Plants
Use the same decision for every plant: check the soil, use the label rate and mix the product into the root zone.
Tulips, daffodils and alliums
Bone meal is most useful where phosphorus is actually low. Mix it into the surrounding soil rather than placing a pile directly under the bulb. Newly purchased bulbs already contain stored energy for their first bloom, so the benefit may be more noticeable in later seasons.
Tomatoes and peppers
Use 1–2 tablespoons per transplant only when phosphorus is needed. Bone meal supports nutrition; it does not guarantee more fruit, and it should not replace balanced feeding or consistent watering.
Roses and flowering perennials
For a new planting, mix the product through the backfill. For an established plant, work 2–4 tablespoons into the soil around the root area without piling it against the crown.
Root crops and raised beds
Phosphorus is essential, but extra phosphorus does not automatically produce larger roots. Test beds that receive compost regularly, because phosphorus can accumulate while nitrogen is still the nutrient that limits growth.
For containers: avoid adding bone meal repeatedly to small pots. Nutrients build up faster in limited soil volume. Use a measured rate, refresh the potting mix .
Simple rule: use bone meal only when you truly need extra phosphorus. Measure the rate, mix it into the soil and do not assume that “organic” means unlimited use.
Bone Meal Fertilizer FAQ
Quick answers to the questions Canadian gardeners ask most often.
What is bone meal fertilizer good for?
Bone meal is a slow-release phosphorus source. It can be useful for bulbs, flowering perennials, fruiting vegetables and new plantings when the soil needs phosphorus and the pH is suitable.
How long does bone meal take to work?
Expect gradual release over weeks to months rather than an immediate response. Moisture, temperature, soil pH, particle size and biological activity all affect the speed.
Can I use bone meal on every plant?
No. It is unnecessary where phosphorus is already adequate, poorly suited to hydroponics and incomplete as a stand-alone fertilizer. Leafy greens often benefit more from appropriate nitrogen than extra phosphorus.
Can bone meal burn roots?
Bone meal is slow-release, but any concentrated amendment should be used carefully. Mix it thoroughly with soil and follow the label instead of placing a mound directly against roots or bulbs.
Does bone meal prevent blossom end rot?
Not reliably. Keep tomato soil evenly moist, avoid root damage, mulch the surface and avoid excessive nitrogen. Adding calcium or magnesium without a confirmed deficiency may not help.
Will bone meal attract animals?
It can. Dogs, raccoons, skunks and other animals may be attracted to bone-based fertilizers. Mix it into soil, water afterward, store the bag securely and keep pets out of the treated area.
Is bone meal vegan?
No. Bone meal is made from animal bone. Gardeners who avoid animal-derived inputs can choose a different phosphorus source based on soil-test recommendations.
Can I lower soil pH with sulphur and then add bone meal?
Soil acidification is slow and depends on soil texture, buffering capacity and the amount of change required. Do not add sulphur simply to make bone meal work. Test the soil first and use a rate recommended for your conditions.
