Phosphorus is among the essential nutrients needed by plants to grow with vitality. Aside from aiding roots in their absorption of water, it also helps produce the plant’s energy unit.
With that said, there’s no doubt that all plants need phosphorus to thrive. And when it comes to fertilizers with a high phosphorus content, you can always rely on bone meal garden fertilizers.
Bone meal garden fertilizer is a type of fertilizer that’s made from crushed or powdered animal bones. Animal bones are an abundant source of phosphorus, making them a rich fertilizer once properly broken down into the soil.
If you want to know more about bone meal garden fertilizers, then you came to the right place. This article will introduce you to bone meal fertilizers, their pros, and cons, and enumerate the five best bone meal garden fertilizers in the market today. You’ll also learn how to use this type of fertilizer to make the most of it for your plants.
What Is Bone Meal?
Bone meal refers to a mixture made from defatted animal bones that have been crushed into pellets, granules, or powder. It contains high amounts of phosphorus and calcium, making it an excellent dietary supplement for animals and plants.
As a fertilizer, bone meal is considered a slow-release fertilizer since it takes a while to break down and be absorbed by the soil. It is also interesting to note that bone meal is not water-soluble. This means that it requires the soil to be acidic to be broken down properly.
Bone meal also contains low amounts of nitrogen, which aids in the photosynthesis of plants. With that said, there’s no denying that bone meal is an excellent fertilizer for your garden – especially if you have fruit-bearing and flowering plants.
Is Bone Meal a Good Fertilizer?
A bone meal is a good fertilizer. Bone meal contains phosphorus, calcium, and nitrogen – nutrients needed by plants in their daily processes to thrive.
It is known to strengthen roots, so it’s also the ideal choice for bulbs and root crops. Also, since it is a slow-release fertilizer, it delivers a steady flow of nutrients to the plants without burning the roots or overfeeding them.
Why Use Bone Meal for Plants?
There are a variety of reasons why you should use bone meal fertilizer for your plants. Aside from being a rich source of nutrients, bone meal is also organic.
This means that it doesn’t contain any chemicals, unlike most commercial fertilizers in the market. This reduces chemical pollution in the soil, and you can be assured that the produce is safe to consume.
Also, bone meal is usually in powder or granulated form. That makes them easy to mix with soil, so spreading it across your garden won’t be a problem.
What Garden Plants Like Bone Meal?
Bone meal fertilizer will benefit all plants. But considering its high phosphorus content, it is especially beneficial to flowering plants and root crops.
Specifically, flowering plants such as tulips, lilies, and roses have been observed to thrive when fed with bone meal. The same is the case for root crops such as carrots, onions, potatoes, radishes, and beets.
Benefits of Using Bone Meal Garden Fertilizer
Rich in phosphorus. Phosphorus helps harvest the sun’s energy and converts it into usable energy. Since the bone meal is rich in phosphorus, it’s a key component to ensure a strong root system for your plants. Phosphorus also helps with bloom and fruit production, so you’re bound to have a beautiful and bountiful garden.
High in calcium. Another benefit of using bone meal garden fertilizer is that it is rich in calcium. Bones have high calcium content, and this mineral helps strengthen cell walls to keep the plant free from pathogens.
Slow and steady delivery of nutrients. Bone meal fertilizer is a slow-release fertilizer. This means that it takes a while to decompose, and even by the time it has decomposed, it feeds the roots with just the right amount of nutrients so as not to cause overfeeding. This also ensures that the fertilizer won’t burn the roots.
Low waste. Bone meal garden fertilizer also benefits the environment by reducing waste. Instead of throwing out discarded bones from meals or slaughterhouses, crushing them as bone meal helps reduce environmental waste while also promoting plant growth.
Drawbacks of Using Bone Meal Garden Fertilizer
By itself, it is not balanced. Bone meal garden fertilizer is high in phosphate and calcium, but it only contains little nitrogen and usually no potassium. If your plant needs all other essential nutrients, you have to mix your bone meal with other fertilizers to balance it out.
May attract scavengers. Bear in mind that bone meal fertilizer is made of crushed animal bones. This has a strong scent that, if not properly mixed with soil, may attract scavengers. This will leave you with a garden with a dug-up plot and pulled-up plants.
Slow release. Another drawback of bone meal fertilizers is that it is not fast-release. This means that it takes months to decompose, so it is not instantly absorbed by the roots. If you need your fertilizer to be absorbed immediately by your plants, then the bone meal should not be in your options.
Not compatible with all soil types. It must also be noted that bone meal is not water-soluble. This means that it can only be broken down when the soil is slightly acidic. Thus, it will work only if the pH level of your soil is below 7.0.
How to Use Bone Meal Fertilizer?
To make the most of your bone meal fertilizer, you must know how to use it properly. That depends on where your seeds are planted.
1. Using bone meal fertilizer on garden beds. When it comes to using bone meal fertilizer directly on your garden bed, a good rule to follow is to spread one pound of bone meal for every ten square feet of soil.
With a spreader like the Scotts Whirl Hand-Powered Spreader, you start by sprinkling the area with fertilizer and make sure that the entire area is covered. Then, you mix it into the soil to make sure it is spread evenly.

Mixing the bone meal into the soil not only pushes it down to be at the roots level once the seeds are planted, but it also masks its scent to avoid scavengers.
2. Using bone meal fertilizer on containers. Since containers are more compact, the ideal ratio is one tablespoon of bone meal per planting soil.
Then, you can use a trowel like the Fiskars 384220-1001 Ergo Garden Hand Trowel to mix the fertilizer thoroughly into the soil. Now your seeds are ready for planting.

How to Make Bone Meal Fertilizer at Home?
By making your bone meal fertilizer at home, you’re assured of the quality of the materials that go into your fertilizer. Fortunately, it’s easy to make bone meal fertilizer from home. Just follow the simple steps below and you’re good to go.
Step 1: Collect the bones. The first step is to collect the bones you will be using for your bone meal fertilizer. You may either buy bones from slaughterhouses or use the ones you have collected from your previous meals.
To make bone meals at home, stick to smaller bone pieces, such as those from chicken or turkey.
Also, if you intend to produce a lot of bone meal fertilizer, make sure to collect a lot of bones because once you’re done with the entire process, you won’t have a lot left.
Step 2: Prepare the bones. Once you have collected the bones, you have to clean them thoroughly to make sure only the bone remains. If the bones still have meat and marrow, these may delay their decomposition. As a result, it may not break down in time for the growth of the roots.
Once you’re done cleaning the bones, you should also boil them for about an hour. The heat from the boil will not only separate the meat from the bones, but it will also melt the marrow away from the bones.
Step 3: Dry the bones. After you’re done cleaning the bones, it’s time to let them dry. Once the bones are dry, grinding them into smaller pieces will be easier.
To dry the bones, bake them in the oven for three hours. If you used bigger bones, you may have to bake them for longer periods. Also, make sure the oven has been preheated to at least 284°F to make sure it dries out thoroughly.
Step 4: Break and crush the bones. Once the bones are dry, you can now break them into smaller pieces. You can do so with a metal mallet like the AOWOTO Meat Tenderizer Hammer Mallet.

But before you do so, make sure that you sterilize the surface before placing the bones there. Otherwise, you might contaminate the bone meal.
Once you’re comfortable with the size of your bone meal, you can start grinding them into smaller granules or even into fine powder. The end product all depends on your preference.
If you used small bones, you may opt to grind the pieces manually with a mortar and pestle. The ChefSofi Mortar and Pestle has a 2-cup capacity which is enough for small bones,

Can Bone Meal Be Used on All Plants?
Bone meal fertilizer can be used on all plants. It is especially useful to flowering and fruit-bearing plants and trees due to its high phosphorus content.
Will Bone Meal Pollute Water Sources?
A bone meal may pollute water sources, but only if it is used in high amounts. In this case, it may cause nutrient pollution to water sources. However, bone meal is usually applied in minimal amounts so plants can absorb them without the excess seeping into water sources.
Is Bone Meal Fertilizer Toxic?
Bone meal fertilizer is not toxic. However, if it is ingested by animals and humans in large quantities, it may lead to gastrointestinal issues.
Can Too Much Bone Meal Kill Plants?
Too much bone meal may cause harm to your plants. While it may not instantly kill your plants, it may lead to overfertilization which causes stress to your plants.
When a plant is fed with too much phosphorus, it may suffer from stunted growth – which is the opposite of what you are aiming for.
