When you need to add phosphorus to the soil in your garden, many organic gardeners turn to bone meal fertilizer for plants.
This is a highly effective and natural garden soil amendment that can work wonders for your plants.
After all, plants that are deficient in phosphorus tend to have a hard time forming strong roots and growing the way they should.
If you’re curious about how to use bone meal for soil plants, you’ve come to the right place. This guide will tell you everything you need to know.
What Is Bone Meal Fertilizer?
Bone meal fertilizer is pretty much exactly what it sounds like. This organic fertilizer can be a fine powder or a meal, but either way, it will be made up of ground-up animal bones, often beef bones.
Normally, those bones will be beef, but it can be any type of animal that’s commonly slaughtered.
Bone meal fertilizer is usually steamed to help release nutrients and make them more readily available for plants to use.
Steaming the bones also helps to sterilize them to prevent spreading pathogens. In addition to being sold as a meal or a fine powder, bone meal can also be made into a liquid or pellet.
It’s often confused with blood meal, but bone meal contains no blood and supplies phosphorus rather than nitrogen (something that blood meal is famous for).
What Is Bone Meal Good For In The Garden?
Bone meal provides a huge boost of phosphorus, which is absolutely essential for the organic gardener. It’s loaded with other vital nutrients as well.
For example, it is also rich in calcium and nitrogen. It’s perfect for bulbs and other flowering plants. Environmentally friendly and organic, bone meal is easy to apply to the garden and relatively affordable, too.
In addition to phosphorus, bone meal provides nitrogen and calcium. Using bone meal in the garden can result in higher yields of fruits and seeds along with a better root structure for newly developing plants.
It can encourage beautiful and healthy blooms and improve the disease and pest resistance of your plants.
Can You Use Too Much Bone Meal For Plants?
There are very few drawbacks associated with using bone meal fertilizer, but as with any fertilizer, moderation is key. Since it is not 100% balanced, you’ll want to apply a different fertilizer along with the bone meal if your plants need other nutrients besides phosphorus. You should never attempt to grow a plant from seed to harvest using bone meal alone.
Not only that, but it’s important to remember that bone meal fertilizer is made out of - well, bones. Because of this, if it isn’t mixed into the soil properly, it can attract pests and scavengers with its smell.
You should also make sure you store your extra bone meal securely where animals can’t reach it. Another thing to consider is that this fertilizer is slow release. It won’t provide your plants with an immediate boost of nutrients and it will not serve as a quick fix. It’s only effective in soils with a pH level lower than 7, as alkaline soils limit nutrient uptake, so that’s something else you’ll want to keep in mind.
Using too much bone meal can force other nutrients out of your plants, too, like zinc and iron. It can cause your plants to turn yellow and harm their chlorophyll production if you aren’t careful about supplying other nutrients when they are needed, too.

What Soil Grown Plants Benefit From Bone Meal Fertilizer?
Almost all soil-grown plants benefit from bone meal, but some more so than others. All plants rely on phosphorus to help them grow, produce fruit and flowers, and engage in photosynthesis.
Without phosphorus, your plants simply cannot live. There are some plants that benefit from this fertilizer more than others. Consider adding bone meal fertilizer to flowering plants like amaryllis or roses. You might also add it to alliums like leeks, onions, and garlic.
It’s also often used to help establish lawns, as it helps grass plants develop a stronger root structure. It can even be used on tomatoes - it’s one of the best amendments you can add to provide the calcium your plants need to form fruits.
Using Bone Meal For Soil Plants - What Every Grower Needs To Know
Using bone meal for plants in your garden is simple. Most often, you’ll use it to increase phosphorus. This fertilizer has an NPK nutrient profile of 3-15-0 on average.
The added phosphorus will help your plants flower and since it's so readily available in bone meal, it will be easy for your plants to take up quickly. This makes it the perfect addition for fertilizing plants like roses. But when it comes to learning how to use bone meal for plants in the garden, you need to consider how you're going to use it.
Whether you use it as a soil amendment at the start of the growing season, a fertilizer during flower, or as a root drench periodically - we're going to teach you everything you need to know.
Bone Meal For Plants As A Soil Amendment
Before you decide to use bone meal for plants, be sure to have your soil tested. If your pH level is higher than 7, this fertilizer won’t be as effective, so you’ll want to alter the soil pH level before starting.
Once you’re sure that bone meal fertilizer will be effective - and that phosphorus is actually needed - you should add the fertilizer at the rate of 10 pounds per every 100 square feet to use it as a general soil amendment.
It will release slowly over a period of four months. If you’ve recently added a high-nitrogen soil amendment to your garden, like rotted chicken manure, it can also be used to help balance things out.
By mixing the two together or applying one shortly after the other, you can get a more balanced blend of nutrients for your plants.

Bone Meal For Plants As A Fertilizer
When you are applying bone meal to spring-blooming plants like bulbs, apply about half a teaspoon when you plant in the fall and simply scratch it into the soil around the plant. You can supplement again in the spring.
You can also apply bone meal as a slow-release fertilizer to plants that are already in the ground. To do this, sprinkle the fertilizer and then rake it over the soil near your plants. When you add bone meal for plants as a fertilizer, be sure to lightly water afterward so the product can start breaking down.
You also need to pay attention to what other nutrients your plants are getting, as they'll likely develop potassium and nitrogen deficiencies if you don't give them other organic fertilizer sources. Apply the fertilizer when conditions are dry and you are able to work it into the top layer of soil.

Bone meal fertilizer can even be used as a tea or root drench. Liquid bone meal fertilizer is perfect for hydroponics. Wondering how to make bone meal tea? It's not very difficult.

How To Make Bone Meal For Plants
Learning how to make bone meal for plants can be a bit tricky if you don't have the right resources. Fortunately for you, we've compiled a step-by-step guide on how to make bone meal quickly and easily!
If you don’t want to learn how to make bone meal for your soil plants, you can always buy it. But, here is how to make bone meal for plants.
Start by gathering some scrap bones that you may have leftover from dinner. You can often get a good deal on these from your local butcher, too. Remove as much of the meat and fat as you can from the bones. This can slow the decomposition of the material and make it harder for you to get a good meal.
Place the bones in a pot of boiling water for one hour to make this process a bit easier. Then, preheat your oven to about 300 degrees. Place the bones on a baking sheet and put them in the oven for three hours. This will dehydrate the bones to make it easier for you to grind them up and it will also kill bacteria, fungi, and other pathogens.
Then, on a sterilized hard surface (concrete is best), layout your bones. Pound the bones with a metal mallet, crushing them into smaller pieces.
After this, you will likely need to use another grinding method to further process the bones. A mortar and pestle or stone grinder should do the trick. You can then use this powder as is or combine it with water or other nutrients for your homemade fertilizer mix.
