If you’re new to veganic gardening and searching for alternatives to blood, bone and other so-called “organic” fertilizers, then this list of eco-friendly soil amendments will strengthen and support your green thumb.
Making or purchasing a nutrient-rich mix of vegan organic fertilizers to help your garden thrive is a simple and sustainable way to enrich your soil without compromising your ethics.
I’ve organized this list of veganic fertilizers into the following categories:
- Ready made (those that you can find in your local store or online)
-Low cost (cover crops, Epsom salts, etc., that require a small purchase, but are worth the output)
- Free and fabulous (what you’ll find in your backyard, or compost bin)
- Fertilizers to use sparingly
So let’s get gardening!
Next: Ready made stock-free fertilizers
If you’re interested in simplifying the process and picking up a pre-made fertilizer blend, then I’ve listed a number of veganic products you can find online or at your local garden store below:
Warning: Most of these companies are not strictly vegan, so read the labels and if it doesn’t have a vegan organic guarantee it’s best to pass.

VeganSea Water Soluble Seaweed Powder
This product is also the perfect soil amendment for addressing soil deficiencies, and it has a multitude of other benefits as well. Among these are that it will help create an environment in the soil that will help plants survive frost and drought conditions, and because it raises the sugar levels in plants it helps prevent and treat insect and disease problems. It is also the perfect product to use when transplanting because it will help prevent shock and will promote rapid root development.

Low cost vegan organic fertilizers
These stock-free fertilizer alternatives are cheaper than buying a pre made mix, but do require an initial investment.
Green Manures, Nitrogen-fixing crops
You might have to spend a small amount of money to get this crop growing, but it’s worth the reasonable investment. Fast-growing plants, such as wheat, oats, rye, vetch, or clover, can be grown as green manure crops before your standard planting, and then tilled into the garden as you ready the beds. Green manure crops absorb and use nutrients from the soil that might otherwise be lost through leaching, then return the nutrients into the soil when they are tilled under. The root system of cover crops also helps improve the soil structure and prevent erosion. Vetch, peas, broad beans (fava beans), and crimson clover are known as nitrogen-fixing crops because they are particularly good at bringing this nutrient back into the soil when they are tilled into the bed. Adding cover crops to your garden during fall and winter will also help reduce weed growth.
Alfalfa meal, Flax Seed Meal, Cottonseed Meal and Soya Meal
All excellent sources of nitrogen.
An excellent source of magnesium.
Seaweed (fresh, liquid or meal)
Often used for its trace elements, seaweed is best when harvested fresh from the sea (as opposed to washed up and sitting on beaches.) Some veganic gardeners use bulk kelp meal or spirulina instead (which are sources of potassium and trace minerals).
EM or other Beneficial Micro Organism
Beneficial micro organism work harmoniously with plants to increase nutrient availability in the soil, root formation and insect resistance.
Next: Free fertilizers
Free vegan organic fertilizer
These are my favorite fertilizers because you can create them in your own backyard! I try to use a mix of these soil amendments first, and then add additional veganic ingredients such as wood ash, or spirulina if needed.
Every good gardener has a great compost pile (if they have the space.) If you’re just beginning, I’ve got a good guide to compost to help you get the most out of your kitchen/yard scraps. A good compost pile is full of wonderful nutrients, nitrogen and beneficial microorganisms to keep your garden going strong. Not only is making your own compost pile easy to do and a free way to feed your garden, it also encourages a strong worm population which is wonderful for your plants.
Vermiculture or Vermicastings (Worm Castings)
Worm castings improve the soil structure and increase fertility. They can be added to your garden without purchasing them from a store (which is potentially harmful to the worms being cultivated for the product), by simply providing the right environment for the worms to thrive in. Re-establishing the natural worm populations in your garden is as easy as providing a cool, damp and dark environment with plenty of nutrients for them to enjoy (compost pile/hay mulch.) If you’re interested in increasing your worm population this link will help you get started.
Mulching is simply covering the ground with a thick layer of organic material. Mulching will not only feed the soil as it breaks down, but will also suppress weeds and encourage worms in your garden. You can do this while plants are growing (as long as you don’t overwhelm the plants) or you can apply mulch when you’re shutting down your garden for the winter.
You can make wonderful liquid fertilizers with comfrey or nettles and other composting plants. These fertilizers are nitrogen rich, can often be created for free, and your garden will love them. Here are some directions on how to make your own nettle or comfrey compost tea.
Next: Veganic fertilizers to use sparingly
Vegan organic fertilizers to use sparingly:
While all of the fertilizers below are stock-free and valuable, they are obtained through mining, so we use them very sparingly or not at all. They are valuable soil amendments though, so if there is a particular deficiency in your soil, which these products will rectify, attempt to use them in small quantities.
You’ll also notice that a number of the ready-made mixes contain some of the ingredients listed below. So if you do choose to purchase a prepackaged mix, make sure to use it sparingly and supplement with compost and other sustainable soil amendments.
A source of calcium and magnesium, it is also used to help break up heavy clay soil. Calcium is essential for strong plant growth and aids in the intake of other nutrients. Lime can be used to raise the pH level, if your crop requires this.
Gypsum (hydrated calcium sulfate)
Gypsum adds calcium to the soil without raising the pH.
A finely ground rock dust and prized source of calcium and magnesium.
Prized for its high phosphorus content, the primary mineral in phosphate rock is apatite.
Rock Dusts (or Stonemeal)
Containing a blend of different powdered rocks, when mixed with the soil its mineral content is slowly released, revitalizing overworked soils and stimulating microbial activity.
Used as a soil amendment and fertilizer, it has the consistency of sand but 10 times the moisture absorption. Green Sand is mined from deposits of minerals that were originally part of the ocean floor. It is a natural source of potash, along with iron, magnesium, silica and as many as 30 other trace minerals. It may also be used to loosen heavy, clay soils.
Potassium enhances flower and fruit production and helps harden up foliage, making it less susceptible to disease. Rock potash is very slow-acting (it may take years to fully release its minerals). Because the potash is released gradually as the mineral weathers, it is usually used when preparing the soil for planting.
Contains some potassium, phosphate and trace amounts of micro-nutrients such as iron, manganese, boron, copper and zinc. It can have an alkalizing effect on the soil, which many plants do not like, so use it sparingly.
