10 DIY Succulent Fertilizer Recipes: The Ultimate Guide to Healthy Succulents

Imbalanced Fertilizer

Soil that’s too acidic or low in nutrients can cause your plants to grow more leaves and stems but less roots and flowers. This is called “nitrogen deficiency.”

The opposite is called “nitrogen overabundance,” which means that there’s not enough nitrogen in the soil for healthy growth of roots and flowers.

NPK Ratio

You’ll want to use succulent fertilizer with a balanced blend of NPK (nitrogen, phosphate, potassium) levels so that each type of plant has what it needs!

When you’re looking at a succulent food label, there will be 3 numbers that indicate the NPK ratio, so pick one with the same numbers like 10-10-10.

How Much Fertilizer

Use only half the recommended amount of succulent food at first and gradually increase the amount if necessary. If your plant is growing slowly or shows no signs of growth, try increasing the dose again until you find a dosage that works for your plant.

If you’re looking to add more nutrients than just nitrogen(N), phosphorus (P) and potassium(K), look into using other types of succulent food with nutrients such as magnesium (Mg) and calcium (Ca). These elements can help strengthen root systems so they grow stronger over time—a great way to make sure they don’t get lost in all that dirt!

Also be careful not let too much succulent fertilizer touch the leaves; this could lead them toward nutrient burn which means losing all their leaves.

How often do you fertilize succulents?

Succulents don’t require frequent fertilizing. In general, they only need fertilizer during their active growing season, which is typically spring and summer.

Most succulents only need to be fertilized once every 4 to 8 weeks during the growing season. Some sources recommend fertilizing every other watering during the peak of the growing season.

Can I use all purpose plant food for succulents?

Sure! Just make sure it can be diluted quite a bit or you can use a granular type of all purpose plant food which is usually time released and is slowly distributed throughout the soil over time.

My favorite type of commercial succulent fertilizer/all purpose plant food is a solid kind that I just mix into the soil called Osmocote. The nutrients are released slowly so as to not burn the succulents. You can find it here: https://amzn.to/3A5ih7a

SUPERthrive for Succulents

One very very popular liquid concentrate plant food is called SUPERthrive which has been used for decades to maintain plant health, reduce transplant shock and improve success with propagation. I use it mostly on my indoor plants, but whenever I have a succulent that just isn’t doing well and I can’t figure out why, I’ll look to SUPERthrive as my last ditch effort.

A little bit of it goes a long way too! The dosage for succulents and cactus is 1/4 of a teaspoon per 1 gallon of water. You can also use it every time you water, but I’d wait to see how your succulents react to it and adjust the frequency from there. It’s always available on Amazon and most garden retailers as well. The reviews speak for themselves, so have a look and try it out!

Compost/Compost Tea

Compost is an excellent source of slow-release nutrients for plants, including succulents. To use compost as an organic homemade succulent fertilizer for succulents, simply mix it into the soil around the base of the plant. The microbes and bacteria in the soil will take it from there. Another way you can use compost is to make DIY liquid compost tea. Keep scrolling for the recipe.

How to make organic compost tea:

2. Add compost to a burlap sack or cheesecloth bag and tie it closed.

5. Remove the bag of compost from the water and strain the liquid into a separate container.
6. The compost tea is now ready to use as a fertilizer for your succulents. Simply dilute the tea with water to the desired strength and use it to water the plants.

• Provides a slow-release source of rich nutrients to plants

Cons of Compost Tea:

• Can make the soil too dense if used in excess, leading to poor drainage and root rot in succulents

Eggshells

Eggshells are a natural source of calcium, which is important for strong cell walls and root development in plants.

To use eggshells as a DIY organic succulent fertilizer, first remove the membrane inside the shell, crush the shells into fine pieces and sprinkle around the base of the succulent or mix in with the soil.

Over time, the eggshells will break down and release calcium into the soil. The smaller the eggshell bits, the faster the calcium will be released into the soil.

Here are some pros and cons to keep in mind when using eggshells as a natural homemade succulent fertilizer:

Coffee Grounds

Coffee grounds are a rich source of nitrogen, which is important for leafy growth and healthy green foliage in plants. I love using coffee grounds as succulent fertilizer because I drink at least a pot of coffee every morning, so I might as well put those grounds to good use!

How to Use Coffee Grounds to Fertilize Succulents

Fish Tank Water

Fish tank water is a rich source of nutrients, including nitrogen, phosphorus, and potassium, which are important for plant growth. Personally, I think that fish tank water is the best fertilizer for succulents hands down.

We used to have a 40 gallon fish tank and when I’d use fish tank water to water my succulents, they thrived like never before. It almost makes me want to keep another fish tank just for the water!

Fish tank or aquarium water makes an excellent DIY liquid fertilizer for succulents for a few key reasons:

• It contains nitrogen and phosphorus from fish waste and uneaten food, which are nutrients that succulents need. The nitrogen promotes healthy green growth and phosphorus aids in root development and flowering.
• The water is rich in minerals and trace elements from the fish food, gravel, coral, seashells, etc. in the tank. These provide additional nutrients succulents thrive on.
• The water already has a balanced pH since aquarium water is carefully monitored for fish health. This means it won’t make soil too acidic or alkaline when used as DIY liquid fertilizer water.
• Aquarium water is free of chlorine, chloramines, and other additives found in tap water that can build up in soil over time.
• Using tank water for plants when changing aquariums prevents it from going to waste while providing a free and natural fertilizer source.
• The mild nitrogen concentration of aquarium water reduces chances of fertilizer burn compared to stronger synthetic fertilizers.

So by occasionally using used fish tank water to water succulents, it feeds them a variety of vital nutrients and minerals tailored to plant health. This leads to stronger, healthier, and more vibrant succulents. You’re changing your aquarium water regularly anyways…. right!?

How to Use Fish Tank Water to Fertilize Succulents

To use fish tank water as a DIY liquid succulent fertilizer, simply dilute it and use it to water your succulents. You would think it could make the soil stinky because fish, but that isn’t the case at all.

Egg Shell Powder and Bonemeal Rooting Fertilizer

This succulent fertilizer uses naturally mineral-rich ingredients to promote healthy root development in succulents. The powdered egg shells and bonemeal release calcium and other micronutrients into the soil over time.

Ingredients:

• 1 cup eggshell powder
• 1/2 cup bonemeal powder
• 1 cup water

Instructions:
Grind egg shells into a fine powder. Mix with bonemeal and water to form a paste. Store in an airtight container.

Pros of Egg Shell Powder and Bonemeal:

• Encourages sturdy root growth and plant structure
• Slow-release formula means infrequent applications needed
• All-natural and organic ingredients are safe for plants
• Provides minerals succulents need for photosynthesis

Cons of Egg Shell Powder and Bonemeal:

• Must prepare ingredients by grinding and mixing
• Not a complete fertilizer, so may need supplemental nitrogen
• Little research on its effectiveness on succulents specifically
• Bonemeal can raise soil pH in very alkaline-sensitive plants

This homemade succulent fertilizer aims to nourish roots organically. While mineral-rich, it lacks nitrogen and may need supplementing. Its benefits would depend on individual succulent needs and soil chemistry. Commercial fertilizers may provide a more balanced meal but if you already have the ingredients why not use them instead of letting them go to waste!
