DIY Fertilizer Recipes

The list below contains different DIY garden fertilizer recipes. Some can be used for general gardening while others are more for specific circumstances.

 

Compost

I’ll start out with compost because it is one of the most useful things you can do for garden soil. But, unlike the others below, making your own compost will take quite a while.

So, if you’re looking for something faster, choose from the other DIY fertilizer recipes below. However, do note that most of the fertilizer recipes below serve specific uses.

In any case, to create your own compost, you’ll need to collect kitchen and garden scraps. These are the browns (rich in carbon, usually carbohydrate rich materials) and greens (rich in nitrogen, usually proteins).

Compost Bin

  1. Slowly collect the nitrogen-rich and carbon-rich materials from the scraps you already have. This includes grass clippings, leaves and other items. To learn more about the different composting ingredients, check out my complete composting guide.
  2. Add water every so often while making sure to allow enough air to circulate in your compost pile.
  3. Over time, the compost pile will heat up and breakdown the materials until they become dark, crumbly soil-like texture.
  4. You can use this as compost to improve garden soil.

 

DIY Epsom Salt Fertilizer Recipe

In addition to Epsom salt’s health benefits, you can also create a DIY Epsom salt fertilizer recipe. Here’s one that works.

  1. Add 1 tablespoon of Epsom salt in 1 gallon of water
  2. If you need more or less just adjust the amount while keeping the same ratio
  3. Allow the Epsom salt to dissolve

Organic Tea Fertilizer

Here’s something that is perfect as an alternative to fertilizer. it is more complicated compared to many of the other recipes in our list. So, I suggest having all the ingredients and items prepared beforehand.

Here’s what you need:

  • ¼ cup of Epsom salt
  • 2 cups of urine (Yes, urine is high in nitrogen so it does help with plant growth. But, don’t use it without diluting it otherwise, you’ll end up with bald and brown spots in your yard much like the areas where your dog pees on. That’s because undiluted urine’s nitrogen concentration is too high.)
  • 2 cups of ash
  • 5 gallons worth of grass clippings
  • 5 gallon bucket

How to Make Organic Tea Fertilizer

  1. Combine the urine with the Epsom salt
  2. Mix the combination into the ash
  3. Then place everything in a 5 gallon bucket
  4. Fill the bucket with grass clippings
  5. Add water until it is close to the top
  6. Leave the tea to steep for 3 days
  7. Strain the tea
  8. Then dilute the strained tea mix by half with water

This is your organic tea fertilizer. You can apply it directly to the soil around your plants.

Vinegar Fertilizer

Vinegar

Vinegar is something every household should have.

In the kitchen you can use it for cooking, creating flavors or to cut through the thickness of certain sauces. It is also a handy ingredient you can use for all sorts of cleaning tasks.

In the garden, you can use it to increase soil acidity levels, which will keep acid loving plants happy.

Here’s how to create this DIY vinegar fertilizer recipe.

  • Combine a tablespoon of white vinegar with a gallon of water.
  • Place the solution in a watering can or container that makes it easy to pour onto soil.
  • Add the solution around acid loving plants if you need to increase soil pH levels
  • Use once every 3 months

This vinegar fertilizer solution works very well if you need to boost soil pH on a budget. But, be careful not to overdo it. Too much acid does more harm than good. As such, never use the vinegar straight. Instead, always make sure to dilute it first.

 

Egg Shell Fertilizer

Eggshells

We eat eggs regularly for breakfast. And, if you do too, you may want to think twice before throwing the used eggshells away.

You can create this Egg Shell fertilizer recipe instead. It can be used in place of lime to adjust soil pH when needed.

This eggshell fertilizer recipe will help you increase soil pH when needed without having to go buy agricultural lime. Thus, saving you money in the process.

Here’s how to make it at home.

  • Leave them out to dry.
  • When dry crush the shells until they’re get to a fine powdery consistency. You can use a blender or mortar and pestle.
  • Sprinkle the eggshell fertilizer powder around the plants on soil that need pH modification.

This eggshell fertilizer recipe works because eggshells contain calcium carbonate. This is the main ingredient in store bought lime.

 

Fireplace Ash Fertilizer

In case you live in a cold climate region and use a fireplace, don’t throw way the ash that accumulates after the wood has burned off.

As strange as it sounds, you can actually use fireplace ash in the garden as fertilizer. Another option is to use it as garden lime.

Here’s how to use it.

  1. Allow the ash to cool
  2. Then collect them. Make sure to use safety glasses, gloves and face mask keep the ash from getting into your eyes, nose and mouth. You also may want to wear an apron or something that’s okay to get dirty.
  3. Apply the ash onto soil with low pH to increase the pH levels. The potassium and calcium carbonate helps balance out soil that’s too acidic to help plants absorb nutrients better.

Note that you should not use fireplace ash fertilizer on soil that’s already alkaline. Also, avoid application on plants that prefer acidic soil.

 

Coffee Ground Fertilizer Recipe

Got some used coffee grounds? Don’t throw them away and use them to create this DIY fertilizer instead.

Here’s how to do it.

Banana Peel Fertilizer

Banana Peel

If you enjoy eating bananas which my kids can’t seem to get enough of, putting the banana peels to good use helps save a few bucks each month.

One way you can use banana peels is to create a fertilizer with it.

Bananas are rich sources of vitamins and minerals. It is high in potassium, phosphorus and calcium, all of which are important ingredients in plan growth.

This lets you take advantage of the peel which would otherwise end up in the trash.

  • The best way to use banana peels is to plant them into the ground beside the plant. As the peels decompose, they will enrich the soil.
  • You can likewise create a spray. But, this will not make full use of the nutrients in the peels as you only get those that leeched out into the mixture.

 

Gelatin Fertilizer

Gelatin is another alternative to fertilizer. Although, I don’t like doing this because a pack of gelatin is something that’s new and consumable. Thus, it is not like the other ingredients on the list that are either scraps or to be thrown away.

In any case, if you’re looking to save money you can use this instead of fertilizer and see if it produces enough results to warrant its continued use.

  • Start by dissolving a pack of plain gelatin in a cup of hot water.
  • Then add 3 cups of cold water.
  • Once is has mixed, and cooled down to room temperature, you can pour it over soil. Avoid too hot or too cold water on soil.
  • You can use this fertilizer once a month.
