Top 7 DIY Organic Fertilizer Recipes

Mixing up your DIY organic fertilizer recipes is like cooking a wholesome meal for your plants. Using homemade products like kitchen scraps or yard clippings, you can whip up nutrient-packed recipes for your plants that make your garden thrive without relying on chemical products. 

This guide spills the beans on seven super-simple, zero-waste fertilizing methods that tap into composting kitchen scraps and other natural plant nutrients. But before we get into the recipes, let’s learn about why we need to go DIY with organic fertilizers; 

Why Go DIY with Organic Fertilizers?

Organic fertilizers are like a warm hug for your soil, delivering essential nutrients such as nitrogen, phosphorus, potassium, etc. They serve as an excellent alternative to synthetic products causing potential harm to your plants. DIY fertilizers are not only gentle on the soil but are fully biodegradable, and won’t cost you a fortune. 

Additionally, they allow you to turn things like vegetable peels or grass clippings into garden gold, cutting down on waste. By diving into these zero-waste fertilizing methods, you’re not just feeding your plants; you’re giving a little love back to the environment.

Ready to get your hands dirty? Here are seven recipes to try.

#1 Compost Tea: The Garden’s Favorite Brew

Perfect for: All-around plant health, boosting soil life
What you’ll need:

  • A gallon of water (rainwater is best, but tap water left out overnight works as well).

  • A couple cups of rich compost (think vegetable scraps, coffee grounds, eggshells from composting kitchen scraps).

  • A spoonful of unsulfured molasses (optional, to make microbes happy).

How to make it:

  1. Stuff your compost into an old pillowcase or a breathable sack.

  2. Dunk it in a bucket of water and let it steep for a day or two, giving it a stir now and then.

  3. Toss in the molasses; it’s like a treat for the good bacteria.

  4. Strain the liquid, dilute it with water (1 part tea to 10 parts water), and pour it around your plants or spritz it on their leaves.

Why it works? Compost tea is like a nutrient smoothie, packed with natural plant nutrients that wake up your soil’s microbes. It’s great for everything from tomatoes to petunias.

Pro tip: Use it fresh. Consider it like a cup of coffee that loses its zing if it sits too long.

Perfect for: This DIY recipe is ideal for flowering or fruiting plants such as roses and tomatoes.
What you’ll need:

  • 3-4 banana peels (straight from your breakfast, part of composting kitchen scraps).

  • A gallon of water.

How to make it:

  1. Chop those peels into bite-sized bits.

  2. Toss them in a jug of water and let them soak for a couple of days.

  3. Strain out the liquid and pour it around your plants’ roots.

  4. Don’t toss the soggy peels; add them to your compost for true zero-waste fertilizing methods.

Why it rocks: Banana peels are a powerhouse of potassium, giving your plants the boost they need for big, beautiful blooms and juicy fruits.

Pro tip: Got extra peels? Dry them out, crush them up, and sprinkle them into the soil for a slow-release nutrient mechanism.

#3 Eggshell Dust: Calcium to the Rescue

Perfect for: Saving tomatoes and peppers from blossom-end rot.
What you’ll need:

  • A dozen eggshells (from your morning omelets, part of composting kitchen scraps).

  • A splash of water for rinsing. 

How to make it:

  1. Rinse the eggshells to get rid of any eggy bits.

  3. Grind them into a fine powder with a mortar and pestle or a blender.

  4. Sprinkle the dust around your plants or mix it into the soil.

Why it rocks: Eggshells are loaded with calcium, which strengthens plant cell walls and keeps diseases at bay. It’s a classic zero-waste fertilizing method and one of the most effective DIY organic fertilizer recipes.

Pro tip: Keep the powder in a jar for whenever your plants need a calcium pick-me-up.

#4 Coffee Ground Mulch: A Nitrogen Nudge

  • Optional: Some dried leaves or grass clippings.

How to make it:

  1. Collect your coffee grounds and let them air-dry to avoid mold.

  2. Spread a thin layer (about half an inch) around your plants’ bases.

  3. Mix in some leaves or clippings to keep the soil airy.

  4. Top it up every few weeks for steady nutrients.

Why it rocks: Coffee grounds are a nitrogen goldmine, perfect for lush, leafy growth. They also make your soil a cozy home for earthworms.

How to make it:

  1. Fill a bucket halfway with grass clippings.

  2. Pour in water and let it sit for 3-5 days, stirring it daily like a witch’s brew.

  3. Strain the liquid and dilute it (1 part tea to 5 parts water).

  4. Pour it over your plants or lawn.

Why it rocks: Grass clippings are bursting with nitrogen, giving your greens a serious growth spurt. It’s a great way to recycle yard waste.

Pro tip: Double-check that your clippings are free of weed killers or pesticides.

#6 Wood Ash Sprinkle: A Potassium Punch

Perfect for: Root veggies like carrots or beets, or acidic soils
What you’ll need:

  • Wood ash (from a fireplace, as long as it’s untreated wood).

  • Water (optional, for a liquid version).

How to make it:

  1. Gather cooled ash and sift out any big chunks.

  2. Dust a light layer (a tablespoon per square foot) around your plants.

  3. For a liquid feed, mix 1 cup of ash with a gallon of water, let it sit for a day, and water your plants.

  4. Give the soil a good drink afterward to lock in the ash.

Why it rocks: Wood ash brings potassium and calcium to the table, plus it helps balance acidic soils. It’s a zero-waste fertilizing method for fireplace fans.

Pro tip: Check your soil’s pH first; too much ash can tip the scales too alkaline.

#7 Veggie Scrap Broth: A Nutrient Stew

Perfect for: Potted plants or small gardens
What you’ll need:

  • A gallon of water.

How to make it:

  1. Rinse your scraps to clean off any dirt.

  2. Boil them in water for about half an hour to pull out the good stuff.

Why it rocks: This broth is like a multivitamin for your plants, delivering natural plant nutrients in a form they soak right up.

Pro tip: Toss the boiled scraps into your compost to keep the zero-waste fertilizing method going.
