8 DIY Organic Fertilizers: Boosting Your Garden the Natural Way

There is nothing more satisfying than getting your hands dirty and helping your garden thrive, especially when you know you’re doing right by the environment.

For soil and plant health, there really is nothing better than the organic route. While there will always be companies trying to cash in on the environmentally conscious, there are many effective fertilizers you can make yourself.

With a little effort, you can encourage your garden to bloom to its full potential using everyday kitchen scraps and garden waste, so let’s explore.

Why Go Organic? Exploring The Benefits 

Let’s take a quick look at why gardeners are going organic before we discuss how you can easily make the leap yourself.

Healthy Soil Means Healthy Plants

Shop-bought synthetic fertilizers deposit nutrients into the soil, but they don’t feed the soil and enrich it like an organic fertilizer.

By feeding the soil, you help support microbial life in the soil ecosystem. The organic matter forces plants to develop stronger root systems and improves water retention, offering protection against drought. 

The nutrients are slow-released and last longer, which helps promote more vibrant growth.

Environmentally Friendly

When you make your own organic fertilizers at home, you reduce your waste, which in turn lowers your carbon footprint. 

You also lower the amount of harmful chemicals being used that make it into our waterways and destroy ecosystems.

Homemade Organic Fertilizer Ideas

Now it is time to take a look at some effective DIY fertilizers that can be made at home from scraps.

These eight homemade fertilizers are low-cost, easy to make, and will help boost your garden’s productivity without introducing chemicals.

1. Banana Peel Infusion

Potassium and phosphorus help plants to flower and fruit, and banana peel contains both in abundance. 

Chopping a few peels into pieces and soaking them in water for 2–3 days creates a nutrient-rich liquid that can be added to your watering routine.

Alternatively, you can bury a banana peel directly in the soil nearby.

2. Ground Eggshells

Calcium is great for preventing blossom end rot, which is a common problem in nightshades such as tomatoes and peppers. 

By grinding your eggshells with a blender or by hand with a pestle and mortar, you get a fine powder to add to your potting mix. You can also sprinkle on top of established gardens.

3. Old Coffee Grounds

Nitrogen is one of the three key nutrients found in fertilizer. It is slow-release, great for attracting earthworms, and helps improve the texture of the soil.

Used coffee grounds are a surefire way to add some nitrogen, but too much nitrogen can change the pH of the soil, making it acidic. So, exercise caution and add it to your compost heap or mulch.

4. Fresh Grass Clippings

Another nitrogen-rich waste product that can be added to your mulch is grass clippings from your yard. Just be sure they are free of chemical treatments. 

Adding them to the surface of your beds around plants also helps suppress weeds.

5. Homemade Compost Tea

Compost tea is the nutrient-rich liquid created by steeping and straining homemade compost in water.

In studies, this nutrient-packed liquid increased yields by 92% more than the other controlled treatments studied.

6. Dirty Fish Tank Water

We all know manure is great for fertilizing. While you might not have a horse of your own to make use of, if you are a freshwater fish owner, then you have access to natural fertilizer. 

This nutrient-rich water is excellent for garden plants

7. Ashes

The ashes of burned untreated wood can provide both potassium and calcium carbonate to your garden, but you must be sure not to overdo it.

Never sprinkle it around acidic-loving plants because it lowers the pH levels.

8. Soaking Seaweed

There are also some great minerals to be found in seaweed. It must be rinsed thoroughly because of the salt content of the sea. Once rinsed, you can soak it in water for a few days.

The resulting liquid can help boost plant immunity and growth. Dried seaweed products can also be used if you are nowhere near the coast.

DIY Organic Fertilizer Tips

Now you know what to use, you need to know how to use it to avoid any harmful imbalances.

So, here are a few tips to help with implementation, application, and furthering your knowledge.

1. Gradual Introduction

Garden soil needs to be well-balanced, and introducing DIY fertilizers can be tricky to navigate early on. The best advice is to start with a small test area and monitor the way that the plants respond.

2. Try to Compost First

Generally speaking, you want to introduce the waste scraps in a composted state. Let them decompose before adding them to your soil; that way, they will be nutrient-dense.

3. Learn to Mix-n-Match

Plants have different needs; leafy greens love nitrogen, and tomatoes prefer calcium. So it is important to learn a little and strike the right balance for each type of plant you want to grow.

Learning to mix and match your DIY fertilizers accordingly is an invaluable skill.

Gardening forums and online groups, and communities are a great source for expanding your knowledge and getting the mix just right.

There are also tons of how-to videos to watch and learn from.
