4 DIY Fertiliser Ideas You Can Do at Home – Our Guide

When you grow plants on soil, you would generally enhance the growth with some fertiliser. From plant nutrient enhancers to even hydroponic moonshines (while designed for hydroponic use, can be used in any growing program), these all help benefit your plants by making them grow not only faster but stronger too. If you wanted your plants to have more yield and maintain their health, you can also use bio-stimulants.

However, these fertilisers and stimulants can sometimes get a little too expensive for your liking. While they serve their purpose, it is also a great idea to supplement the use of these pre-made items with your own home-made fertilisers.

With that said, here are four ways you can make your own fertilisers.

1. Coffee Grounds

You love coffee, don’t you? No? Well, if you do not have any coffee grounds with you, you can pick up some at your local coffee shop. If you do have some grounds from your daily ritual, it is time to put them to good use. 

Coffee contains nitrogen, magnesium, copper, potassium, and phosphorous, all of which are present in fertilisers. That means that coffee grounds make excellent natural fertilisers. You can either compost them first or mix them directly into the soil. In a sense, you’re making the most bang out of your buck, using coffee for drinking, and the grounds to grow your garden.

2. Eggshells

Eggshells make excellent fertilisers as well. While eggshells contain compounds, such as nitrogen and phosphorous, what makes it excellent is the calcium. 

Calcium helps in many ways. For example, the calcium can help strengthen cell walls, helping the plant keep its shape and look healthy. To feed this calcium to your plants, grind down the shells to small bits, and either mix them to the compost or add it to the soil.

3. Aquarium Water

Do you have a fish tank with you? Then, the chances are that you have cleaned it out occasionally, and that includes throwing away the water. This dirty water, filled with fish manure, contains potassium, nitrogen, and phosphorus.

The next time you decide to pour out the water to clean the tank, pour it gently into the soil for your plants to enjoy. However, do not do this if you’ve treated the water with some antibiotics or other chemicals. These substances will kill off the good bacteria in the soil, which is not ideal for plant growth.

4. Fireplace Ash

If you have a fireplace, the ash that’s collected inside contains some potassium, as well as calcium. While you can add the ash directly to the soil, you can also turn it into a form of liquid. 

To make liquid fertiliser, fill some linen bag (or an old pillowcase) with ash and tie it tightly. Find a large barrel, fill it with water, and place this bag into the water. After a week, you’ll have water filled with nutrients for your plants to enjoy.

In conclusion, by utilizing bought fertilisers and stimulants along with home-made ones, you can enjoy healthy plants at a minimal cost. At the same time, you’re reducing the overall waste produced. By turning items that are generally discarded into food for your plants, you reduce the amount of waste you make and make the most with what you have—an excellent benefit, especially for those trying to become more environmentally friendly.
