Fertilizers play a crucial role in gardening by providing essential nutrients that plants need to grow, thrive, and produce bountiful yields. While commercial fertilizers are widely available, they often come with a hefty price tag and potential environmental concerns. On the other hand, homemade fertilizers or composts offer a cost-effective, eco-friendly alternative tailored to your garden’s needs.
7 easy-to-make fertilizer/compost recipes
1. Compost tea
We begin our journey through garden-enhancing recipes with a standout favorite among eco-conscious gardeners: compost tea. This recipe marks the first step into a world where sustainability and effectiveness merge to support your garden in the most natural way possible. Ideal for both seasoned green thumbs and enthusiastic novices, compost tea introduces a method of nourishing plants that’s as kind to the environment as it is potent.
Compost tea is a nutrient-rich liquid fertilizer that enhances soil health and promotes robust plant growth. It contains beneficial microorganisms that help improve soil structure and nutrient availability.
To make compost tea, fill a large container with water and add a generous amount of compost. Let the mixture steep for 24-48 hours, stirring occasionally. Strain the liquid and dilute it with water at a 1:10 ratio before applying it to your plants. Use compost tea as a foliar spray or soil drench to boost your plants’ nutrients.
Some sources warn against compost tea because they are worried it could harbor dangerous bacteria like salmonella or E. coli, which reside in manure. This is why it is essential to use finished compost, not raw manure.
2. Banana peel fertilizer
Continuing our green journey through garden-enhancing concoctions, we now focus on a surprisingly simple yet potent homemade fertilizer made from banana peels. Often overlooked, those banana peels you’re about to throw away are packed with nutrients essential for healthy plant growth. Imagine converting your kitchen scraps into a goldmine for your garden, promoting sustainability and thriving plant life.
Banana peels are rich in potassium, an essential nutrient promoting flowering and fruit in plants. They also contain small amounts of phosphorus and calcium, which support root development and overall plant health.
To make banana peel fertilizer, chop the peels into small pieces and soak them in water for 24-48 hours. Strain the liquid and use it to water your plants. Alternatively, you can bury banana peels directly in the soil near the roots of your plants.
3. Eggshell fertilizer
As we explore natural, eco-friendly solutions for a thriving garden, our following recipe introduces a resource that is often underestimated, but readily available in most homes. Eggshells are not just a kitchen staple; they are a treasure trove of calcium and other essential minerals that can play a crucial role in the health and vitality of your plants. Eggshells are a natural source of calcium, which helps strengthen plant cell walls and prevents blossom end rot in tomatoes and peppers. They also contain trace amounts of other essential minerals.
Rinse and dry eggshells, then crush them into a fine powder using a mortar, pestle, or a blender. Sprinkle the crushed eggshells around the base of your plants or mix them into the soil. Add eggshells to your compost pile to enrich the compost with calcium.
4. Coffee grounds fertilizer
Coffee is the second most often traded commodity after cruise oil. Coffee grounds are an excellent nitrogen source, vital for leafy green growth. They also improve soil structure and attract beneficial earthworms. Collect used coffee grounds and let them dry. Sprinkle the coffee grounds around the base of your plants or mix them into the soil. You can also add coffee grounds to your compost pile to boost its nitrogen content.
Composting coffee grounds is possible if you don’t add so much that they comprise more than 20-35 percent of the compost pile material. Adding more coffee grounds as compost can prevent the whole lot from decomposing.
5. Epsom salt fertilizer
Epsom salt is not to be confused with regular kitchen salt. Its chemical compound is hydrated magnesium sulfate (about 10 percent magnesium and 13 percent sulfur).
Magnesium is vital for seed germination and producing chlorophyll, fruit, and nuts. It also helps strengthen cell walls and improves plants’ ability to absorb nitrogen, phosphorus, and sulfur. Epsom salt is composed of magnesium sulfate, which provides essential magnesium and sulfur to plants. Magnesium is crucial for photosynthesis, while sulfur aids in producing amino acids and enzymes.
Dissolve one tablespoon of Epsom salt in a gallon of water. Water your plants once a month with the solution. You can also sprinkle Epsom salt directly around the base of your plants and water it in.
6. Fish emulsion fertilizer
When venturing into organic gardening, fish emulsion fertilizer is a remarkable choice for those seeking to nourish their plants naturally. With just two essential ingredients, this homemade fertilizer unlocks an array of benefits for both plants and soil. It’s a high-nitrogen elixir that turbocharges plant growth and enriches the soil with trace minerals and a community of beneficial microorganisms.
The magic begins with the fermentation of fish scraps in water, a process that might test your patience over several weeks, but promises to transform your gardening experience. To make a fish emulsion, blend fish scraps with water and let the mixture ferment for several weeks. Strain the liquid and dilute it with water at a 1:10 ratio before applying it to your plants. Use fish emulsion as a soil drench or foliar spray.
Fish emulsion is a high-nitrogen fertilizer that promotes vigorous plant growth. It also contains trace minerals and beneficial microorganisms that enhance soil health.
7. Grass clippings fertilizer
Are you looking to boost your garden without spending a fortune on expensive fertilizers? You might find the answer lying in the aftermath of your lawn-mowing efforts. This approach is cost-effective and a fantastic way to recycle and reduce waste. In this guide, we’ll discuss the simple ingredients you need (hint: it’s just your fresh grass clippings), explore their benefits to your garden, and walk you through how to apply them to get the best results.
Grass clippings are rich in nitrogen and decompose quickly, making them an excellent source of nutrients for your garden. They also help retain soil moisture and suppress weeds when used as mulch. Spread a thin layer of fresh grass clippings around the base of your plants, being careful not to smother them. You can also add grass clippings to your compost pile to increase its nitrogen content.
The benefits of homemade fertilizer
Using homemade fertilizers offers several environmental and economic benefits. Recycling kitchen scraps and yard waste reduces the amount of organic material in landfills, decreasing greenhouse gas emissions.
Homemade fertilizers are also free from synthetic chemicals, making them safer for the environment and beneficial insects like bees and earthworms. Additionally, making your fertilizers can save you money compared to purchasing commercial products.
