Every gardener’s dream is a thriving raised bed garden filled with lush, healthy vegetables. One essential ingredient for achieving this is nutrient-rich soil, and homemade liquid fertilizers can provide an easy, cost-effective way to enrich the soil in your raised beds.
These fertilizers are more sustainable than their store-bought counterparts and allow you to upcycle kitchen waste and reduce your environmental impact. In this article, we’ll explore the best DIY liquid fertilizers for raised bed plants, focusing on creating and applying these liquid fertilizers to achieve the greatest results.
Best Homemade Liquid Fertilizer for Raised Bed Plants
Compost Tea
Compost tea, a common DIY fertilizer created by steeping compost in water, absorbs the compost’s nutrients and benefits for the plant. A concentrated supply of nutrients can be sprayed directly into the soil in a raised bed to encourage root development and general plant health.
Place a shovel of finished compost in a burlap sack or an old pillowcase to create compost tea. Tie the sack closed and immerse it in a large bucket or barrel filled with water. Allow the mixture to steep for 5-7 days, stirring occasionally. Before putting compost tea into plant soil, dilute it 1:10 with water.
Kitchen Waste Fertilizer
Using kitchen waste to create homemade fertilizer is an excellent way to recycle and repurpose household waste while providing your raised bed plants with essential nutrients. Kitchen waste fertilizer can be made from a variety of sources, including fruit and vegetable scraps, coffee grounds, and eggshells.
To make this fertilizer, collect your kitchen waste in a large container. Once you have enough waste, blend it with water to create a slurry. The ideal ratio is one part kitchen waste to two parts water. Strain the mixture to remove large particles and apply the liquid directly to the soil around your plants. This nutrient-rich fertilizer is particularly beneficial for vegetables in raised beds, as it provides a steady supply of organic matter and helps to improve soil structure.
Fish Emulsion Fertilizer
Fish emulsion is a potent homemade liquid fertilizer made from fish waste, such as scraps, bones, and innards. Its high nitrogen, phosphate, and potassium concentrations make it an excellent option for fertilizing the plants in your raised bed garden. Fish emulsion is made by placing fish scraps in a big container and filling the container with water.
The breakdown process can be sped up and odours muted by adding a tiny quantity of unsulphured molasses to the mixture. Allow the mixture to ferment for 2-4 weeks, stirring occasionally to ensure even decomposition. Once the fish emulsion is ready, strain the liquid and dilute it with water at a 1:5 ratio (one part fish emulsion to five parts water) before applying it to the soil around your plants.
Seaweed Extract Fertilizer
Seaweed extract is another nutrient-dense homemade fertilizer that can be particularly beneficial for raised bed plants. Rich in trace minerals and growth hormones, seaweed extract promotes strong root development, increased plant growth, and improved resistance to pests and diseases. To make seaweed extract, gather fresh or dried seaweed and rinse it thoroughly to remove any salt. Place the seaweed in a large container and cover it with water. Allow the mixture to steep for 3-4 weeks, stirring occasionally.

Once the seaweed extract is ready, strain the liquid and dilute it with water at a 1:5 ratio (one part seaweed extract to five parts water) before applying it to your raised bed plants. Regular application of seaweed extract can significantly improve the health and productivity of your plants, making it an excellent addition to your homemade fertilizer arsenal.
Banana Peel Fertilizer
Potassium, an important element for plant health that stimulates blossom and fruit growth, can be found in plenty of banana peels. A DIY liquid fertilizer made from banana peels can provide a potassium boost to your raised bed plants, helping them grow larger and healthier. To make banana peel fertilizer, collect banana peels in a large jar or container. Cover the peels with water and allow the mixture to steep for 2-3 days. After steeping, strain the liquid and use it to water your plants. The leftover peels can be added to your compost pile or directly buried in the soil to decompose and release additional nutrients.
Manure Tea
Manure tea is another homemade liquid fertilizer option that can provide a substantial nutrient boost to your raised bed plants. Manure from chickens, rabbits, cows, or horses is rich in nitrogen, phosphorus, and potassium, making it an excellent choice for a DIY fertilizer. Place a shovelful of well-rotted manure in a burlap sack or pillowcase and tie it shut to make manure tea. For a week or two, immerse the bag in a large container of water, stirring occasionally. After steeping, strain the liquid and dilute it at a 1:10 ratio (one part manure tea to ten parts water) before applying it to your raised bed plants.
Epsom Salt Fertilizer
Epsom salt is a common household item used to make a quick and easy homemade liquid fertilizer. It is high in magnesium and sulfate, which are vital for plant health. Chlorophyll, which is required for photosynthesis, contains magnesium, and sulfate helps in protein synthesis. To make fertiliser, mix one tablespoon of Epsom salt with one gallon of water. The soil in your raised beds may benefit immediately from this treatment. It is particularly beneficial for vegetables like tomatoes and peppers, which require high magnesium.
Coffee Grounds Fertilizer
Coffee grounds are rich in nitrogen, an essential nutrient for plant growth. They can be included in a quick and easy homemade liquid fertilizer for your plants in a raised bed. Used coffee grounds can be recycled into fertilizer by combining them with a pail of water. The ideal ratio is 6 cups of coffee grounds to 5 gallons of water. Let the mixture steep for 2-3 days, stirring occasionally. After steeping, strain the liquid and use it to water your plants. The leftover coffee grounds can be added to your compost pile or used as a soil amendment.
