Homemade Fertilisers: Nourish Your Plants Naturally


When it comes to caring for our plants, organic and homemade fertilisers are an ideal solution to nourish our plants naturally, without compromising the health of the soil or the environment.

In this article, we will explore some simple and effective recipes for organic fertilisers that you can prepare at home to promote the healthy growth of your plants.

Why opt for organic fertilisers?

Organic fertilisers are those that are derived from natural and renewable sources, such as manure, compost, and food waste, among others. Unlike chemical fertilisers, organic fertilisers do not contain synthetic products or toxic substances that can harm soil, water or plant health in the long term.

In addition, organic fertilisers encourage microbial activity in the soil, which contributes to soil fertility and nutrient retention.

Homemade organic fertiliser recipes:

  • Liquid compost: Compost is an excellent organic fertiliser that you can make at home from food scraps and organic materials. To create liquid compost, simply soak mature compost in water for a few days, stirring occasionally. This resulting liquid will be loaded with beneficial nutrients for your plants and can be applied directly to the soil or diluted with water.
  • Manure tea: Manure is a rich source of nutrients that can enhance the growth of your plants. To make manure tea, place fresh manure in a permeable cloth bag and soak it in a container of water for several days. Then dilute the resulting liquid with water before applying it to your plants. This fertiliser is especially useful for vegetable crops and flowering plants.
  • Banana Peel Tea: Banana peels are an excellent source of potassium, an essential nutrient for plant growth and flowering. To make banana peel tea, simply cut the peels into pieces and steep them in water for several days. Then filter the liquid and use it to water your plants. This fertiliser is ideal for indoor and garden plants.
  • Nettle infusion: Nettles are a nutrient-rich plant that can strengthen the immune system of your plants and promote their growth. To make a nettle infusion, collect fresh nettle leaves and soak them in water for about a week. Then strain the liquid and dilute it with water before using it as a foliar fertiliser or to water your plants.
  • Rice water: Rice water is a simple organic fertiliser that can improve soil health and promote plant growth. After cooking rice, save the cooking water and let it stand until it is at room temperature. Then use it to water your plants. The starch and other nutrients in the rice water will help strengthen roots and improve soil structure.

Nitrogen-rich fertilisers

Nitrogen is an essential nutrient for the growth of your crops, especially during the vegetative phase, where plants are focused on developing their foliage and structure.

This element plays a crucial role in the production of chlorophyll, the green pigment responsible for photosynthesis, and in the formation of proteins, enzymes and nucleic acids that are essential for plant growth and development.

Fertiliser from rice, water and coffee grounds

An organic and natural way to provide nitrogen to your plants during the vegetative phase is by making a homemade fertiliser using common ingredients such as rice, water and coffee grounds.

To make this fertiliser, follow these simple steps:

  • Start with one cup of plain white rice. It doesn’t matter if it is brown or white rice, as both work well for this purpose.
  • Place the rice in a large bowl and cover it with water. Let the rice soak in the water for about 24 hours.
  • After the rice has been soaking, add a few tablespoons of used coffee grounds to the water. Coffee grounds are an excellent source of nitrogen and also contain other beneficial plant nutrients.
  • Stir the mixture to ensure that the rice and coffee grounds are evenly distributed in the water.
  • After 24 hours, filter the mixture to separate the liquid from the solids. You can apply it directly to the soil around your plants or dilute it with water according to the needs of your plants.

Nutritional needs of your plants

Understanding the nutritional needs of your plants during each phase of their growth is critical to providing proper plant care. Here are some general guidelines to help you identify what nutrients your plants might need at each stage:

Vegetative phase:

During the vegetative phase, plants are focused on developing their foliage and structure. At this stage, it is crucial to provide an adequate supply of nitrogen (N), which is essential for vigorous, green leaf growth.

If you notice that your plants have slow growth, yellowing leaves or pale green colour, it is likely that they need more nitrogen. You can apply nitrogen-rich fertilisers, such as manure tea or crushed eggshells, to meet these needs.

Flowering or fruiting phase:

During the flowering or fruiting phase, plants require a balanced supply of nutrients to support flower and fruit formation. In addition to nitrogen, it is important to provide phosphorus (P) and potassium (K), which are essential for the development of healthy flowers and fruits.

If you notice a lack of flowers or fruits on your plants, or if flowers drop prematurely, they may need more phosphorus and potassium. You can use fertilisers rich in these nutrients, such as banana peel tea or liquid compost, to stimulate flowering and fruiting.

Organic and homemade fertilisers offer a sustainable and environmentally friendly alternative to nourish our plants and promote healthy growth. By harnessing natural and renewable resources, we can grow thriving gardens and orchards without compromising the health of the soil or the environment.

In addition, preparing homemade fertilisers allows us to have greater control over the ingredients we use and reduce our ecological footprint in the process. Get excited to try these recipes at home and discover the benefits of fertilising your plants naturally!
