The potted plants They need nutrients to thrive, just like those grown in soil. While you can find a variety of commercial fertilizersMany are expensive and unsustainable. Making your own homemade compost is not only simple and inexpensive, but also an excellent way to feed your plants, reduce waste, and contribute to the environment. Below, we'll show you how. How to make homemade compost for potted plants with simple and effective methods, integrating expert advice and making the most of domestic resources.
Reasons to Make Homemade Fertilizer for Potted Plants
- Extra nutrient intake: Homemade fertilizer provides your plants with the key elements they need to thrive: nitrogen, phosphorus, potassium, and essential micronutrients like calcium, iron, and magnesium. You can also find more information at natural and homemade fertilizers.
- Sustainability and waste reduction: By recycling kitchen and garden scraps, you reduce the amount of trash and avoid the pollution caused by chemical fertilizers.
- Economic savings: Making homemade compost is practically free and helps you use resources that would otherwise end up in the trash.
- Avoid unnecessary chemicals: Using natural fertilizer preserves the balance of the soil and the health of your plants, encouraging the arrival of beneficial insects.
If you don't usually fertilize your plants, now's the time to start. Fertilizer improves the texture of the substrate, increases fertility, and revitalizes its nutritional value. This is vital in pots, where space and natural resources are limited.
What Do You Need to Make Homemade Plant Fertilizer?
- Fruit and vegetable peels: Rich in nitrogen, but also providing potassium and magnesium. Chop the shells into small pieces to facilitate their decomposition. You can learn more about their use at homemade fertilizers with fruit peels.
- Coffee grounds and tea bags: Coffee grounds provide nitrogen, phosphorus, and potassium, as well as iron. They are ideal for plants that prefer more acidic soils. Tea bags also provide nitrogen and help aerate the substrate.
- Crushed eggshells: A natural source of calcium, essential for strengthening roots and preventing disease. They also help raise soil pH.
- Garden waste: Include dry leaves, grass clippings (rich in nitrogen), and small branches (which provide carbon). These ingredients balance the green and dry matter for efficient compost.
- Tea bags and leftover infusions: They add nitrogen and light organic matter to the compost.
- Special waste: Potato peels, banana and onion skins, rice grains, wood ashes, non-alcoholic beer, and lentils are highly recommended for their richness in potassium, phosphorus, iron, and other micronutrients.
To get started, you just need a container to store and mix these materials, and a little patience to let the organic matter decompose into the ideal fertilizer for your plants.
Types of Homemade Fertilizers for Potted Plants
- Organic compostThis is the classic method. Use a compost bin or a bucket with holes to allow kitchen and garden scraps to decompose slowly. Mix in dry leaves, fruit and vegetable scraps, eggshells, and small branches. Stir the mixture every two weeks to aerate it and speed up the process. In two to four months, you'll have mature compost ready for your plants.
- compost tea: It's prepared by soaking organic material in water for several days (you can use a cloth bag). The resulting water is used to water plants, adding nutrients quickly and effectively. For more ideas on its uses, visit how to make homemade foliar fertilizer.
- Vermicompost or worm humus: It involves using red worms to break down waste and create rich, loose compost full of beneficial microorganisms. Simply place the worms and scraps in a suitable container and let them do the work.
- Homemade liquid fertilizersIdeal for quick nutrition. These include "banana tea" (water with banana peel) and "nettle infusion." Both provide essential nutrients such as potassium and iron.
Depending on the time, space, and variety of waste you generate, you can choose one or a combination of these methods.
Homemade Liquid Fertilizers: Recipes and Tips
- Banana tea: Place the peels in water for 24-48 hours. Water the pots with this liquid, which is ideal for stimulating flowering.
- Nettle infusion: Fill a bucket with fresh nettles and water. Let it sit for two weeks, stirring occasionally. Use it for watering, especially young or newly transplanted plants, due to its iron, magnesium, and nitrogen content.
- Alcohol-free beer: Add small diluted amounts to increase nitrogen in the substrate.
- Lentil water: Soaking lentils in water releases phytic acid, which stimulates root growth. Use the soaking water to water your plants, especially after transplanting.
These liquid fertilizers act quickly and are an excellent complement to solid compost. Rotate their use according to your plants' seasonal needs and the type of crop you grow.
Household Ingredients That Fertilize Your Plants
- Coffee grounds: They improve drainage and water retention in the substrate. They provide nitrogen and phosphorus, and help acidify the soil. For other resources on the topic, visit list of organic fertilizers.
- Rice grains: Source of potassium, phosphorus, iron, and magnesium. Especially useful for indoor and potted plants.
- Eggshells: Ideal for plants that do not tolerate acidity well. They provide calcium and slightly raise the soil pH.
- Potato peels: High in potassium and phosphorus, excellent for stimulating growth.
- Onion skins: In addition to potassium and magnesium, they have antimicrobial and antifungal effects.
- Vegetable ashes: Rich in minerals, only suitable for plants that tolerate alkaline soils.
- Cigarette butts (optional): Rich in nitrogen, phosphorus, and potassium. Use with caution and in very small quantities.
Remember not to overdo the amount applied, especially in small spaces like pots, to avoid the risk of salt and nutrient saturation.
What Type of Fertilizer Does Each Plant Need?
- Flowering plants: They require a greater amount of potassium (banana peels, onions, potato peels and rice) to promote flowering and fruit development.
- Green leafy plants: They prefer nitrogen-rich fertilizers, which promote leaf growth. Coffee grounds, grass clippings, and nettles are perfect for this.
- Acidophilic plants (azaleas, camellias, gardenias): Especially beneficial are coffee grounds and finely crushed eggshells (in moderate quantities).
- Mediterranean Aromatics: They require fertilizers with low acidity content and, if necessary, some calcium (eggshells).
It's important to observe your plants' responses to fertilizer. Too much can cause problems such as leaf burn or salt saturation, while a lack of nutrients limits growth and flowering. Adapt the composition and frequency of fertilizer to each species and the life cycle of the crop.
How to Make Homemade Fertilizer for Potted Plants Step by Step
- Gather the materials: Collect household organic waste and garden waste.
- Cut into small pieces: It facilitates decomposition and prevents bad odors.
- Combine green and dry matter: For a balanced compost without excess moisture.
- Use a ventilated container: You can use a compost bin, perforated bucket or wooden box.
- Stir regularly: Aerating the mix is key to avoiding compaction and speeding up the process.
- Wait the right amount of time: Two to four months for solid compost; a few days or weeks for liquid fertilizers.
- Filter and apply: The mature compost is incorporated into the potting soil. Liquid compost can be used for irrigation, diluted with water if necessary.
Make sure not to add meats, dairy products, oils, or cooked leftovers to avoid attracting pests and creating unpleasant odors.
Making homemade compost for potted plants allows you to use everyday materials, boost your plants' well-being, and promote a healthier environment. Combine techniques and adjust recipes according to your crops' needs to always achieve the best results, respecting the natural rhythm of composting and avoiding overfeeding.
