Preparing Your Materials

Before you start composting, gather the necessary materials to create your homemade compost fertilizer. You will need the following items:

  1. Compost bin or container: Choose a container or bin specifically designed for composting. There are various options available, including compost bins made of plastic, metal, or wood. Make sure the bin has good ventilation and drainage.

  2. Organic waste: Collect different types of organic waste in your kitchen and garden. Kitchen scraps like fruit and vegetable peels, coffee grounds, tea bags, and eggshells are excellent sources of nutrients for your compost. From the garden, include dry leaves, grass clippings, and small trimmings.

  3. Brown materials: Brown materials, also known as carbon-rich materials, help balance the compost. Collect items like dried leaves, shredded paper, straw, and small twigs.

  4. Water: Water is essential for composting. Ensure you have a convenient water source nearby to keep the compost moist. Using a watering can or a garden hose with a gentle spray nozzle can make the task easier.

Building the Compost Pile

Now that you have gathered all your materials, it’s time to build your compost pile. Follow these steps:

  1. Layer the compost bin: Begin by layering the compostable materials in your chosen bin. Start with a layer of brown materials, followed by a layer of organic waste. Repeat this alternation until you have used up all your materials. Aim for a balanced ratio of approximately three parts brown materials to one part green or organic waste.

  2. Moisture management: It’s essential to keep your compost pile moist, similar to a damp sponge. Water the pile as you layer the materials to ensure proper moisture content. Monitor the moisture level regularly, and adjust by adding water if the pile feels dry or by adding more brown materials if it becomes too wet.

  3. Turning the pile: To promote decomposition and provide oxygen to the microorganisms responsible for breaking down the materials, turn the compost pile regularly. Use a garden fork or a compost aerator to gently mix the outer materials into the center. Aim to turn the pile once every one to two weeks.

  4. Patience and decomposition: Composting is a natural process that takes time. The length of time required for your compost to fully decompose depends on various factors such as temperature, moisture, and the size of your compost pile. In general, composting can take several weeks to several months. As time passes, you will notice a dark, crumbly, and earthy-smelling material forming.

  5. Harvesting the compost: Once the compost materials have broken down into a rich, dark, and crumbly soil-like consistency, your compost is ready to be used as fertilizer for your houseplants. Harvest the compost by scooping it out from the bottom of the compost bin or container.

Applying Compost to Houseplants

Now that you have your homemade compost fertilizer, it’s time to apply it to your houseplants. Here’s how:

  1. Preparation: Before applying the compost, ensure your houseplants are in need of fertilization. Signs that your plants may need a nutrient boost include slow growth, yellowing leaves, or a lack of flowers. Inspect the soil moisture levels and adjust as necessary before applying the compost.

  2. Surface application: Spread a thin layer of compost around the base of your houseplants, extending it slightly beyond the drip line (the imaginary line formed by the outermost branches). Be careful not to pile the compost against the plant stems or foliage, as this can promote rot and disease.

  3. Mixing with potting soil: If you are repotting or transplanting houseplants, mix the compost thoroughly with the potting soil. Use a ratio of approximately 1 part compost to 3 parts potting soil to ensure a balanced nutrient supply for your plants.

  4. Watering: After applying the compost, water your houseplants thoroughly to help the compost integrate into the soil. This ensures that the nutrients are available to the plant roots.

Benefits of Homemade Compost Fertilizer for Houseplants

Creating your own compost fertilizer for houseplants offers several benefits:

  1. Sustainable and cost-effective: Composting allows you to recycle organic waste and reduce your environmental footprint. By making your own compost fertilizer, you save money on commercial fertilizers and reduce the use of synthetic chemicals.

  2. Improved soil health: Homemade compost provides a rich source of organic matter, improving soil structure, water retention, and nutrient availability. It enhances the overall health and fertility of your houseplant’s growing medium.

  3. Nutrient-rich supply: Compost is a slow-release fertilizer, releasing nutrients gradually over time. It provides a balanced mix of essential plant nutrients, including nitrogen, phosphorus, and potassium, as well as trace elements needed for optimal plant growth.

  4. Disease prevention and plant resilience: Compost contains beneficial microorganisms that help suppress harmful pathogens and pests in the soil. This can lead to healthier houseplants with increased resistance to diseases and improved overall resilience.


Creating your compost fertilizer for houseplants is a rewarding and eco-friendly DIY project. By recycling organic waste and turning it into nutrient-rich compost, you provide your houseplants with a sustainable source of nourishment. The steps are simple: gather your materials, build the compost pile, wait for decomposition, and apply the compost to your houseplants. Enjoy the benefits of improved soil health, cost savings, and the satisfaction of contributing to a greener planet. Start composting today and watch your houseplants thrive!
