10 ways to feed your garden without spending a dime (Page 2 ) | June 28, 2025

Banana peels are rich in potassium, an essential nutrient that helps plants with water uptake, enzyme activation, and overall growth. Instead of throwing away banana peels, use them to feed your garden.
There are several ways to use banana peels in your garden. You can chop them up and bury them directly in the soil near the roots of your plants, or you can dry them and grind them into a powder to sprinkle around your garden. Alternatively, you can make a banana peel tea by soaking the peels in water for a few days and then using the liquid to water your plants.
5. Wood Ash for Alkaline Soil
Wood ash from a fireplace or wood stove can be a valuable addition to your garden, especially if you have acidic soil. Wood ash contains potassium and calcium carbonate, which can help raise the pH level of the soil, making it more alkaline.
To use wood ash in your garden, first ensure that it is completely cool and free of any charcoal or chemical residues. Sprinkle the ash lightly over your garden beds and mix it into the soil. Be cautious not to overapply, as too much ash can raise the pH too high and harm your plants. A general guideline is to use about 5 pounds of wood ash per 100 square feet of garden space.
6. Epsom Salt for Magnesium Deficiency
Epsom salt, or magnesium sulfate, is a natural mineral compound that can help correct magnesium deficiencies in plants. Magnesium is crucial for photosynthesis and helps plants absorb other nutrients more effectively.
To use Epsom salt in your garden, dissolve 1 tablespoon of Epsom salt in a gallon of water and use it to water your plants once a month. You can also sprinkle the salt directly around the base of your plants and water it in. This treatment is particularly beneficial for tomatoes, peppers, and roses, which are often prone to magnesium deficiencies.
7. Grass Clippings as a Nitrogen-Rich Mulch
Grass clippings are an excellent source of nitrogen and can be used as a mulch to feed your garden. By spreading a layer of grass clippings around your plants, you can help retain soil moisture, suppress weeds, and provide a slow-release source of nitrogen as the clippings decompose.
To use grass clippings as mulch, spread a 1- to 2-inch layer around your plants, being careful not to pile them too thickly, as this can lead to matting and mold. Avoid using clippings from lawns that have been treated with herbicides or pesticides, as these chemicals can harm your plants.
