Did you know you can make fertilizer with things you have around your house? It’s true! Here are some easy ways to feed your plants with household items you probably already have.
Coffee grounds are rich in nitrogen, plus they add organic matter to the soil, aerate it, and help with water retention. After brewing your coffee, simply add a few spoonfuls of grounds directly to the top of the soil around your plant. (Don’t use grounds that haven’t already been brewed – these are too acidic and can hurt your plants).
Eggshells are packed with calcium, which is essential for plants. You can simply crush your shells over your soil, or you can pulverize them into an easy-to-apply, easy-to-absorb powder. To do this, boil your eggshells for 5 minutes, then bake them in the oven at 350 F (176 C) for 15 minutes. Next, grind them into a fine powder in a food processor. Sprinkle the powder directly onto your plants’ soil, and water immediately after.
Roughly chop your banana peel, then soak it in water for at least five hours. Strain this mixture through a sieve and use the nutrient-packed liquid you get to water your plants.
You’re not as likely to have this one, but you might! Epsom salt helps plants grow greener and bushier, and helps them take up nutrients. Simply mix 1-2 tablespoons (15-30 mL) into 1 gallon (3.7 L) of water, and use it to water your plants.
