Coffee Grounds and Eggshells: The Breakfast of Champions for Your Lawn

It turns out that coffee grounds and eggshells aren’t just great for composting; they’re also fantastic for feeding your lawn! Rich in nitrogen, potassium, and calcium, these kitchen scraps are essential nutrients that promote healthy growth in your grass.

Recipe

Ingredients:

  • 4 cups of used coffee grounds,
  • 12 crushed eggshells,
  • 1 gallon of water.

Instructions:

  1. Begin by collecting used coffee grounds and rinsed, crushed eggshells in separate containers. You can store them in the fridge or freezer to prevent mold growth until you’re ready to use them.
  2. Once you have enough kitchen scraps, mix the coffee grounds and crushed eggshells together in a large bucket or container.
  3. Add one gallon of water to the mixture and stir well to ensure even distribution of the ingredients.
  4. Allow the mixture to sit for at least 24 hours, stirring occasionally. This will help release the nutrients from the coffee grounds and eggshells into the water.
  5. Using a garden watering can with a sprinkle head or a hose-end sprayer, evenly distribute the liquid fertilizer across your lawn. Focus on any thin or patchy areas that need an extra boost.
  6. Water your lawn thoroughly after applying the homemade fertilizer to help the nutrients seep into the soil (Quick note: this step applies to each and every fertilizer recipe).

Extra Tips:

  • For best results, apply this coffee ground and eggshell fertilizer once a month during the growing season (spring and summer).
  • Be sure to crush the eggshells well, as large pieces can take longer to break down and may not provide the same level of nutrients as smaller particles.
  • If you’re worried about potential pests being attracted to the coffee grounds or eggshells, you can bury the mixture a few inches deep in your lawn instead of sprinkling it on top. This will still provide the necessary nutrients while keeping critters at bay.

Not only will this recipe give your grass a much-needed boost, but it’s also an excellent way to recycle those pesky kitchen scraps. So, go ahead, indulge in that extra cup of coffee, or whip up a delicious omelet — your lawn will thank you!

Beer Brew-tality: A Boozy Boost for Your Grass

Could it be true? Is beer actually good for your lawn? Surprisingly enough, yes!

Beer contains yeast, which breaks down dead organic matter like grass clippings and fallen leaves, turning them into valuable nutrients for your yard. When combined with a few other household items, you can create a sudsy elixir that gives your grass a boozy boost.

three kind of drinks

Recipe

Ingredients:

  • 1 can of flat beer (12 oz),
  • 1 cup of ammonia,
  • 1/2 cup of liquid dish soap (preferably biodegradable),
  • 2 tablespoons of instant tea granules,
  • 1 gallon of water.

Instructions:

  1. Pour the flat beer into a large container or bucket.
  2. Add ammonia, liquid dish soap, and instant tea granules to the beer, and stir the mixture well to ensure all ingredients are evenly combined.
  3. Add one gallon of water to the mixture and stir again.
  4. Pour the solution into a hose-end sprayer or garden watering can with a sprinkle head.
  5. Evenly distribute the beer-based fertilizer across your lawn, making sure to cover any areas that need an extra nutrient boost.

Extra Tips:

  • To make flat beer for this recipe, simply open a can or bottle and let it sit at room temperature for a few hours before using it.
  • Be sure to use liquid dish soap that’s free from harsh chemicals, as these can harm your lawn or the environment. Biodegradable dish soap is a great option.
  • If you don’t have instant tea granules on hand, you can substitute them with 1/4 cup of blackstrap molasses, which also provides essential nutrients to your grass.

Just remember, while your lawn might appreciate a cold one every now and then, moderation is key. Use this beer-based fertilizer sparingly to avoid over-saturating your turf.

Epsom Salts: A Magnesium-Rich Remedy for Tired Turf

Epsom salts aren’t just for soaking sore muscles; they also contain magnesium and sulfur, both vital nutrients for healthy lawn growth.

Recipe

Ingredients:

  • 1 cup of Epsom salts,
  • 1 gallon of water.

Instructions:

  1. Measure out one cup of Epsom salts and pour it into a large container or bucket.
  2. Add one gallon of water to the container, stirring well until the Epsom salts have completely dissolved.
  3. Pour the dissolved Epsom salt solution into a garden sprayer or a watering can with a sprinkle head. 
  4. Evenly apply the solution to your lawn, making sure to thoroughly cover any yellow or patchy areas that need an extra boost.

Extra Tips:

  • You can also use this solution to spot-treat specific areas of your lawn that show signs of magnesium deficiency, such as yellowing blades of grass or slow growth.
  • If you have hard water in your area, consider softening the water or using distilled water for this recipe, as it will help the Epsom salts dissolve more effectively.

Not only will this treatment give your grass a lush, green hue, but it’ll also help strengthen its roots and improve nutrient absorption. It’s like giving your lawn a spa day!

Soda Pop Spritz: A Fizz-tastic Fix for Lackluster Lawns

Who knew that soda pop could be the secret ingredient for a vibrant yard? The sugar in soft drinks stimulates beneficial microbes in the soil, while the phosphoric acid promotes root growth.

Recipe

Ingredients:

  • 1 can of flat soda (12 oz),
  • 1 cup of household ammonia,
  • 1/2 cup of liquid dish soap (preferably biodegradable),
  • 2 tablespoons of molasses,
  • 1 gallon of water.

Instructions:

  1. Pour the flat soda (you can make it the same way as you make flat beer) into a large container or bucket.
  2. Add ammonia, liquid dish soap, and molasses to the container with the soda, and stir the mixture well to ensure all ingredients are evenly combined.
  3. Add one gallon of water to the mixture and stir again.
  4. Pour the solution into a hose-end sprayer or garden watering can with a sprinkle head.
  5. Evenly distribute the soda pop spritz across your lawn, making sure to cover any areas that need an extra nutrient boost.

Extra Tip:

  • If you don’t have molasses or blackstrap molasses on hand, you can substitute it with two tablespoons of instant tea granules, which also provide essential nutrients to your grass.

Not only is this recipe fun and easy to make, but it’s also an excellent way to use up any leftover soda from your last backyard barbecue.

Minty Magic: A Mouthwash Fertilizer for a Refreshed Lawn

Believe it or not, mouthwash isn’t just for freshening your breath; it can also work wonders on your lawn! The alcohol in mouthwash acts as a natural pesticide, warding off insects and grubs, while essential oils like eucalyptus and peppermint deter pests and stimulate microbial activity in the soil.

mint drink

Recipe

Ingredients:

  • 1 cup of mouthwash,
  • 1/2 cup of liquid dish soap (preferably biodegradable),
  • 1/4 cup of ammonia,
  • 1 gallon of water.

Instructions:

  1. Pour one cup of mouthwash into a large container or bucket. Make sure to use a sugar-free, alcohol-based mouthwash to avoid attracting pests.
  2. Add the liquid dish soap and ammonia to the container with the mouthwash, and stir until the mixture is evenly combined.
  3. Add one gallon of water to the mixture and stir again.
  4. Pour the solution into a hose-end sprayer or garden watering can with a sprinkle head.
  5. Evenly distribute the mouthwash fertilizer across your lawn, making sure to cover any areas that need extra attention or pest protection.

Extra Tips:

  • If you prefer a more natural alternative, you can substitute the ammonia with 1 cup of black coffee or 1 cup of compost tea to provide essential nutrients to your grass.
  • Avoid using colored mouthwash, as it may tint your lawn with an unwanted hue. Stick to clear or natural-colored mouthwashes for this recipe.

This unconventional fertilizer will not only protect your grass from unwanted intruders but also promote healthy growth.
