1. Epsom Salt

Homemade Lawn Fertilizers

Epsom salt contains two elements that boost lawn grass and its lushness-Magnesium and Sulfur. Magnesium is crucial for activating chlorophyll production and helping in the absorption of phosphorus and nitrogen, while sulfur helps plants to photosynthesize.

Sprinkle five cups of Epsom salt per 100 meters square of lawn, apply it with a spreader or spray it by diluting it in water to get a lush green lawn. If you’re diluting, follow the product’s instructions. It is one of the best Homemade Lawn Fertilizers.

Recipes with Epsom Salt

Epsom Salt & Ammonia

  • Mix one cup each of Epsom salt and ammonia in a bottle. Add two-three tablespoons of this mixture in a watering can and spread it over 200 square feet of grass.
  • Alternatively, you can mix it with equal parts water to make a liquid fertilizer for covering your entire lawn.

Supplemental Lawn Tonic

  • Mix 3 pounds of Epsom salts with an entire batch of dry lawn food (20-5-10). Spread half of this mixture on the turf.

2. Ammonia

All cleaning supplies contain ammonia in the hydroxide form. Ammonium hydroxide enriches the nitrogen and hydrogen content of the soil, thus helping the grass to utilize the soil nutrients effectively and grow greener and thicker as a result.

Spray two ounces of homemade ammonia fertilizer for every 1000 square feet of your lawn. Take note of the dosage labeled on the sprayer and walk at the right speed to ensure effective application throughout the lawn. Avoid using bleach with ammonia.
