What Is Miracle-Gro?
If you’re just starting your adventure into plants and gardening, you might not have heard of Miracle-Gro yet.
Miracle-Gro is a very popular brand that produces synthetic fertilizers.
You can find Miracle-Gro in almost every store that sells:
- plants or gardening equipment
- greenhouses
- garden centers
- home improvement stores
- and online
Miracle-Gro is advertised to everyone, especially beginners, to help their plants grow taller, fuller, and stronger.
There are a few reasons gardeners look for alternatives:
- The first is that there aren’t many organic options. Miracle-Gro specializes in synthetic fertilizers, and it works for gardeners, so they keep producing more synthetic fertilizers than organic ones.
- The second reason gardeners look for an alternative is the chemical content. It can be argued that some of the chemicals can be causing more harm than good in the soil.
Ammonium Phosphate for example. This is water-soluble and provides phosphorous for your plants that help the roots develop.
Ammonium Phosphate is also acidic, and lowers the pH of the soil, making it more acidic.
Miracle-Gro also contains urea. This too is water-soluble and helps plants absorb nitrogen more efficiently.
Urea, however, can irritate your nose, mouth, throat, and stomach.
Key Takeaway: These organic-compound chemicals help your plants in different ways, but they can be harmful to yourself and the organisms and microorganisms in the soil.

9 – Eggshells
The calcium in eggshells is great for the development of the plant’s cellular structure, which is extremely important in young plants.
Collect and wash your eggshells anytime you make eggs.
Washing them well should remove the bacteria, but the best way to sterilize eggshells is by baking them at a low temperature for several hours.
Once the eggshells are clean and dry, crush them as fine as you can.
Using a blender or food processor will create the perfect powder to sprinkle onto the soil of your plants.
From Experience: This powder can be added to indoor or outdoor plants, starter flowers, vegetables, or greenery.
10 – Coffee Grounds
If you make coffee at home, save your coffee grounds!
They are a great fertilizer for plants that like acidic soil.

After you have brewed your coffee, mix the coffee grounds into the top three inches of soil and water your plants.
Not only do they have nitrogen, magnesium, and potassium for your plants, but they also help with water retention.
11 – Compost
Compost is a great fertilizer that you can make at home.
Compost is the result of food scraps, water, soil, and microorganisms being combined.
The microorganisms that live in the soil feed off of the food scraps and speed up the decomposition process.
What is left is extremely nutrient-rich soil that you can add to the soil of your plants.
You might want to add compost to your outdoor plants, or you may get unwanted pests in your indoor plants.
Here are some things you should add to your compost:
- Yard waste (if no pesticides are used)
- Hair and fur
- Houseplants
- Shredded paper products
- Nutshells
- Teabags
- Eggshells
- Coffee grounds and filters
- Fruits and vegetables
Here are some things you should not compost:
- Pet feces
- Fats, grease, or oils
- Meat
- Dairy products
- Eggs

You will need:
- 2 gallons of water
- 2 tablespoons of non-scented Epsom salt
- 2 tablespoons of baking soda
- 1 tablespoon of bleach
Watering can large enough to hold 2 gallons of water:
- Add 1 gallon of water to the watering can.
