What Fertilizer Do They Use in Miracle Gro Potting Mix?

It’s no secret that Miracle Gro helps plants proliferate. So it shouldn’t come as a shock that there is fertilizer in this potting mix. However, you are probably wondering what kind of plant fertilizer works so well.

They use Synthetic fertilizer in Miracle Gro Potting Mix. This synthetic fertilizer releases slowly into the soil once activated with water. The fertilizer will then provide nutrients to the plants for up to 3-6 months before becoming depleted of nutrients. 

Most synthetic fertilizers come from factories that combine nitrogen with hydrogen and methane, creating ammonia. However, each fertilizer’s overall creation process will differ depending on its ingredients. AllThough, manufacturers produce all synthetic fertilizers in factories or laboratories.

Fertilizing plants is essential to reaching optimal plant health and growth. Each potting mix comes with varying levels of nutrients and ingredients. So what exactly does Miracle Gro contain? 

Miracle Gro Potting Mix ingredients:

  • Aged bark fines
  • Perlite
  • Plant food

Each of these ingredients helps to provide added nutrients to the soil to feed your plants since there is a good combination of fast and slow-release nutrients. Next, I would like to discuss the exact percentages of essential nutrients in the Miracle Gro Potting Mix. 

Miracle Gro’s Fertilizer Nutrients:

  • 0.21% nitrogen: This nutrient allows your plants to capture more sunlight which they can turn into food to help them grow. 
  • 0.07% phosphorus: Phosphorus aids in taking in sunlight and converting it into usable energy for the plant. 
  • 0.14% potassium: This helpful nutrient increases the movement of water, nutrients, and carbohydrates through the plant’s tissues to speed up growth and promote overall health. 

These nutrients work together to help produce larger, healthier plants which is one of the reasons Miracle Gro is so popular. This excellent potting mix contains almost everything your plants will need and is much simpler to use than your homemade soil if you are new to gardening.

Is Miracle Gro Potting Mix Good for All Plants?

This potting mix is popular among the gardening community, and Miracle Gro is often marketed as a product that you may use on any plant, but is that true? Is Miracle Gro Potting Mix suitable for ALL plant types? 

Miracle Gro Potting Mix is good for all plants. This potting mix is known for aiding plants in growth and fruit production. However, Miracle Gro might not be a good fit if you are trying to have a completely organic garden due to its synthetic fertilizer content. 

Many gardeners use this potting mix because of its simplicity and the fact that it works so well. You can use the soil mix on anything from fruit, vegetable plants, flowers, or bushes. This fertilizer does a great job with hard-to-grow plants like gardenias.

How To Use Miracle Gro Potting Mix

Next, I will discuss using Miracle Gro Potting Mix properly in your garden. However, before we get started, there are some items you will need to acquire. 

What you will need:

  • Miracle Gro Potting Mix
  • A hand shovel
  • A hose
  • A plant pot or other container with good drainage.

Steps for using Miracle Gro Potting Soil:

  1. Select your planting vessel. You should aim for a pot or container with holes in the bottom to allow for proper drainage. Poor drainage can lead to mold and root rot in your plants and soil. 
  2. Fill the bottom of your pot ⅓ of the way up with the potting mix. This measurement doesn’t have to be exact. Simply do your best to add in the new soil and stop when it’s ⅓ of the way up. 
  3. Add in your plants. If your plants are larger and have well-formed roots, loosen them before positioning them in your pot. 
  4. Fill in the rest of the pot with the potting mix. Cover all of your plant’s roots and gently pat down the new soil. Be sure not to add too much mixture as you need space for water to be absorbed.  
  5. Water your plants. Give your new Miracle Gro plants a good watering. Be sure to saturate the soil to unlock the nutrients thoroughly it contains and to give your new plants a nice drink. 

The same steps can still apply if you use this mix on a large scale, like in a garden bed. Simply fill up your container ⅓ of the way from the top before planting. Then add the remainder of the dirt and follow the rest of the steps. 

It’s important to note that Miracle Gro Potting soil only lasts about six months and will need to have fertilizer added or new soil mixed in to continue providing nutrients to your plants. You can do this easily by adding compost or a new bag of potting mix. 

So as you can see, the overall process for using Miracle Gro on your plants is simple. However, if you are a visual learner, I recommend watching Miracle Gro’s Video on how to use their product. They do a great job of showing you exactly what to do quickly.
