Soil is one of the elements you should not take for granted if you want your plants to grow to their full potential.

A lot of beginners tend to take soil for granted because the majority of them think that it is just something that is similar to dirt wherein you just dump it in the container pot and put your seeds in it.

In reality, soil is so much more than that. Speaking of pots, high-quality potting mix is required for your indoor potted plants to thrive. You have the choice of creating your own potting mix or purchasing one.

But finding a premium potting mix can be difficult to find, especially in these trying times. But not to worry, because Miracle-Gro, a company that has been in the gardening industry since 1868, created an indoor potting mix that is perfect for your indoor plants!

I have been using this product for my indoor plants for almost two years, and I must say that all of them are doing very well! In fact, both my old plants and new plants’ growth are truly remarkable, which is why I want to share my experience, knowledge, and essential details about this product with you.

To know what is so special about the Miracle-Gro Indoor Potting Mix, you will find everything you need to know in this article.

The Effects of Miracle-Gro Indoor Potting Mix To Your Plants

Based on my experience, I started using Miracle-Gro Indoor Potting Mix with only seeds because I was skeptical of its claims back then.

Not long after, I was surprised to see my plants grow at an amazingly fast rate. They went from being a seeds to juvenile-formed plants in just 2 weeks!

In addition to that, the packaging says that it feeds your plants for up to 6 months, which I personally did not wait for 6 months to see if it really was capable of feeding my plants in that long of a timeframe.

However, there was a time that I did not fertilize my plants for about 4 months with the Miracle-Gro Indoor Potting Mix and I did not find any issues at all with my plants. All in all, I do not recommend to not feed your plants after more than 3-4 months just to be safe. It is best to do it on a consistent basis (3 months at a time).

Advantages of the Miracle-Gro Indoor Potting Mix

  • 1) Feeds Up To 6 Months

Miracle-Gro indoor potting mix is capable of feeding your plants for up to 6 months! This is great if you planned on feeding your plants on a monthly basis. You will no longer have to worry about constantly feeding your plants with this product.

  • 2) Less Prone To Gnats

Unlike other Miracle-Gro products, Miracle-Gro has improved this indoor potting mix by adding protective layers to keep gnats away.

  • 3) Effective

Miracle-Gro indoor potting mix is very effective in boosting your plant’s growth. My plants even grew in a juvenile form as early as 2 weeks! And this is something that I have not experienced with other potting mixes.

  • 4) Affordable

As mentioned, Miracle-Gro’s indoor potting mix is cheap and very affordable, which is a good choice for those who are on a gardening budget.

Disadvantages of the Miracle-Gro Indoor Potting Mix

  • 1) It Contains Nitrogen

As mentioned, Miracle-Gro contains nitrogen. This is to boost the growth and development of the plants. However, the problem with this is that nitrogen is extracted from synthetic ammonium and water-soluble nitrates as well, resulting in producing off chemicals that can kill microbes, worms, and other organisms living in the soil.

  • 2) Not Suitable For All Types of Plants

This potting mix is not suitable for plants that require less humidity and moisture retention since the materials used in this mix hold high levels of moisture, which is bad for these types of plants. This can cause root rot and prevention of the roots from scattering.
