Creating your own potting mix requires a lot of research and some effort. On the other hand, purchasing one needs to be from reliable manufacturers for the safety of your plants. If you are looking for a potting mix to purchase, then I would definitely recommend to you this Miracle-Gro product!

Miracle-Gro, one of the most reputable gardening companies in the industry, has designed a planting mix that expands, nurtures and sustains your plants! It’s almost too good to be true, which is why I decided to test this planting mix a few months ago to see for myself if it really was effective or just a product full of fake claims.

And to my surprise, the results were remarkable!

This is why I would love to share with you my experience with the Miracle-Gro Expand ‘n Gro Concentrated Planting Mix, because I believe that aside from its benefits, this product will help a lot of people, especially beginners who have just started gardening.

The Effects of Miracle-Gro Expand ‘n Gro Concentrated Planting Mix

Can Be Used As Substitute

One of the strong claims of this product is that it can be a substitute for both gardening soil and potting mix. In my case, there was a time that I did not have any potting mix left in my storage room but I had a Miracle-Gro Expand ‘n Gro Concentrated Planting Mix.

So, I used it as a substitute potting mix for a few of my potted plants, and without any expectations, I was surprised to not only see my plants doing well but also see them grow at a really fast rate! Afterwards, I bought more of this Miracle-Gro planting mix and added it to some of my seedlings.

There is without a doubt that it is a good substitute for potting mix.


The Miracle-Gro Expand ‘n Gro Concentrated Planting Mix can be used for both ground applications and/or container applications.  So, you don’t have to worry about purchasing another potting mix for your potted plants or your outdoor garden, because this product can be used for both.

Grows Three Times Bigger Than Native Soil

This is one of the claims that is displayed in the packing and of course, I would say that native soil is incomparable to Miracle-Gro’s planting mix.  However, I cannot specifically say that it grows three times bigger than native soil.

Personally, I would rank it to two times bigger rather than three. Three for me is just an exaggeration but this might happen to specific kinds of plants. But for the plants that I use it on, I am ranking it to only x2, which is still outstanding.

Miracle-Gro Expand n' Gro Planting Mix Can Expand Three Times Its Normal Size

Makes Soil 40% Lighter

Due to the expansion, if it is scattered, then the claim that the soil is 40% lighter is true. I can attest to this since I did notice significant changes to its weight in my garden.

However, for my plants that are in container pots, I noticed it to be heavier instead of lighter because the expansion of the soil is sitting on top of the old soil, which makes it heavier overall.

Holds 50% More Water

If you are looking for a planting mix that holds more water capacity, then this planting mix is a great option.

This is especially if you have plants that appreciate higher water retention.

Expands Three Times When Water Is Added

When you pour water into your plants with the Miracle-Gro Planting Mix, the planting mix will expand three times as it slowly absorbs the water.

Creates 90% More Air Space

In terms of aeration, this planting mix creates 90% more air space, which is great for your plants and roots to have better access to oxygen.

Feeds Plants For Up To 6 Months

One of the features that this product advertises is that it feeds plants for up to 6 months. I personally do not rely on this, and I do not recommend it as well.  Just to be safe, I regularly feed my plants rather than waiting for 6 months.

Ships To Your Door

Another great element of this product is the service. The company offers door-to-door shipping, which means that you will not have to worry about heavy lifting.
