Miracle-Gro Garden Soil Review -

You only need to look at the results to understand what is special about Miracle-Gro garden soil. Although it has a lot of composted natural ingredients, it's impossible to know every single ingredient and the amounts of each in each bag because they are not listed specifically.

Before trying Miracle-Gro we were using other various products such as compost, manure, and other organic matter in ours and our clients' gardens. We decided to try Miracle-Gro at some point many years ago and since then it's all we use.

From the first time we tried it many many years ago, we knew it was a product we would want to use consistently in our clients gardens as well as our own. Plants do grow bigger and healthier when we use it.

So the answer to what is special about Miracle-Gro garden soil can be summed up in two words: the results. The results are what is special about this product.

As mentioned previously, the ingredients are generally identified on the bag but not specific ingredients or amounts.

This is understandable.

In the world of gardening, lots of different natural ingredients can be used to make up rich garden soil. I'm sure with Miracle-Gro it's impossible to know the amount of specific ingredients in each bag because they can vary.

As an example, would you know the exact amounts of minerals and composted organic matter in your compost pile at your home - that is, if you have one? It would be impossible.

The bag states it this way...

This product is formulated from one or more of the following: pete, processed forest products, coir, and/or compost and sphagnum peat moss, fertilizer and a wetting agent.

California this product is formulated with processed forest products, compost, sphagnum peat moss, fertilizer and a wedding agent.

In Texas and Idaho this product is formulated with compost, processed forest products, sphagnum peat moss, fertilizer and a wetting agent.

As you can see from this list of ingredients directly from the bag, you cannot know exactly what is in the bag. You just know it’s all good stuff!

In addition, there is a very small amount of fertilizer in the bag, namely .09-.05-.07. Yes, those are decimals. To find out what those numbers mean, read this article. https://gardenmasterz.com/types-of-fertilizer-and-when-to-use-which-type/

The fertilizer contained within has been specially treated to be slow-released, so it will in fact feed the plants over time.

The bottom line is Miracle-Gro garden soil is composed of all natural ingredients and the results speak for themselves.

We are being totally honest when we say we have used this soil amendment for years and have always had excellent results. It has never disappointed.

I couldn't begin to count the number of bags we have purchased over 20 plus years and I have to say the quality of every bag has always been top notch!.

We have never had any issues with other unwanted ingredients in the bags such as rocks, mulch, or anything else as some reviews on the actual Miracle-Gro website have suggested.

So does Miracle Grow live up to its name?

IMPORTANT NOTE (Full Disclosure): The above link will take you to Amazon.com where you can order this product and if you do, we make a small commission. However, on this particular product, as of the date of this posting, Amazon is priced much higher than if you were to purchase it at other garden centers and pick it up yourself. We suspect (although we cannot verify this) it's because the bag is heavy, and much of the built-in charges are for shipping. Just know before buying, picking it up at your local garden center will cost much less. Pricing and availability is always subject to change with any retailer, so it's your sole responsibility to do you due diligence before purchasing.

You said that natural fertilizers can’t burn plants but “chemicals” can… Now, I see the N, P, and K on the periodic table, but I’m not seeing a separate element for the nutrients you get from worm castings and bat guano… Can you elaborate?

I have used Miracle Gro products for over 53 years & am wondering where your pride has gone in producing your products. I have purchased 2 bags of Garden Soil that just needs to be thrown away. One bag has very little soil as it is mostly twigs and they are large twigs. The other bag is full of huge hard clumps. I have not picked up even one handful of soil. It is all clumps. I am 90 years old & still gardening & cannot tell you how disappointed I am in these products. Will not purchase anymore.

Nothing is growing well in the Garden Soil this year. The seeds that sprouted are not advancing or have already died. I planted fresh seeds of herbs and flower and they only grew to an inch and stopped. In the garden, I planted flowers that have not grown. My tomato plants should be twice their size. The soil holds so much moisture, it just doesn’t dry out . I added it to an inside pot to fill in and that was a mistake! No I have to transplant the indoor plant too.
