Tomatoes are an essential part of anyone’s diet and what can be better than growing them in the backyard of the house.
Now these juicy fruits generally thrive in most types of backyard soil except if there is heavy clay content. That is because heavy clay can be very dense, which might prevent roots from developing in the right way.
Moreover, while the roots love moisture, they may rot if there is too much stagnant water. Hence, the soil needs to be rich, organic, and well-draining. If you are not sure about the type of soil in your garden, then store-bought soil mixes can come to the rescue.
Hi! I am Stacy Smith, and today I am going to tell you about the best soil for tomatoes in pots. I have also added a buyer’s guide in the end so that you can make the right decision.
So, without further ado, read on!
Top 5 Soil For Tomatoes In Pots
1. Miracle-Gro Expand 'N Gro 70767430
One of my top recommendations which can work as a replacement for soil or potting mix is the Miracle-Gro Expand 'N Gro 70767430. I was looking for something that could be used in pots as well as on the ground, and this fit my needs well.
Product Highlights
Now the native soil at your place may not be suitable for growing tomatoes as it may not have the right mix of ingredients. And that is where this planting soil comes in.
So, I will recommend adding water to this soil and then putting it in pots or on the ground. It can absorb a lot of water and expand when water is added. You should mix a one-inch layer of this mix with four to five inches of soil from the ground. The soil will expand three times and create 90 percent more air space.
Next, you should know that this mix ensures that the plants grow 3X bigger than if they were just planted in native soil. You will find good quality fertilizer and coir in the mix, which helps in the growth process.
What’s There To Like About It?
One thing about this mix that I really liked is it can be used for a large number of plants. Since it increases three times in density, you can evenly spread it across a larger area in numerous pots.
Moreover, I noticed my tomatoes growing well in this type of soil. They developed a bright red shade and looked very healthy. Just remember to water the mix beforehand; otherwise, the plant may be pushed out by the expanding soil.
What’s There Not To Like About It?
The mix contained a spider in it, which came out as soon as I opened the pack. But this is common while buying fertilizers, so you can wear gloves when opening and dealing with the mix. Just remember to do this outside the house so that spiders do not enter the house.
Pros and Cons of Miracle-Gro Expand 'N Gro 70767430

2. Espoma AP8
Up next is a product that works well for both indoor and outdoor plants. The Espoma AP8 is a potting mix that can be used for a large variety of vegetation, including herbs, vegetables, and flowers. Read on to know more!
Product Highlights
To begin with, this organic soil comes with a rich mix of ingredients, including humus, sphagnum peat moss, and perlite - mixed with kelp meal, alfalfa meal, feather, and earthworm casting. Hence, you can already understand how healthy it would be for plants.
Next, you will get a blend of endo and ecto mycorrhizae, which makes it all the more healthier. The natural ingredients mix well with the soil, and there are no harmful foreign substances added to it.
Moreover, if you are wondering when to use it with soil, I will recommend adding it when you are planting seeds or transplanting. The latter is often needed for the plants to get more space to grow. So, wait for the right time and then add this organic mix to the soil.
What’s There To Like About It?
When the soil first arrived, my husband found the dark-rich organic matter to be perfect for the plant babies. The soil is soft and light, and will allow water to pass through. As such, I was able to use it for cucumbers, broccoli, lettuce, as well as tomatoes.
So, my entire vegetable garden patch received all the needed nutrients, thanks to this, and the leaves turned greener and healthier.
What’s There Not To Like About It?
The only problem with this mix is that it is pretty expensive. Hence, the average homeowner may not be able to afford it for large gardens as the person will need to purchase more than one pack. But if you are planning to grow a few tomato trees, then this is a great option.

3. Perfect Plants Potting Mix
One of the best all-natural mixes available on the market is the Perfect Plants Potting Mix. It is enriched with a number of ingredients that will work with plants in containers or pots, and you are going to love the natural blend.
Product Highlights
This product comes with all the necessary ingredients needed for indoor vegetation and outdoor tomato plants. It is specifically known for moisture management as well as absorption of water by the soil.
That said, there are three things present in the mix, namely Perfect Plants perlite, coconut coir, and peat moss that ensure proper water retention. Then there’s Mycorrhizae, composted pine bark, worm castings, and lime, which help in achieving the perfect pH balance.
The Mycorrhizae in the soil will help in the growth of roots as well as in flushing out harmful bacteria. This leads to better plant yield, and you will notice a greater production of tomatoes. Meanwhile, you can look forward to great drainage as the materials will prevent the soil from becoming compact.
Moreover, you will get eight quarts of the dry mix in a resealable bag. Hence, all of it does not need to be used at one time.
What’s There To Like About It?
Coconut coir is added to this mix, which makes it all the more special. It ensures that there are air pockets in the soil, allowing water to drain and air to pass through.
Also, the worm castings will lead to vibrant and luscious green foliage. This makes the root system better, and you can see the tomatoes turn a bright shade of red. I also found that as a result the tomato plants survive environmental change better.
What’s There Not To Like About It?
There might be a few insects in the bag, and they could bite. I learned it the hard way; hence, I will recommend you to wear gloves while working. If there are no gloves, then you could also use a cloth to cover your hands. Just make sure that your hands are well protected, and you should not face any further problems.

4. Black Gold 1302040
I was looking for an all-purpose potting soil mix when I came across the Black Gold 1302040. It is a good quality option - known for its performance and growth-enhancing capacities. You can read on to know more about its bells and whistles.
Product Highlights
First of all, this soil will not only work for tomatoes but a huge range of other vegetables and blooms. You will love the rich and loamy mix, which can be used for all kinds of gardening needs. The soil contains aged and composted bark, Canadian Sphagnum peat moss, earthworm castings, pumice, horticultural grade perlite, along with organic grade fertilizer.
Moving on, you can use it in patio containers, hanging baskets, vegetable planting pots, or directly on the garden soil. It will work well, ensuring you get premium quality flora and fauna.
Furthermore, every pack contains about 5.63 pounds of the mix, which should be sufficient for a few tomato plants. You can always order more packs if required. It is easy to handle, and you can use it while repotting or planting new seeds.
What’s There To Like About It?
I specifically loved the fact that there was pumice and perlite added to the mix. Both of these prevent the soil from becoming compact and ensure that there are air spaces and pores in the soil. This has helped my tomato plants grow better and healthier.
Plus, the soil did not need to be mixed with anything else. It already came with all the required ingredients; all you need to do is add it to the existing soil.
What’s There Not To Like About It?
The mix does not contain coconut coir, which can help in making air spaces, but then there are other materials in the mix, which can help with that. Now, if you still wish to get coconut coir, then you add it to the mix while working. Just keep it near the base so that water drains well and there is no accumulation.

The formula is MycoApply certified and OMRI listed, making it safe to be used anywhere with pets and people around. It can be used in pots both inside and outside the house. And it is the perfect match for tomatoes and other vegetables, plants, and flowers.
Meanwhile, some people use it for soil amendment in the garden to ensure that bare roots will be able to get all the nutrients needed.

Additionally, the soil comes with TruBiotic soil microbes along with ecto and endo mycorrhizae. These will together make your tomato plants grow faster and look brighter.

Buyers Guide
If you want to grow a beautiful tomato garden, then the right kind of soil will make it happen. However, it may still be difficult to find the right mix; hence, I am curating this buying guide to help out.
1. Purpose
Do you just want to grow tomatoes, or are you considering a vegetable garden? There are various kinds of soil mixes that are suitable for different purposes. Some might work well for tomatoes but not other vegetables. That said, purchasing multiple packs may mean spending a lot of money, which you might not be ready to.
So, please ensure you make a list of the plants that you are going to grow before buying. If you are looking at flowers as well as tomatoes, then there will be separate soil mixes. The same goes for vegetables, fruits, or herbs. You will find all-purpose mixes, which may suit most flora and fauna.
2. Area Of Application
Some potting mixes act as a replacement for soil in baskets, patio containers, and vegetable plant pots. These may work for individual pots but not for plants that are directly planted on the ground.
On the other hand, there are options that can be used both for pots and soil. In such cases, I generally mix a part of the soil mix with the existing soil in the backyard, and I then plant the seeds.
Moving on, another consideration is where you plan to use it for indoor or outdoor plants. The former may require a certain formulation, which may not be present if you are purchasing a mix for outdoor plants and using it for indoor ones. Hence, read the back of the pack carefully before purchasing.
3. Organic Mix Of Ingredients
I do not believe in using any kind of artificial ingredient or chemicals for my plants. So, my husband and I would keep fertilizing the soil with natural compost once in a while. However, it was not possible anymore; hence, I shifted to using these potting mixes.
Here, I would highly advise that you use an organic mix as tomatoes are usually grown to be eaten. You would not want to consume chemicals that have seeped into the fruits from the ground.
Also, the soil needs to be well-draining and rich in nutrients. Some mixes have coir in them, which increases the presence of air pockets, which ensure that water flows through and does not lead to the formation of compact soil.
If not coir, please check the mix well for any kind of fiber as that allows good water drainage. When excess water stays in the soil, it may lead to the rotting of roots, which can eventually kill the plant.
Moving on, other options come with aged bark, earthworm castings, Sphagnum peat moss, perlite, and pumice, to name a few ingredients. The presence of each is important in creating a rich loamy mix.
Here, I will just leave you with a word of advice. Please wear adequate safety gloves before opening the bag and taking out the mix. There might be some live insects in the bag, and you do not want to be bitten by them.
4. Amount
How much area do you wish to cover with the soil mix? If you are purchasing an expensive product and have a large garden to look after, then you might end up spending loads of money. That is because multiple packs will be needed, increasing the overall expenses.
Hence, make a note of how much soil you might require and then calculate the expense in the beginning. This will keep you from going over your budget while still purchasing enough soil for the plants.
5. Safety
If you have pets in the house, it is best if you can use an organic formula that will not harm them even if consumed. There are such formulas on the market, and I have discussed one in the above section. Also, please read the back of the pack carefully to know about it before purchasing.
Frequently Asked Questions
Here, I will be discussing some of the questions that people generally ask when it comes to growing tomatoes in pots.
The size that is generally recommended is 10 gallons, but you can opt for something even larger if the plant demands that.
It is best if you do not add composted manure for tomato plants. The manure may be too concentrated and strong, eventually burning the roots of the plants.
If you are trying to increase the pH level, then you can add ground lime to the mix. To lower it, you can add peat moss or compost, both of which are going to work well. But please remember to be careful about the amount as you do not want to overdo and change the pH level altogether.
My Final Recommendation
I have finally reached the end of this guide about the best soil for tomatoes in pots and it is time to wrap it up. But before doing so, let me take you through my favorites.
The Miracle-Gro Expand 'N Gro 70767430 is my favorite choice because of its excellent efficiency. On the other hand, the Espoma AP8 will work with both indoor and outdoor plants. And the Perfect Plants Potting Mix comes with a very nutritious natural blend.
Now, remember that when you open a bag, you should be well covered. Do not take any kind of risks as there can be insects in the bag, considering these are all organic mixes.
On that note, take care and happy gardening!
