Are you having a hard time figuring out what type of potting soil you should use in containers for your indoor plants to inhibiting root growth?
There are two ways that you could go about this dilemma. It’s either you mix your own soil or buy premixed potting soil.
Personally, I do both and I can agree that the struggle is real because of so many choices on the shelves in my favorite supplies store.
However, when choosing the best potting mix, What you need to know is that different plants may require different types of potting soil.
When we say types or kinds of plants, we are talking about herbs, ornamental plants like cacti, succulents, and bromeliads, and also crops like vegetables such as tomatoes or lettuce.
In this article, I will try to explain how to choose the best “soil” mix that grows healthy roots, and some of the best brands you can buy for different types of potted plants.
Since you already know or at least have an idea of what would work well with your plants, here, we will tell you the best potting soil you can get in the market.
Basically, all potting soil mixes aim to nourish your plants well, just like our top pick which is Black Gold’s Natural and Organic Potting Mix.
We see this potting soil mix as the most versatile because it can be used on most plant types, whether it will be in indoor or outdoor containers.

How To Choose The Best Potting Soil Mix
The kind of plant you have will help determine the best potting soil for you to get. While there are already a lot of ready-to-use potting mixes that you can get, the ingredients used in the mixes are crucial to ensure that your plants will grow healthy.
When choosing the right potting mix (also called potting soil) that will suit your plant need, here are the things that you should consider:
The Drainage Of Potting Soil
It’s important that the soil mix you use will allow easy drainage as excessive water can drown your plants, and this could easily happen since your plant is only in a container.
What Are The Contents Of Potting Soil?
Some plants prefer moist soil like Ostrich Ferns and Bee Balms. There are also plants that can only thrive on dry soil like oregano, thyme and agave.
You need to check the ingredients in a potting soil for you to know if it has components that could aerate the mix or let it hold more water, depending on what your plant really needs.
This shouldn’t be an issue if you’re growing plants indoors with the use of grow lights.
If you don’t have to grow lights and are completely dependent on the sun, then you need to consider getting light-weight mixes.
This means that your soil won’t easily run out of water because of less light exposure.
However, for plants that will mostly stay under lights or heat, then you’ll need a potting mix that can hold water for a long time.
Organic VS Non Organic Potting Soil
Both organic and non organic soil mix can actually let your plants thrive, however, it’s always safe to say to go for organic mixes, especially if you are growing vegetables or herbs for consumption.
Potting Mix Ingredients Common To Potting Soil
The three main ingredients of a potting mix mentioned above are just the primary components.
Different manufacturers already have ready to use combinations that you can get.
However, it’s still best to know more about the other components that some potting mixes have.
Here are a few more information about the primary and other possible ingredients that different potting mixes have:
Peat Moss – This can help hold water in the potting mix as its consistency is thick.It is also a good source of organic matter.
Pine Bark – The purpose it has is to allow air circulation in your potting mix.
Vermiculite – It’s spongey in texture, and so it also helps aerate the potting mix. An alternative for this is called perlite. While some may think both have the same purpose, perlites are porous and hard.At the same time, perlites have more alkaline.
Manure – There are two types of manure that may be included in a potting mix. First is animal manure and the other is a compost.
Sand – It helps the potting soil to retain unneeded water to avoid damaging your plant’s roots.
Plant-Specific Potting Mixes
Thank heavens as choosing the best potting mix can be way easier than you think because of ready-made potting soil mix that is already explicitly labelled.
Here are a few plant-specific potting mixes that you can get from various gardening supply stores..
Orchid Mix: This is because orchids doesn’t really need soil to thrive.
Cacti and Succulent Mix: This mix is most likely rich in peat moss as it can easily dry out.
Potting Mix for Herbs: However, most herbs like rosemary, bay leaves, and lavender require really dry soil to thrive. So like the mix for cacti and succulents, potting mix for herbs are mostly light-weight.
Peat-free Potting Soil: Peat-free mixes are made to reduce the negative impact of the process of peat extraction from plants.
Which Kind Of Soil Is Great For Different Plants
After learning about the different components of potting mixes and how they really function, It can still be confusing to choose the right potting mix.
Here is a guide you can check that is based on the type of plants that you will grow in containers:
|Type of Plant||Type of soil|
|Herbs||Soil-less mix or mixes that allow easy drainage|
|Greens/Vegetables||Moist potting mixes or mixes that can hold water for a long time (preferably organic)|
|Root Crops||Organic potting mixes|
|Cacti and Succulents||Aside from cacti and succulent soil mix, you can use a potting mix that contains more peat moss, sand, or coconut husks|
Comparing The Best Potting Soil Brands
Since you already know or at least have an idea of what would work well with your plants, here we will tell you the best potting soil you can get in the market.

Here you’ll see which one would work best for growing vegetables like spinach, herbs, cacti and succulents, and other indoor plants.
How To Use Potting Soil
The use really depends on the potting soil you have.Some are already ready to use, meaning you can just put them in a pot or container and they are already all set.
There still are potting mixes that should be mixed with soil or fertilizers.
A general rule, however, is not to fill the whole pot or container with the mix that you have. Most plants only need about 10 to 12 inches of soil to thrive. It’s already inefficient to use more than what your plant needs.
There are still growers who think that they can use potting mixes multiple times.
This isn’t really the case. The most you can reuse this is twice.
The nutrients in the mix will eventually deplete as the first plants that used it will only leave a few for the next batch.

Improving Your Potting Soil
Now, we did say that it’s not ideal to reuse potting soil or mixes. However, there are still ways for you to reuse them without affecting the growth of the next plants that will use them.
This is ideal if you have the time to revitalize your potting mix and if you want less waste.
There are a few things to consider before you can reuse a potting mix without any problems. You need to check the condition of the previous plants that used it.
If it has been infested, let that potting soil go to avoid that from happening again.
The length of use is also an important matter. If you use potting soil for more than a year, then it’s best to not reuse the whole thing, but rather just half of it and mix it with a new mix.
However, if your potting soil was only used for about 6 months, then you can still reuse it without a problem.
You need to check the ingredients that your potting soil has and just add more of those in the mix.
What’s good is that you can make your mix customized, depending on what your plant needs.
Can I Use Plant-Specific Potting Mixes With Other Plants?
Yes, you can! You just need to know whether the plant-specific mix you got is considered light or heavy when it comes to absorbing water.
If you have an orchid mix, this could work fine with succulents because of the mix’s ability to absorb and dry out the water.
What Is The Difference Between Garden Soil And Potting Soil?
Basically, gardening soil is as natural as it could get.
You can use gardening soil with other ingredients or fertilizers to promote better health for your outdoor plants.
Potting soil comes in mixes since this is usually used indoors.
Growing plants in a pot or container also make the process less natural, and so potting soil mixes are curated to help plants healthily thrive in containers.
Can I Use Gardening Soil When Planting In Pots Or Containers?
Plants can survive when planted with gardening soil in pots; however, the result may get you disappointed.
Gardening soil is naturally heavy, making it more difficult for your plants to move and grow.
It also won’t work for plants that need dry soil, as gardening soil can hold water for a long time in a container without drainage.
Can I Grow Plants In Pots And Containers Without Drainage?
Even if you have the best potting soil in the market, it’s always best to use a pot or container with a drainage hole.
This will make it easy for you to maintain the water need of your plants.
