The soil you use is important to make sure that your plants thrive well. Your choice of soil is what will allow your plants to get the nutrients that they need.
If you’re thinking of The Differences Between potting soil vs garden soil , it may already be a bit confusing with if is topsoil the same as potting soil and when to use each.
......The answer to this question is, no.
so, What's the difference between topsoil and potting soil?
Garden soil and potting mix may sound like the same to you, but you should know the difference.
Knowing more about these two can help you decide which one will work best with your gardening setup and the types of plants you’re growing.
The main difference between the two is that garden soil is what’s ideal to use when you have an outdoor garden. You can also use potting soil outdoors, but be sure to mix it with topsoil and other organic ingredients and fertilizers.
Generally, using either garden soil or potting soil could already work for most plants.
What’s a gardening soil?
A garden soil is what you typically use when growing plants outdoors. This is the soil that you probably first think of when you’re asked about gardening.
It’s also known as the topsoil or the soil that you can find on lands.
This type of soil is usually made up on compost and manure. It’s naturally organic, but this is also the soil that you can mix with other ingredients.
This is why you can also find commercially available and mixed garden soil in the market.
Commercial garden soils are usually mixed with products that can be helpful with what you’re trying to grow.
A lot of commercial garden soils are specifically concocted for specific plants. However, garden soils are generally heavy, dense, and a bit clumpy.
How about potting soil?
True to its name, a potting soil or mix is specifically made for containers.
This is preferred if you’ll be growing plants indoors.
This is very different from garden soil because this usually do not have any soil or topsoil at all. Some mixes may still have this but it’s typical for potting soil to be rough and well-draining because of its ingredients.
Most of the time, potting soils are made of peat moss, bark, perlites, sand, and other ingredients that can allow the mix to drain water easily.
It’s also typical for commercially available potting soils to be sterilized to avoid growth of microorganisms that can negatively affect your plants.
When you want to be technical about this, potting soil isn’t really an actual soil. It doesn’t have humus and minerals that you can find on actual soil.
However, potting soil can still be full of nutrients, especially if you use this with fertilizers.
can i use garden soil in pots?
It’s still best to use potting soil if you’ll be growing plants in containers or pots. However, when left with no other choice, you can still work with your garden soil and a few ingredients.
This is as long as you use commercially available garden soil or topsoil.
As you already know, garden soil holds moist or water longer than potting soil. If you’ll be growing plants that don’t require frequent watering like succulents, then you’ll need to get a few more materials to make it work.
Avoid using garden soil as your base when using it in a pot. Potted plants require quick drainage for you to avoid root rot. Make sure that you use pots or containers with drainage holes.
How to Create Your Own Mix with Your Topsoil
Ideally, if you’ll be making your own potting mix with the use of commercial topsoil, you just really need to mix it with organic composts or peat moss.
However, if you’ll start from scratch, here are the ingredients you should get to create your own potting mix.
Peat Moss – this has a rough texture that allows good drainage.
What you just really need to make sure is that you don’t put too much peat moss in your mix to avoid letting it hold too much water. If not sure here I write a detailed post on how to use peat moss.
Sand – You can use any sand as long as it’s course and sharp.
Like peat moss, sand can also improve the drainage of your soil. Keep in mind that sand shouldn’t be mixed with clay-based topsoil.
Perlites – this is a fluoride-based volcanic rock that’s expanded.
However, this is usually more expensive that sand and peat moss. This also doesn’t have the ability to hold water.
Vermiculite – This is an ingredient that can be used to substitute perlites. However, unlike perlites, vermiculites have the capability to hold air and water.
Fertilized loam soil – it’s best to use fertilized soil to avoid any microorganisms from harming your plants.
How to Make Your Own Potting Soil: DIY Potting Mix
Once you already gathered the materials you need, here are the steps you can follow to create a homemade potting mix for your plants.
How to Make a Soilless Potting Mix
If you’ve already made your soil mix before, then you shouldn’t have any problems with this anymore.
The only difference is that you won’t need sterilized topsoil or garden mix for this.
You can simply start with getting a gallon of peat moss and placing it in a bowl or basket.
It’s important that you moisten this mix before using it on your plants.
Comparison of Garden and Potting Soil
Here is a table of how we can compare the characteristics of both potting and garden soil.
Ranges from light to dark brown
Sand, perlite, peat moss, vermiculite, pebbles
There really is no wrong answer when it comes to which kind of soil you can use in your garden. The answer will really depend on your setup or whether you’ll be growing your plants outdoors or indoors or in a soil bed or container.
In the end, I wouldn’t really recommend using just the garden soil or topsoil alone when growing plants in a container.
It’s not also advisable to not use sterilized soil and other ingredients to create your potting mix.
You should also consider the type of plant you are growing. There are plants that can’t thrive on moist soil, while there are plants that need to be in moist soil to be able to survive.
Remember that both soil can help your plants thrive healthily.
Lastly, you can use a potting mix outdoors too. It’s not highly recommended but the nutrients in a potting mix can help outdoor plants grow healthy.
Just make sure that you use the potting mix outdoors with organic compost ingredients too.
