Let’s get into the nitty-gritty when it comes to figuring out which soil is best for your gardens and potted plants.
Can I Use Potting Soil In My Garden?
When designing a new garden, one of the most important things to have is excellent potting soil.
Considering it’s one of the driving life forces for your plants, it needs to be of the highest quality.
You’ll likely see two types of bagged soil at the store, known as either potting soil or garden soil.
Both promote optimal vitality for your plants, but they differ significantly from one another.
Unfortunately, potting soil isn’t interchangeable with garden soil, especially when it comes to in-ground gardens.
To genuinely understand the hazards of potting soil in your garden, it’s best to know how it differs from garden soil.
What Are the Differences Between Potting and Garden Soil?
There are several critical differences between garden soil and potting soil, making them best for individual purposes.
Potting soil is often the optimal choice for potted plants, while garden soil is best for your gardens.
Let’s look at the differences in greater detail.
Ingredients
By far, the most noticeable difference between potting and garden soil is their ingredients.
With garden soil, you’ll find a composition of organic materials blended with sand or natural topsoil for plants.
Most often, you’ll notice it contains composted manure from cows, chickens, or even mushrooms.
When you hold the soil within your hands, it has a heavy, wet texture with a lower pH than potting soil.
On the other hand, potting soil is often made without natural soil and contains vermiculite, peat moss, pine bark, and the like.
All of the ingredients in potting soil make it more acidic, which isn’t the best option for in-ground plants.
You’ll also find that potting soil has dense moisture, as there are typically moisture agents added to the formula.
Another significant ingredient that makes the two differ is that potting soil typically contains plant food.
This food helps ensure your plants get the nourishment they need without the need to be planted in the ground.
Moisture
Whether you have potted plants or an in-ground garden, you’ll be responsible for providing them with moisture.
That said, in-ground plants have the added benefit of digging their roots deep to access moisture beneath the surface.
On the other hand, potted plants rely on daily waterings to get the moisture they need to stay alive.
As such, potting soil typically has a moisturizing agent that keeps the soil moist.
Unlike in-ground gardens, potted plants don’t have access to natural sources of water.
If you put potting soil in the ground, it could keep your in-ground gardens too wet, causing mold and mildew.
Too much water can cause your plants to drown as well as their roots to become soggy.
Plus, they won’t be able to dry themselves out, causing your favorite flowers and vegetation to die faster than expected.
pH Levels
As mentioned, the pH levels in potting soil are notably higher than that of garden soil.
There’s no doubt your plants are picky regarding their pH because any changes in acidity can lead to plant death.
Peat moss is the primary concern for acidity, and it’s one of the primary ingredients in potting soil.
On average, peat moss is around 4.4 on the pH scale, which is a few numbers further than the neutral pH.
Unfortunately, your plants are prone to burning when exposed to lower or acidic pH, not to mention it can also affect their overall growth.
Too much acid will inevitably lead to plant death, which isn’t ideal for your nutrient-hungry plants.
Microorganisms
Potting soil has nutrients for potted plants thanks to the addition of plant food.
The problem is it lacks the essential microorganisms that your garden plants need to thrive.
These microorganisms work together to create a diverse ecosystem that provides in-ground plants with nourishment.
By using potting soil in your gardens, you’ll deprive your plants of these essential nutrients.
Your plants won’t have access to protozoa, which is helpful in eating bacteria.
There won't also be nematodes that naturally seek out contaminants.
Another benefit of these microorganisms is they help break down organic matter in natural garden soil.
As they work through the soil, they leave behind waste which helps enrich the growing area for your plants.
No doubt microorganisms are one of the most important aspects of any plant’s life cycle.
Even some of the best-made potting soil lacks these as it’s typically formulated to be sterile.
How To Use Potting and Garden Soil Together
Although it’s highly recommended to avoid using potting soil in your in-ground gardens, it’s not impossible.
You might find that garden soil is too expensive, and you’d like to offset the costs by using potting soil.
By combining the two, you can create a good mixture of nutrients that your planted vegetation will like.
With that said, you’ll want to make sure your mixture contains far more garden soil than potting soil.
For example, opting for 4/5 garden soil with 1/5 potting soil can be a great alternative to pure garden soil.
There’s no doubt there are nutrient-rich ingredients in potting soil, like peat moss, but you need to offset its negative traits with the help of the garden soil.
Another massive advantage of mixing potting and garden soil is that it works well for raised garden beds.
You’ll have the advantage of the impressive texture of potting soil paired with the nutrients of garden soil.
Final Thoughts
Asking, “Can I use potting soil in my garden?” is more common than you’d think.
Whether you’re looking to save money or enhance your soil’s texture, it’s possible to mix the two carefully.
As long as you have a significantly higher concentration of garden soil, your in-ground plants are sure to thrive.
