Potting mix is meant to stand alone, as opposed to being mixed in with existing soils. It is a self-contained product designed to provide potted plants with everything they need to grow and thrive. Garden soil is meant to be spread around. Mix garden soil in with your native dirt to improve it.
Make sure to blend the two types of potting soil as much as possible. By mixing them together you get an even blend of potting soil and your plants will do better.
Potting mix is the medium of choice for nearly all container gardening for three reasons: aeration, weight, and drainage. Potting mix is a fluffier growing medium, which allows water and air to better penetrate to the roots in the confined area of a container.

Cons of Potting Soil.
Their texture and weight allow less air movement, which is why they can get easily compacted. Water drains slower. This quality makes it not the best choice for potted plants since they can get wet roots, harming your house plants. Not perfect for seed starting.
The main disadvantage of potting soils is that it can be expensive, while soil from your own garden is free. Some plants can be harmed by a potting mix intended for another type of plant. Also, some potting mixes are not suitable for organic gardening because of synthetic ingredients they contain.
Opened bags of new potting soil can retain quality for around 6 to 12 months. For unopened and unused potting soil, you can store it for about a year or two before it goes bad. Usually, potting soil lasts longer when stored in a dry and cool container.
The Lifespan of Potting Soil
Fortunately, most potting soil can last up to two years because that is the lifespan of the peat moss it likely contains. (Tip: To keep it as fresh as possible, store it sealed in its original bag or another covered container in a climate-controlled environment.)
Compost recharges and adds incredible structure the soil. The finer the compost is, the better for potting soil. Next, add in the worms castings. As for how much to add, 2 to 3 cups of castings for every 5 gallon bucket of old potting soil is a good rule of thumb.

Legionella longbeachae, a bacteria commonly found in potting mix, can cause Legionnaires' disease, a form of pneumonia. This disease is often caused by inhaling or by spreading the bacteria from hand to mouth after handling potting mix, soil or compost.
If you notice a rotten egg smell coming from your potting soil, it's a sign that it's gone bad. The bad smell is caused by bacteria and fungi that are breaking down the organic matter in the soil. It still can be used if you spread it out on a tarp and let it bask in the sun.
After 6-12 months most bags of potting soil have lost some, if not most of their nutritional value, but they are still safe to use. It just won't have optimal food to feed your plants. Most potting soil can be stored 1-2 years without spoiling if stored properly, but its nutrients will still degrade.

If it's been awhile, and your plants aren't performing well, maybe it's time you looked into it. Typically, changing the soil in your potted plants should happen every 12 to 18 months. There are some exceptions that may change this timing.
If you use garden soil, such as Miracle Gro Garden soil or Vigoro Garden soil you may run into some problems. Garden soil is simply too heavy, making containers much harder to move around than if you used potting mix. That extra weight will lead to compaction from watering.

When filling pots with potting mix, they should never filled to the top. Smaller pots are usually filled at least 1cm (3/8”) below the top. With larger pots, leave a space of 2cm (3/4″) or more. This empty space makes watering easier, and prevents the potting mix and any fertiliser applied to the pot washing out.
