No. You should replace it with fresh soil every year, so your plants get the nutrients they need to flourish.

Here’s why:

1. The soil might be contaminated

If you’ve ever dug up a plant and seen all the little critters and bugs underneath, then you know what’s actually living in your garden. These creepy crawlies are beneficial for some plants but not others.

2. The soil itself could be contaminated

Many pesticides are designed to stay on the plant for a long time. They don’t wear off, and they can actually seep down into the soil below. This means, if you planted your garden with this same soil year after year, you might be getting more pesticides than nutrients!

3. The soil has probably aged

Do you know how an older population is prone to have a lot of medical issues? Well, the same goes for soil. After being manipulated and used many times, it loses its nutrients. That’s why you should buy fresh soil every year.

4. If you reuse your container garden soil, it could become compact and hard

You might not think this is a big deal until you can’t plant anything in the area anymore. Softer soils let air and water flow through them freely. When they get compacted, they lose that benefit – which means your plants will die off without proper access to air and water.

Soil is an important part of any garden, but you should always buy fresh soil to replenish your planting area. If you reuse the same soil year after year, it could actually be toxic to your plants.

What is some good container garden soil to buy?

There are different types of soils that you can use in your containers. Here is some commonly used ones:

  1. Miracle-Gro Moisture Control Garden Soil is a popular choice for container gardens because it can retain water up to 5 times its weight. This saves you the trouble of having to constantly re-water your plants.
  2. Miracle-Gro Shake ‘n Feed All Purpose Plant Food spikes nutrients into the soil to give your plants the nourishment they need to grow. Two other popular choices are Fertilome Potting Mix and Miracle-Gro Potting Soil.
  3. An inexpensive option is planting in an old, clean pair of panty hoses. You can tie off the ends and hang them on your balcony or patio. Just wait until the seeds sprout before removing them from the hosiery – they’ll need to have access to some air until then!
  4. When you buy new soil, always make sure to aerate it thoroughly before you plant. This means turning the soil over and mixing in some air so that your plants can breathe. They will grow happier and healthier if they have access to plenty of nutrients and good circulation!


A container garden should have its own fresh, new soil every year because it hasn’t been depleted of nutrients and is at risk of being contaminated by pesticides and fertilizers. If a plant has a pesticide on it, the pesticide will be taken in by the plant and eventually lead to the soil. The soil will also be contaminated by fertilizers because they are made of chemicals that cause it to lose nutrients over time. It is important to only use fresh soil every year, so your plants get nutrients that keep them alive, healthy and produce quality fruits or vegetables.

As long as you washed the container thoroughly and didn’t plan on eating anything out of it. If you plan to store extra soil or make more planting areas with it, make sure to let the soil sit outside for a few days before putting any plants in it. This allows time for any chemicals to dissipate into the air.

You can reuse container garden soil. However, there are some problems with reusing the soil that you should be aware of. For example, if you reuse your old potting soil without properly preparing it for another planting season, this could lead to poor quality vegetables or fruit because the nutrients in the soil will have been depleted or altered over time. Also, it is important to note that if you are reusing soil in the same pot or planter box without removing any of the old soil (which can be difficult due to roots), this will result in an unhealthy environment for your plants because there might not be enough room for air circulation and your plants may suffer from poor development.

A good rule of thumb is to leave the soil for a year before reusing it in another container. This allows time for any leftover pesticide or fertilizer to dissipate into the air. However, if you are planning on planting something that will not be harvested until after a few months, then this may not be necessary. Read more about how to improve Drainage here!
