Upcycle the Potting Soil

Here is a quick and easy method to recycle your used pot soil into something more valuable. 

1- Maintain the Volume of Potting Soil

When you use the soil for the growth of your plants, it loses its volume with time. This loss of volume is due to the loss of certain ingredients that help in the healthy upbringing of the plants. You can add multiple ingredients to regain the original drainage capability of the soil.

Here are some of the ingredients that can help you with this purpose. 

  • Coir fiber
  • Peat moss
  • Kelp meal
  • Perlite
  • Fish meal
  • Rice hulls
  • Alfalfa meal

All these ingredients play an important role in improving the fertility of the old potting soil. You can also add any additional ingredient according to the nature of your soil. 

2- Microbial Addition

Once you have met the proper requirements of the volume, the next step is to maintain the microbes level of your soil. Microbes also play an important role in increasing the fertility of the soil and preventing soil deficiencies.

They help the plants to gain the maximum organic food in the form of humus. But all this is possible if you know how to add microbes to the old potting soil. 

There are two ways to add essential microbes to the soil. 

  • Purchase compost from the market.
  • Use natural methods to add microbes to your soil.

You can use any of these methods for microbial addition in the soil. Adopt the best method according to your circumstances. 

3- Mineral Addition

The next level, after the addition of microbes, is mineral addition. Minerals are one of the essential elements that help to maintain the pH of the soil. You can add minerals in two different ways.

But keep in mind that organic materials are essential to keep the potting soil fertile for a long time. 

What Are The Risks Of Recycling Old Potting Soil?
