Things to keep in mind before reusing a pot or substrate

At some point you may have doubts as to whether the substrate and/or the pot in which you previously had a plant can be reused. Well, the answer is it depends. As a general rule, and especially in the event that we want to make seedbeds, the less use the substrate has, the better. But we can give it new uses. In the event that we want to reuse the pot, it is highly recommended to follow some previous steps to avoid possible problems.

First of all, it is important to bear in mind that if we finally do not want to give them a new use, it is convenient to throw the plastic pots in the recycling container, and the substrate can be thrown into the soil of the garden itself or used to make compost.


  • 1 substrate
  • 2 pots



The substrate can be given various uses, such as:

  • It can be reused by planting a new plant, after “cleaning” it. And, how is the substrate cleaned and what is the purpose of this cleaning? Well, it is something that is important to do, since in this way we can eliminate possible fungi and/or eggs of some insect that could harm the plant. We will proceed to water it well, conscientiously, with distilled or rainwater to which we will add a few drops of fungicide; and finally we will let it dry in the sun.
  • It can be thrown into the compost heap.
  • Or it can even be used to gradually modify the garden soil, thus providing it with more nutrients.



The pots, regardless of the material with which they are made, before reusing them, will also have to be thoroughly cleaned to eliminate any trace of pests (either insects or fungi). We will follow these steps:

  1. We will put distilled or rain water to boil in a pot.
  2. Later, we will use that water to clean the pot.
