You may have seen them at some time in the nurseries, and you have even thought that they only serve to decorate. But the truth is that clay balls are excellent for improve drainage of the substrates. And there are many plants that do not tolerate excess water, such as cacti and succulents. For this reason, in addition to choosing a soil that has everything they need to feed and grow, it is important to ensure that it drains quickly.
But What are clay balls? And how are they used?
What are clay balls?
These balls are made with clay, as the name suggests. They are cooked at very high temperatures, which causes their expansion. They are, therefore, natural, as well as light. They have a diameter of more or less 1cm, the perfect size to prevent them from coming out of the holes in the pot 🙂.
And if this seems little to you, you should know that they are inexpensive. To give you an idea, a 6l bag costs about 5-9 euros.
How are they used?
Clay balls have several uses in gardening, which are:
10% mixed with peat, compost or mulch type substrates
We will get the roots of the plants are better aerated, which will help them grow stronger and healthier.
Placed on the plate in the pots
This prevents the roots from being in contact with excess water. What's more, high humidity is maintained which will undoubtedly do the plant a lot of good.
As mulch for plants
It is decorative and functional. The earth will not dry out as quickly, since the clay balls will prevent, or at least slow down, the passage of the sun's rays to the ground, so it will remain humid for longer. Thus, we will save water.

Clay balls for cacti
Cacti, and actually most succulentsThey need to grow on land with excellent drainage. They are very sensitive to over-watering, so one of the things to do to take good care of them is to make sure that excess water from irrigation can be easily drained.
One way to do it is mixing black peat with clay balls in equal parts. In any case, if you live in an area where the humidity is very high, it is better that you put more balls of clay than peat in that mixture.
