Substrate in succulent plants

Having beautiful succulents at home is a path full of joy, but sometimes we wonder if the container they have is already too small for them or if the soil has lost its strength.

It's not a matter of changing the substrate for the sake of changing it, but of listening to what the plant is asking of us through its roots and its overall appearance.

Many people think that for a succulent to grow happily it needs a giant pot, but the reality is that these plants are quite simple and prefer smaller spaces.

The most important thing is to find the perfect balance between the size of the container and the volume of the rosette so that the plant feels comfortable and secure.

Signs that it's time for a change

There are several clear indicators that tell us it's time to get to work. The most obvious sign is when the roots start to emerge from the drainage holes at the bottom; it's the plant's way of telling us it no longer has room to expand.

Likewise, if you notice that the rosette has grown so much that the pot looks like a toy, or the plant loses stability and looks disproportionate, it's time to act.

Another determining factor is time. Although it may not be as obvious as the roots, if more than two years have passed without changing the soil , it is very likely that the substrate is depleted and the plant needs fresh nutrients to continue developing vigorously.

How to choose the ideal pot and substrate

When choosing a new home for your succulent, remember that less is more. Always opt for a container only slightly larger than the previous one. If you go overboard with the size, the soil will retain too much moisture, which is a recipe for disaster as it drastically increases the risk of root rot.

  • Makings: Keep in mind that plastic pots retain water longer, so you should water less than if you use clay pots, which are porous and allow moisture to evaporate through the walls.
  • Aesthetics and form: If your plant grows upwards, look for a tall pot; if it is more creeping or short, a flat pot will be ideal.
  • Substratum: It is essential to use a special mix for cacti and succulentsIt must be a means very airy and quick-drying, enriched with organic matter and components such as volcanic sands or pozzolans to guarantee impeccable drainage.

The right time and transplant technique

Don't even think about doing this in winter. The cold and the plant's dormancy mean that any damage to the roots can lead to fatal rot, similar to the cold-related symptoms seen in succulents . Ideally, take advantage of spring and summer , when plants are in their peak growth period and recover much faster.

If you notice during handling that the root ball has broken or that some roots have been damaged , do not water immediately. It is best to wait between a couple of days and up to two weeks before watering again.

This allows the wounds to heal and reduces the risk of fungal infections. Once you see new buds appear or a vibrant green color at the tips, you can gradually increase watering.

To finish the job perfectly, you can add a layer of volcanic pozzolana to the soil surface. Maintaining strict drainage and respecting the plant's growth cycle will ensure your succulent stays healthy, preventing excess moisture and providing an environment where it can thrive without problems.
