Cacti are among the plants that are easy to grow, it is still necessary to know their specificities which differentiate them from the usual green plants.
Passionate Yann Cochard, author of Cactus (La Plage editions), gives us his little "tips" to take care of our cacti.
1. Water the cacti well
“Contrary to popular belief, cacti need water. They can go without for long periods of time, but if you want to watch them grow and flower, you have to water them! "
How? 'Or' What ? Abundantly (all the soil must be wet) but without letting the water stagnate in the pot or at the foot. The soil must then dry out until the next watering ...
On the other hand, cacti need winter rest, that is, stop watering from fall to early spring, by being placed in a cold and dry place. "
2. Provide them with a good substrate
Garden soil, good quality potting soil and coarse sand in equal quantities: this is the soil cacti appreciate. “It must be very draining. You can also replace the sand with pozzolana, perlite or vermiculite.
Be careful with "ready-to-use" mixtures available on the market, which are better to mix half with sand or any other draining element. And to keep good food for the plant, annual repotting is recommended, or even every 2 years.
Finally, adding liquid fertilizer can be beneficial during the growing season ".

3. See your cactus bloom
Light ! Place them near a window, but above all, take the time to acclimatize them step by step until they are as bright as possible (ideally on a veranda).
Although they love heat and light, placing them directly in direct sunlight behind a south-facing window could create thermal shock.

4. Cut the cactus
“Cut off one end of the plant and root it in a cool, airy place (about a week) to produce a new plant. When the roots appear, place the cutting on the substrate and water lightly only ”.
The simplest cuttings to make are for Mamilliaria and Rebutia since all you need to do is remove one of their round shoots.
5. Choosing the right cactus
If you prefer a "candle cactus", opt for the Myrtillocactus geometrizans or the Euphorbia ingens (which is actually a spurge), very graphic.
On the side of the classics, we find Opuntia microdasys (also called rabbit ears), Ferocactus latispinus (nicknamed devil's tongue), or Astrophytum myriostigma (called bishop's cap).
If you are looking for a little originality, choose a Chamaecereus silvestrii (corcnichon cactus), an Aporocactus flagelliformis (rat tail) or an Echinocereus rigidissimus ... Think, finally, of Easter cacti and Christmas cactus !
