If you want to change the soil for potted cacti, you should know that they can be transplanted into new pots in winter, right after 2 weeks from the last blooming. But there are a few more things that you should know about this procedure.

Move the cacti from the pots, if they are near each other or they’ve grown too much.

Generally, small cacti can stay in the same pot for about 4 or 5 years because their roots grow slowly.

Even if you don’t change the pot, it’s advisable to change the soil every 2 or 3 years, and the best time to do this is in winter.

Pots size

Desert cacti, small and round, grow very slowly and don’t need large pots. You can choose medium sized round pots twice as wide as the cacti diameter. But the cacti that grow upright and rise up quickly have long roots and need large pots. The diameter of the pot, in this case, must be at least half the height of the cactus.

Cactus in pots, resistant and yet sensitive

  • Potted cacti may seem resistant, may not need to be watered too often, or require special care. No matter the season, they need a lot of light, sunlight and heat. They can live for decades if they have the best living conditions. Instead, they are sensitive when it comes to their soil.
  • It’s advisable to buy special cacti soil or to use high quality soil from the flower shop, and mix it with sand and fine pearlite.
  • At the base of the pot, it’s advisable to put a small layer of sand to allow good drainage of the water. The roots of cacti don’t tolerate excess moisture and the water must be easily drained through the holes of the vessel.
  • To avoid pricking when you transplant cacti, use thick rubber gloves and handle them carefully not to crush their delicate stem.


During transplanting and 2 weeks after transplantation the cacti must not be watered or moved from place to place. Choose a shady space for the freshly transplanted cacti and let them spend 10 days adjusting to the new soil. Later, you can water them a bit, once a week.
