The Secrets of Propagating Cactus Cuttings

Cactus cuttings


  1.  Letting the cactus cutting dry in indirect, diffuse light with good air circulation is important. The larger your cutting is the longer you should wait for the cut to heal. Once the wound is completely calloused over, it is safe to plant directly in soil. Generally, 1-4 weeks is good practice. If uncertain, giving the cactus cutting added time to heal is best practice. 
  2. Container: Find a pot suitable for the size of the cutting. Aim for an equal width to depth ratio. The width of the pot should be relative to the size of the cutting. A pot with 2x the width of the cutting is good measure.
  3. Soil Plant the cactus into any readily available cactus mix to a depth of at least 1/6 the length of the cutting. A good Cactus Mix is ideal, but most generic cactus soils can also work ok for Trichocereus spices cacti. DO NOT WATER, DO NOT LEAVE IN DIRECT SUNLIGHT UNITL NEW GROWTH APPEARS.
  4. Roots: It will take a number of weeks for the cutting to grow roots and become fully acclimatized to its new environment. During this critical time, it’s important not to expose the cutting to direct sunlight, not to water, or have extremes in temperature. Keep in mind the rooting process will take significantly longer in the winter months. It is recommended to root cacti during their active growing period. Be patient, the time frame is at least a number of weeks.
  5. GrowthOnce new growth is evident through lighter shades of green around the tip or with the emergence of new stems etc. it can gradually be exposed to full sunlight and watering can slowly begin. Your cutting is now a self-sufficient cactus ready for normal atmospheric conditions.

  1. 1) Can the Trichocereus Pachanoi San Pedro crested cactus be propagated the same as your very clear and precise printed directions??
    2) When will you have stock available for this crested cactus?


  2. Hi, and will these instructions also suit lophophora williamsii cuttings? In particular, should those be planted to 1/6th the height of the plant as well? And would the type of soil be the same as recommended here? Thank you.

  3. If I had a sunny greenhouse that isn’t heated on Central Vancouver Island with natural sunlight. Can I leave Trichocereus in the greenhouse over winter if I didn’t water until new growth appears?
