How to Trim Tall Succulents 

Tall succulents can be trimmed, or pruned, for a number of reasons. Perhaps you want to create a more compact and tidy appearance or encourage the plant to produce more leaves or flowers. Whatever your reason for trimming, it’s important to do so carefully to avoid damaging the plant.

Here are some tips for trimming tall succulents:

  1. Use sharp, clean scissors or pruning shears. This will help prevent infection and bruising of the plant tissue.
  2. Make sure the cutting tool is sterilized before each use. You can do this by wiping it down with rubbing alcohol or diluted bleach solution.
  3. Cut at an angle, making sure that the cut surface is slightly larger than the area where the new growth will emerge.
  4. Be careful not to cut too deeply into the plant, as this could damage the vascular system and lead to rot.
  5. Immediately after cutting, apply a fungicide or diluted bleach solution to the wound to help prevent infection.
  6. Allow the plant to callous over (seal itself off) before watering or fertilizing, as this can further promote infection.
  7. When trimming tall succulents, it’s best to remove only a small amount at a time. This will help minimize stress on the plant and encourage healthy new growth.
