Trimming a cactus might seem daunting, but with these step-by-step instructions, you’ll be a pro in no time!

  1. Prepare Your Cactus: Using your tongs or wrapped-up newspaper, gently hold the cactus in place.
  2. Identify the Cut Area: Look for the areas that require trimming, whether they’re overgrown, damaged, or diseased.

  5. Dispose of the Cuttings: Safely dispose of the cuttings or consider propagating them if they’re healthy!
