Rooting Hormones

• Auxins occur naturally in plants
• Promote cell division, cell expansion, rooting
• Synthetic auxins available
• Naphthaleneacetic acid (NAA) and indole 3-butyric
  acid (IBA)
• solutions or powders often used in combination
• Rootone, Hormodin, Hormex, Dip N Grow

Rooting Hormones

• Why use?
• Promote rooting of cuttings
• Increase rooting percentage of many hard-to-root
  plants
• May shorten rooting time
• May improve root quality and quantity
• Cuttings of most plants will benefit from their
  use
