Practical: Producing Cuttings

  • Many perennials, shrubs, and herbs can grow adventitious roots from their cut stems

  • The use of cuttings is a straightforward propagation technique that can expand plant stock at a very low cost

  • Desirable characteristics of the plant are guaranteed in the progeny because propagation is a form of asexual reproduction

  • Cuttings can grow to full-sized plants much quicker than plants grown from seeds

  • Equipment needed:

    • Sharp scissors or secateurs

    • Potting compost

    • Pots to house new plants

    • Hormone rooting powder

    • Plastic bag to cover cutting

  • Hormone rooting powder contains auxins that promote mitosis and cell differentiation in the new root growth

  • If the cut is made just below a stem node, meristem tissue forms at the lower end of the cut
