Plant Propagation

Chazz Hesselein

Extension Horticulturist, ACES


Plant propagation

Plant Propagation

  • Sexual Propagation (propagation by seeds)

    • Mixing of genetic material of parents

    • Seeds cheaper

  • Asexual Propagation (vegetative propagation)

    • Production of clones (genetically identical to parents)

    • More expensive than seeds

Propagation by Seeds


Plant propagation

Can see where you’ve sown seed

Plant propagation

Best chance of success if a node is in contact with media


Plant propagation

Media needs to contact node
