Plant Propagation

Chazz Hesselein

Extension Horticulturist, ACES


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


SEX

Propagation by Seeds


Can see where you’ve sown seed


Simple Methods for Improving Success


Vegetative Propagation


Vegetative Propagation

Propagation by Grafting and Budding


Vegetative Propagation

Propagation by Grafting and Budding

Cleft Graft


Phloem or Bark

Scion cambium matches rootscock on wide edge

Xylem or wood


Cambium of Rootstock

Cambium of Scion


Cambium of Rootstock and Scion are aligned


Vegetative Propagation

Propagation by Grafting and Budding

“T” or June Budding


Insert bud (scion) here

Opening bud flap with back side of budding knife


Rootstock Flaps

Media needs to contact node
