Nursery Propagation Practices Why use
propagation? More control of
production & growth
Improved disease resistance
Sometimes, it’s fun to put multiple varieties on one plant

Nursery Propagation Practices Selecting Cutting
Stock Propagation
Manager looks for woody stems that “snap” Not too woody, not
too soft

Nursery Propagation Practices Cuttings are either taken by hand or
with a mower on a boom

Nursery Propagation Practices Cuttings are
sanitized in Physan before being stuck Sometimes
cuttings are purchased & stored in cooler until ready

Nursery Propagation Practices Cuttings are trimmed and ends are dipped in rooting hormone Cuttings are then “stuck” into rooting flats

Nursery Propagation Practices Some cuttings are
stuck in soil, but most are stuck into Perlite or pumice

Nursery Propagation Practices Once cuttings develop roots, they are
“upshifted” into the next size container

Nursery Propagation Practices Trees, like maples are grafted onto
rootstock

Nursery Propagation Practices However, it is often cheaper to graft trees in
the field This unique machine reduces fatigue for grafters

Nursery Propagation Practices Grafters cut a bud
off of the bud wood
Then they cut a notch in the rootstock

Nursery Propagation Practices Grafters then tape the bud chip onto the
rootstock

Nursery Propagation Practices Eventually, the
new bud will graft onto the rootstock and establish itself as a new tree

Nursery Propagation Practices Whip and
Tongue Graft Used to
add weeping species (Willow, Cherry) to rootstock
