Nursery plant Propagation

1. Nursery plant Propagation

2. 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

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

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

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

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

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

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

9. Nursery Propagation Practices • Trees, like maples are grafted onto rootstock

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

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

12. Nursery Propagation Practices • Grafters then tape the bud chip onto the rootstock

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

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

15. Nursery Propagation Practices • These are just a few of the various types of propagation practices used in the Willamette Valley
