U.S. Plant Patent Act
Under the law, the grant of a patent includes the “right to exclude others from asexually reproducing the plant or selling or using the plant so reproduced.” Infringement of the patent includes the propagation or sale of a single patented rose, whether for sale or private use without permission.

Grafting
Grafting is a process by which two different plants are united so that they grow as one
Scion
Rootstock

Budding
Actually a form of graftingA single bud is used instead of a scionBudding is quicker2 main types:
T-budding & Chip budding
![Page 6: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/6.jpg)
Materials Needed
Budding knife
Teflon(plumber’s)
tape
Strip cutfrom
Parafilm to bind
Rubber band
(Just a knife and something to bind the cut after inserting the bud or chip - 4 types shown here)
Patch

Growing Rootstock
Take cuttings and plant in the fall for
budding the following summer. Don’t let
plant dry out.
Water well for several
weeks beforebudding, andwell after the
bud has healedand starting
to grow!Water-stressed rootstock is less likely to form a successful bud!

T-budding
Most common methodBark must slip, leaving cambium layer exposedOccurs only when plants are actively growing and well-watered
Note: Not a T-cut –just opened to show the cambium layer
![Page 9: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/9.jpg)
Getting Budwood
Select budwoodfrom stems that
have just flowered, where the bud is beginning to
swell
Remove all leaves. Don’t leave any of the base of
the leaf stem
Keep cool and moist, will keep several days at room
temp, a long time in a fridge
![Page 10: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/10.jpg)
Cutting the Bud
Use a sharp knifefor a clean, even
cut! Some use single edge razor blades
Cut a thin slice – from the bottom up -
not too much wood behind the bud - leave a
tail on for ease of handling
Do this step before making the T-cut! Keep bud moist while getting rootstock ready! Some place it cut-side down on their tongue! Saliva is harmless to the bud and rose sap is harmless, unless you have recently applied a very toxic pesticide!
Work quickly!
Note: I have turned
the budwood
upside down for clarity
on this photo.

A Closer Look at the Bud
From the back side.See the bud?
View from the side.We want a thin slice!
![Page 12: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/12.jpg)
T-cut in Rootstock
First cut
Secondor
vertical cut
![Page 13: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/13.jpg)
Opening the T-cut
The bark of therootstock must
“slip” i.e., it mustsplit away from
the wood cleanly!
If it doesn’t, it istoo dry!
![Page 14: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/14.jpg)
Inserting the Bud
Start to insert the bud while holding
the cut open
Try to insert bud in less than
10 seconds after
starting the T-cut!
Most common failure in budding is drying here!
Tail
![Page 15: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/15.jpg)
Starting the Wrap
Cut the tail off!
Always wrap from bottom
to top, so eachlayer sheds rain
water from layer below
Wrap should be quite firm, stretching tape as you wrap almost to breaking point!
![Page 16: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/16.jpg)
The Finished Wrap
The bud is covered with
only a wrap or two so the
bud can grow thru the film
![Page 17: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/17.jpg)
New Growth
The new growth will come right
thru the film as shown here
![Page 18: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/18.jpg)
Cut Off Top of Rootstock
The top of the rootstock can be cut off after you see a fair amount of new growth from the bud
Don’t be in too much of a hurry to cut the top off. It can be several months
![Page 19: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/19.jpg)
Chip Budding
Steps quite similar to T-buddingAdvantage: wood can be dormant, bark doesn’t have to slipCan be done any time of the year!Difficult part – matching size of chip bud to chip removed from rootstock, so cambium layers match
![Page 20: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/20.jpg)
Cutting the Bud
Don’t wait too long here. Bud and rootstock dry quickly!
Make a notch at bottom first.
Cut down at about a 30 degree angle no more than 1/6 the thickness of the stem.
Then make a tapered cut starting about an inch above the notch down to meet the notch.
![Page 21: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/21.jpg)
Prepare the Rootstock
Prepare a cut matching the ‘hole’ which remains on the bud-stick when the bud is removed
The closer the match, the more successful the chip bud take will likely be
![Page 22: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/22.jpg)
Inserting the Bud Chip
Insert the bud chip
Always wrap frombottom to top, so each layer sheds rain water from layer below
Wrap should be quite firm, stretching tape as you wrap almost to breaking point!
![Page 23: Roses John & Mitchie Moe ARS Master Rosarians November 7, 2011](https://reader035.vdocument.in/reader035/viewer/2022062803/56649cad5503460f9496f4bf/html5/thumbnails/23.jpg)
The Finished Wrap
The bud is covered with only a wrap or two so the bud can grow thru the film
Same as the T-bud

Requirements for Success
Use a sharp knifeWell-watered rootstockMake very clean, smooth cutsKeep bud moist!Work quickly when newly cut surfaces are exposed to the air!Takes practice! Use unwanted canes…
