U.S. Plant Patent Act

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

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)

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

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

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!

T-cut in Rootstock

First cut

Secondor

vertical cut

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!

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

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!

The Finished Wrap

The bud is covered with

only a wrap or two so the

bud can grow thru the film

New Growth

The new growth will come right

thru the film as shown here

 

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

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

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.

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

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!

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…
