Crew preparing multiflora stockplants for budding
in late summer.
14
Soil is pulled away from the base of multiflora
rose stock plants to prepare for budding
15
Budders box and a bag of bud sticks, kept from
dessicating in moist sack.
16
Dave Bakker sits on the box while budding. A
bundle of bud stick is stored out of the sun to
avoid dessication.
17
A bud has been cut (not shown) from the bud
stick. Basal end is pointing up. The sliver of
wood (xylem) is removed from the inner bark by
hand.
18
Freshly cut bud scion is held along side the base
of the stem of the mulitflora rose roostock
19
Outer bark at the base of the rootstock stem is
scraped away with the knife
20
Budder begins to prepare the rootstock
21
He begins by making the first horizonal part of
the T cut into the rootstock with a rolling
motion of the budding knife
22
Note the horizontal cut. Next he has made a
vertical cut which intersects the horizontal cut,
forming a T. He uses the tip of his knife to
peel back the flap of bark on one side of the T.
23
Bark flap is peeled further back to expose the
underlying wood.
24
The bark flap is held open with the spatula end
of the budding knife while the bud is slid
downwards into the pocket created by cutting the
T.
25
The bud has been entirely inserted and the
overhanging end of the bud has been cut away so
it does not protrude from the top of the T pocket.
26
A latex patch with a large staple is used to
cover the newly inserted bud.
27
The patch is stretched around the budded area
28
tightly
29
and attached from the back by forcing the
staple through the other end of the patch. Note
that the bud itself has been entirely covered
since it will remain dormant until next Spring.
30
T-bud completed and tied. Graft union formation
callusing will commence during the warm Fall
days but the bud will remain dormant until
chilled during the Winter.
31
Many rootstocks are budded in a single day.
32
This picture was taken approximately one year
later in the late Summer. After bud grafting the
previous Summer the bud overwintered dormant. By
Spring the latex patch has crumbled and fallen
off. The upper portion of the rootstock was cut
back to just above the inserted bud to force it
into growth. The new bud puts on considerable
growth during the growing season and a finished
plant is dug in the Fall, stored bareroot in cool
storage, sold, shipped, and planted out the
following Spring.
