I have another
method that has worked for me. If you have a division with a sported leaf or
two, you would want the bud under that leaf to sprout. What I do with these
is wait until early Oct. and remove all the leaves whose buds I don't want to
sprout and then scrape off the buds. I leave the leaves I want buds from alone.
Before planting again, I dust the plant with a little Benlate. It's pretty much
guaranteed that the one you want will come up in the spring. You will get
to keep the size that way, but it doesn't isolate as well as your method does.
There are four methods used for crown
divison/multiplication. They are Bud Cuttings (Alex Summers
method) Rossizing, ( the method introduced by Henery Ross)
Zumberizing, (Bill Zumbar) and Bud Isolation , ( Ran Lydell's
method.) All these "processes" are done in late summer/early fall.
Bud Cuttings - Individual buds , from the basel area are carefully
removed. Ideally each has a bit of root. These can be planted in a
high humus soil. They will come up in spring looking a bit like Tc
plants. Rossizing - Carefull cuts are made through the entire basel
area, starting where the leaves connect. A sharp , knife is pushed
through the base & out the opposit side, and then pulled down ward to
the root area. On larger plants several cuts can be made. These
need to be done carefully so not to damage buds on ether side.
Zumberizing - Cuts about 1/4 inch deep are made between the buds. The
knife is pulled ( maintaning the 1/4 inch depth) down through the base to the
root area. Bud Isolation - An arch shaped cut is made over and down
between each bud. This is continued in the same manner as with
Zumberizing. In all these methods, a dusting of all fresh cuts with a
fungiside is necessary. I believe Bud Isolation works best, as it allows
the bud to be totally "isolated" but still "feed" from common root
system. The resulting plants will come apart easly in spring and will be
large and devlope quickly. This process also allow one to isolate sports
with better cances of not having them abort.
