Re: Bonnie / Marge - tree peony

Thanks again Bonnie. I do like to have several pieces of input on a problem like this and glean the best from all of it. I'll tackle the tp this weekend. What color is your Da Hu Hong TP ?

Yes, Kitty. That is the pertinent portion of the text. I'm sorry the link
didn't work better for you. I also found this site:
http://www.adpeonies.com/plantdir05.html which says something similar but
not in as much detail:

"Suckers on Tree Peonies

Sucker roots might appear around your tree peony stems in spring. If they
look different than the rest of your tree peony, they're likely herbaceous
stems from the host root. We've had some luck in swiftly yanking such stems
up and off the root. If we're lucky, the stem severs just at the host root
junction. To really solve the problem, however, (and avoid this kind of
violence to your plant) as soon as you can tell your tree peony has grown
some of its own roots, dig it up in fall and cut off all the root below the
original graft. Keep cutting back suckers, until you can dig the plant. If
sucker roots are left to grow for any length of time, they will diminish
your tree peony or worse."

There was another one I read that said to just keep pulling off the suckers,
period. However, I think I trust the first sight I gave you the most.

Bonnie, I've been trying to use the URL you gave re TP suckers, but no luck,
so I went to the home page and found what I've pasted below. Is this what
you found? Portions of it don't make sense, as if they were pasted in and
something is missing, Like- what's with the scratching and rooting hormone?
Also, I was hoping I wouldn't have to dig up the whole shrub. I'd hoped to
just dig down carefully and remove the suckers. Planting 3 to 4 inches
deeper seems drastic. Would this be safe? I will remove the suckers now,
but am unsure when the best time to dig the shrub up would be.

Here's the text:

This is very common and potentially dangerous for your tree peony. Most tree
peonies are sold as a graft on the root of an herbaceous peony. This is
called a nurse root and should just keep the tree peony going until the TP
has its own roots You can also make a slight scratch in the tp and dust
with a rooting hormone.
d: wait a year or two and follow #3 below

3.) If the TP has good roots - at least 2 or 3 roots 6 to 8 inches long, you
should locate the graft union and remove ALL of the nurse roots. Usually the
nurse roots are fairly fleshy, while the base of the TP will be woody. Keep
cutting the nurse root back until you feel the resistance of the TP. BE VERY
CAREFUL that you do not remove the TP roots.

Replant so that the TP roots are about 3-4 inches lower than before.
Fertilize with 10-10-10 and keep well watered.

This will remove all the nurse root suckers and allow the TP to grow faster
and stronger on its own roots.

DO NOT try this in the spring as it will surely kill the plant, but cut off
all herbaceous peony suckers and keep well fertilized and watered.
