Subject: transplanting Cypripedium acaule
With regard to David Mellard's (and others who might need to do this)
impending rescue of Cypripedium acaule from real estate development, there
was an article (last year, I believe) in the _North American Rock Garden
Society Bulletin_ which describes successful transplantation and
establishment methods. I don't have the exact reference handy, but, as I
recall, it was very important not to cut the roots, which spread
horizontally for a considerable distance under the leaf litter. Once again
from memory - the author recommended gently lifting them up with a spading
fork inserted horizontally under the plant. I'll try to find the exact
issue, and post the information later, unless someone else on the list has
it readily at hand and can send it sooner.

I'm new to this list. However, I thought the following may be of
interest regarding Al Bickell's Cypripedium acaule rescue:
In the Spring 1996 issue of the North American Rock Garden Society
Quarterly, Don Jacobs recounts the following description of his Cyp.
acaule salvage from a very large development site (note: the "group"
that he refers to is staff from a large botanic garden that had
repeatedly failed to successfully transplant Cyp. acaule):
When I joined the group, with only my slender trench-spade and two
lettuce cartons, they looked disappointed, and said, "You know there are
hundreds of ladyslippers here. How many are you taking?" I said, "I
plan to take the first 50 I come to." The young lady who had failed in
previous attempts said, "But we filled a pick-up truck with soil and few
more plants, and they died in a year or two. How can you expect to move
them successfully in two boxes?" I explained that I would move them
bare-root. I still recall her shock: "Bare-root--but they require soil
microbes." I said, "Wrong! the symbiotic fungi are IN their roots, so
if the roots are happy, so are the fungi." I asked how they dug them,
and she explained how they used a sharp spade to lift a ball of earth
with each plant. Once again I said, "Wrong!" I carefully pushed my
narrow spade horizontally under a ladyslipper, and shook it free from
the litter as I lifted. The seldom-branched, shoestring roots dangled a
foot or more long. Since the plant's food reserves are in these roots,
successful transplanting requires minimal damage to them....At the
research garden, a site was selected that had not been previously
cultivated. It is beneath large oaks and revealed no vole tunnels. A
heavy steel rake was used to remove the litter and score the compact
soil. The orchid roots were spread flat on this interface, and the
sandy litter was scattered back over them. About 2" of wood-chip
compost was added.
Did Mr. Jacob's bare-root method succeed better than the botanic
garden's method of digging up a large root ball? The botanic garden's
method had a success rate of zero. Mr. Jacob states that the 50 plants
he transplanted in 1992 had grown to 66 crowns (40 of which produced
flowers) by 1995.

The best thing that you can do, when you "rescue" those acaules, is to
take as much of their original soil as possible! Don't use your best
soil, just fill in the hole with the original soil, pine needles, humus,
and everything. If there is enough, that should do the trick. Acaule is
actually very easy with the right soil, and the best soil is where it is
already growing! Take care, Eric Muehlbauer Queens NY

Yes, C. acaule is a very heat and drought tolerant plant. While summers
on eastern Long Island are not as long or hot as Georgia summers, they
are up there. And acaules thrive. They are very drought tolerant.
Currently, there has not been any real rain at my Cutchogue house in
nearly a month, and temperatures are regularly in the 90's. This is
unfortuantely a typical summer occurence. While I water my acaules, it is
only to keep their seeds viable. The natives go without water, yet come
back and bloom every year. Take care, Eric Muehlbauer in stifling Queens

orchid rescue in the big city

From: "Mellard, David" <dam7@cdc.gov>
Subject: orchid rescue in the big city
A month or so ago, I asked for help about transplanting cyp acaule from
a commercial property that is planned for development. Many, many
thanks to those who gave me advice, lead me to an article by Don Jacobs
who has successfully transplanted acaules, and gave words of
encourgement. It is greatly appreciated.
I thought I would give you an update on my efforts. I haven't done an
exact count yet but was probably able to rescue around a hundred acaule.
I read Don Jacobs' article on how to remove acaule without damaging the
roots. This is very laborious and requires 5 to 10 minutes for a full
grown acaule and a great deal of sweat. First, I removed the top layer
of pine straw until I saw the roots, which radiate from the plant like
the spokes on a wheel. Once I've found the root tips on side of the
plant, a shovel is gently inserted beneath the roots and pushed
underneath the plant and gently lifted slightly to loosen the soil. Now
the hard part. I removed the shovel, inserted one hand beneath the
roots, and worked my fingers to dislodge the decayed pine straw and
live roots of other plants. This had to be done very carefully and oh
so slowly so that I didn't damage the acaule's roots. No easy task.
After two or three hours of this in the hot Georgia days, I have to stop
because I started getting sloppy. And then several times it rained.
Are you feeling sorry for me yet. I also got a wonderful case of
conjunctivitis from all the dust.
It is not something I would recommend for the faint of heart. The
thought of doing this as a business and selling rescued plants crossed
my mind. But this is way too much work to get $20 or so for a plant.
There'll be no business.
The acaules are now living under a couple of very old and very shady
dogwood trees. Following Don Jacob's suggestions, here's how I planted
them.
1. Removed grass and other plants leaving as much of the topsoil as
possible
2. Added a 1-inch layer of decayed pine straw collected from the
pine forest
3. Placed the acaules on this layer
4. Added another 1-inch layer of decayed pine straw
5. Added 2 to 3 inches of composted bark mulch.
I didn't have composted bark mulch so I collected decaying logs from the
forest, ran them through a shredder, and mixed in leaf compost and
shredded, fresh tree limbs. The decayed logs were so decayed I also
broke them into pieces with my hands since running them through a
shredder makes them almost powdery. The portions are probably 1:1:1. I
plan to add some lime as Don suggested, although he states that this
should be done only when the area gets at least 50 inches of rain a
year. I will also fertilize with a diluted solution soon and again in
the Spring when the acaules come back. I will also add a layer of pine
straw just before the first frost.
In addition to the acaules, I rescued Malaxis unifolia, Tipularia
discolor, and Goodyera pubescens and some other non-orchid native
plants. I have permission to go back in the Spring if the property
isn't developed and look for other natives.
Next Spring, I'll give you an update on what comes back. If you would
like some acaule seed for micropropagation, let me know.

Subject: acaule rescue
My previous posting about the acaule rescue in Atlanta went to members
of the NNAO list and to OLD. This posting is only going to NNAO list
members and is good only for them. I have some acaule seedlings and
possibly some adult plants if I get back to the woods. The acaules are
free to NNAO list members. If you have an orchid you could trade that
would be nice but I don't want to be accussed of doing this so I can get
other orchids so even if you don't have something to trade, you can
still get some acaules. Depending on how many requests I get, though, I
may run out.
This is not a first come first serve, this is not dependent on whether
or not you have something to trade. I will just put your name in
something and draw. I will try to send two or three seedlings.
My only request is that you report to NNAO list in the coming years on
how you planted them and how they faired. Maybe we can learn something
about acaules' cultural requirements. The nice thing about the
seedlings is that they are very easy to remove without damaging the
roots so in that respect they should have a better chance of survival.
I'm pretty sure shipping will be less than $6 but we'll work that out
later.
