>Juerg, could you please explain the way you grow temperate Pings ?
In the sixties I started with the usual 'horizontal' cultivation (clay
pots, plastic containers and the like). Due to lack of place I then
switched to a system of 45 degrees inclination which I described in CPN 4
(1), 8-18 (1975). Both methods worked but with both I was dissatisfied by
esthetical reasons. Plants in pots or inclined containers didn't look as
being in a natural environment. After further experiments I switched to
'vertical' cultivation by 3 reasons: 1) The immediate surrounding of the
plants looks more natural (e.g. for making photographs). 2) It needs much
less horizontal surface. 3) Petrophilous species usually do not grow really
well in pots but all flatland species are easily adaptable to vertical
settings.
As I got already many requests I will describe my 'lamellar wall' method
for one of the next CPN issues and I will send it also to IPSG and to
DIONEE. First I must write it.
