Tudor Caradoc-Davies
The first Disa grower that we met during
our journey to New Zealand is perhaps the world's most southern grower of Disas,
growing them at almost 46 degrees south. Dr. Tudor Caradoc-Davies
is a former South African who obviously brought a love for his country's most
beautiful orchid with him. He resides in a suburb of Dunedin which is situated on a bluff of the Otago Peninsula overlooking Otago
Bay.
A spectacular view! Since he has many interests,
his cultivation of Disas pretty much follows the GOD system (Grow Or Die).
He grows in insulated flats placed on the ground inside 4 hoop
greenhouses measuring about 8 x 19 feet that are left open at one end to
allow for air circulation. Due to
his location, the weather is very much moderated by the proximity of the ocean
and he neither heats, nor takes any special care to control the temperature of
the plants. His approach to potting
would make must of us shudder. He
repots into moistened peat moss over a base of pebbles. (That's right, the stuff most of us
affectionately refer to as MUD). He emphasizes that during repotting, he only loosely fills the pot and
doesn't attempt to pack it down at all. He uses 3 1/2" square pots
that are 4 1/4" deep. He related an incident where he hired a college
student to do some of his repotting and the student carefully packed the pots
tight. He discovered the error when the plants all started to crump!
He waters with tap water which had a TDS reading of 100 and a pH of 8. We
visited slightly ahead of his main blooming season but the plants looked good
and many were in spike. (In
retrospect, we probably should have started in the North and made our way South
to artificially extend the blooming season but due to the fact that there were
limited times when we could hike the Milford Track, we had to start at the South
and work northward). Since most of his plants were not yet in flower, I emailed
him and asked if he could provide any pictures with the flowers open. He
did so and his photos in the following pictorial are marked with his name.
He does some hybridization with unifloras mainly and sends
the greenpods to Ron Maunder to sow in flasks. Unfortunately for me, the tags
were all marked with numbers and didn't tell either what the cross was or the
breeding history. As a result, the captions on some of the following
pictures don't help us much. He does have some really nice flowers that
would be useful for breeding stock though. In the pictures of the
individual flowers below, be sure and note the flat lateral sepals. This
is definitely something to breed for and he has a goodly number of plants like
that! I'm sitting here kicking myself for not getting any pollen but I
think the reason was that I wasn't sure of the parentage.

Super!

A view from his dining area. |
Two of his four hoop houses and a shade structure that
he also uses for growing plants. |
The other two hoop houses are more shaded. |

February.

This shows what the inside of a hoop house looks like
around the third week of February |
This shows the same hoop house on the 4th of
January. Note all the spikes that will bloom
about 6 weeks later. |

The photo to the left shows some of the detail of his
growing technique. Note that in NZ, they have a problem with
liverwort growing on the pot tops. In the US, I have a similar
problem with various mosses. |
A detail shot of one of his pots showing how compacted
the peat moss layer gets. The bottom half of the pot is filled
with washed pebbles. |
Some of the individual blooms. Note the flat LS. |
 |
To the left is a nicely colored flower that I believe
has a Veitchii background. The flower above was nicely presented
and had good color. |
 |
Four more blooms surround this caption. The
lower left is especially nicely colored and has very fine shape.
The LS's are more rounded and held very flat. Now if we only knew
what it was! |

This is one of the other demands upon Tudor's
time. A really nicely presented English Garden. Makes one
definitely consider the possibility of moving to New Zealand.

This concludes the visit to the Dunedin area. The whole
area is very scenic and you can see that Disas can be raised this far south as
long as there is some moderating influence on the weather.
