Jack McKinlayThe
final Disa grower we visited in New Zealand had to have some of the most
impressive Disas we saw in NZ. His
name is Jack McKinlay and since his only interest is Disas, he never got
side-tracked like some of us by trying to accommodate a variety of different
growing conditions for a bunch of different orchids.
His plants were the biggest I have ever seen. One picture that I took at
his place shows a leaf from one of his plants completely dwarfing a 12 inch
ruler and you will find that picture further down this page. Of course, Jack, in his usual modest way, attributes
a great deal of his success to his original stock bred by Issy Klein of
Melbourne, Australia. I was disappointed that it was so late in the season as
he had very few plants left in bloom.
His market is the cut flower trade as well as the sale of some pot
plants, and most are sold over the Christmas holidays. He did have some flowers
saved that he was breeding on from, and there was quite a variety. One of the
better ones was a nice yellow Riette. He has succeeded in producing a nice
yellow with a standard sized flower. He hasn't done a lot of breeding yet but I
was really impressed with what he has done. He is actively pursuing a nice
big yellow which will be used as both a cut flower and as a pot plant and has
succeeded remarkably well. His culture method was similar to others
that I had seen in NZ in that he was using only the reconstituted Sphagnum moss
as a medium and was also only bottom watering.
As with the other NZ growers, after the pellets are reconstituted, he fluffs the
moss up by mixing with a paint mixer. He pots very loosely in 12cm square
pots that are 14 cm deep. It's interesting to note that he only uses terracotta
colored pots which he feels keeps the temperature down. He attempts
to have all his plants repotted by June ( If you live in the northern
hemisphere, think December) as he feels that he gets more vigor in the following
years crop that way. I think
the key to the whole culture problem is the bottom watering, as it prevents any
compression of the surface layer and subsequent liverwort or moss buildup at the
surface, which interferes with the air to the roots.
Another thing that was noticeable about his growing setup was the
absolutely ideal location. His
growing area is situated on a high ridge where there is constant air movement,
and where you can see the ocean to the west and is also very close to the
eastern ocean.
He waters mostly with rainwater except for some trucked in water when
there is insufficient rain and grows his plants in very bright light. He
fertilizes once a month at 200 ppm TDS for 10 months a year, choosing to skip
the two coldest months. To fertilize, he floods his trays and lets sit for a
while, then drains the fertilizer mix and resumes watering with rain
water. He normally floods and then drains but during the winter, he floods
continuously as he feels that it more closely approaches nature that
way. There are no trees around to cut down on light and he only uses minimal
shadecloth covering on the roof during the summer.
The temperature range is ideal. It
never gets down to freezing in the winter and, while the sun gets really hot in
the summer, the cooling breeze from the ocean probably limits the maximum
temperature at the plants to about the low 80's in Fahrenheit degrees.
I was unaware until I visited New Zealand that the local Maori name for
NZ is "the land of the long white cloud".
This frequent cloud covering also helps to cool the plants during the
day. I don't think I have ever seen
a location that is more ideally situated for growing Disas.
That's about all that I have on Jack's place. Although he has his unique brand of culture, it clearly works for him. Now if we could only get some of his plants back to the States! | ||||||||||||||||||||||||||||||||||||
