Making the Right
by George Yasuda
George Yasuda and his
orchard in Kona Hawaii.
There are proven, basic techniques in growing high
quality, high production Kona coffee trees.
Volcanic, good drainage loam seems to be best suited
for coffee trees. Crushed coral and magnesium oxide
needs to be added to the soil approximately every 3-4
years. Nitrogen, phosphorous and potassium are needed
in the right proportions as well. These elements also
need to come from the correct sources. Coffee does not
respond favorably to fertilizers with chlorine and too
much molybdenum and boron will have unfavorable affects
on the coffee. Iron and zinc are important for coffee
but be careful of the sources too. Chelated iron and
chelated zinc are very good sources fed through fertigation.
The genetics of the coffee stock is also very important.
Seeds dervied from parent plants that have poor taste,
poor clustering, leaf bronzing, weak root structuring
will produce less desirable stock. Its important
to have seeds obtained from productive, healthy, good
tasting, strong root structured trees to assure orchards
that flourish for many decades, even over a century.
Good, consistent maintenance is valuable. Over use
of pesticides, misapplication of pesticides such as
overdrifting is costly to plants and people.
Keeping the tree healthy prevents overusage of pesticides.
So called coffee professionals were saying back in 1998
that Kona coffee would be destroyed within 7 years due
to an epidemic of root knot nematodes. That of course
was a hoax. Well maintained coffee trees obtained from
good proven stock are thriving well today and have been
for many decades.
This box of coffee seedlings
raised by Tiare Lani is enough for 1000 trees!
There are several other factors in producing high quality,
productive Kona coffee orchards but one of the most
prominent is not to cut corners in the installation
and care of the trees. It is a fact that quality coffee
can only be produced and enhanced in proper orchard
installation and care. So why cut corners in the field
with a remarkable plant that will produce world famous
Kona coffee for over a century?
