The Basic Needs
of a Kona Coffee Tree
by George Yasuda
Examples of coffee trees
with good nutrition (foreground) and poor nutrition
(background). Good nutrition will increase yields
dramatically. George Yasuda (standing on the left)
is well known for his wealth of knowledge in raising
world class Kona coffee orchards.
Each living organism has basic requirements to perform
optimally. On numerous occasions I have been asked this
question, where can we grow Kona coffee trees
viably? Here are some basic answers:
1. Rainfall should be close to 6 to 8 inches per month.
2. Sun light should be about 45,000 to 50,000 foot candles
3. Volcanic soil with a slightly high PH and good drainage
4. Growing temperatures should be between 74½
to 90½ Fahrenheit.
5. An orchard should be in an area protected from winds
that exceed 25mph.
6. In Kona the optimum elevation is between 500 to 2,300
7. A good fertilizer program is very important. Adding
too little or too much of any one particular nutrient
can be very harmful.
8. Correct maintenance is also very important. Herbiciding
too heavily can hurt the trees.
9. Supplemental irrigation can be very beneficial. Water
should be low in salinity.
10. Micronutrient supplementation can also be very beneficial.
Trees can become poor performers if lacking just one
nutrient even if the other nutrients are in abundant
