How to Grow Hawaiian Coffee

Soak the coffee beans. Fill a pan or shallow dish with water. Immerse the Hawaiian, or Kona, coffee beans in the water. Keep them in the water for at least 24 hours.

Add potting soil. Select a planter at least 1 foot deep and wide. Fill the pot with potting soil.

Dig a 1-inch deep hole in the potting soil with your fingers or a small garden spade. Plant the seeds. Leave the skin on the bean. Expose the round head of the bean partially above the soil. This lets the bean receive light and fresh air.

Water the plants daily. Be careful not to overwater: leave the soil moist, but well-drained in the pot.

Transplant the seedlings after three to six weeks. Check for three sets of leaves growing from a central green stalk. When you notice all three sets of leaves, move each seedling into an individual pot at least 1 foot deep and wide. Center each sprouting bean in the potting soil.

Maintain a healthy temperature. To mimic an authentic Hawaiian climate, set your home or greenhouse temperature between 65 and 85 degrees Fahrenheit. For outdoor plants growing in a warm climate, place the planter in an area of the yard or porch that receives direct morning sunshine and cool afternoon shade.
