Soak the coffee seeds in a bowl of tepid water. Allow the seeds to soak for 24 hours. The coffee beans with an embryo inside emerge showing it is a live or viable seed.
Fill a 4-inch pot with well-draining potting soil.
Form a hole with a pencil’s blunt end. Place the coffee bean seeds carefully in the pot’s center and push the coffee bean into the soil to a depth of 1 1/2 inches. Have the embryo facing upward in the soil.
Water the soil thoroughly. Allow the water to run out of the drainage holes.
Place the pots in a tray and position the tray in a bright window, out of direct sunlight.
Check the soil daily for moisture. Water the soil, keeping it moist but not soggy. It takes one to three months for the seeds to germinate.
Move the pots to a bright location when the seedlings have three sets of leaves. The temperature should remain 70 to 80 degrees Fahrenheit. In the winter, do not allow the air temperature to go below 50 F.
Feel the soil twice a week for moisture. Add water when the soil is dry. Lightly mist the foliage once a day.
Feed the miniature coffee tree with an orchid fertilizer during the active growing months. Mix and apply according to label directions.
