Place the coffee seeds in a plastic container and soak them in 1 inch of water for a period of 24 hours.
Select the seeds that show a white protrusion on the side. The protrusion is the embryo beginning to emerge.
Fill a deep growing pot with lightweight, porous soil. A deep pot allows the taproot to grow unrestricted. Scrape a 1 1/2-inch-deep hole in the center of the soil.
Place a coffee seed in the hole. Cover the seed lightly with soil.
Water the seed daily, or as often as needed to keep the soil moist. Too much water, however, can cause the seed to rot. Drain the pot of any excess moisture.
Expect the seed to germinate in two to six months, depending on the condition of the seed. A fresh seed, from a recent crop, will require less time to germinate than an older seed. An older seed can take as long as six months to fully germinate.
