Growing Coffee Trees in South Korea: A 3-Year Journey of Survival and Harvest

From Survival to Harvest: Mastering Coffee Cultivation in a Four-Season Climate

Can coffee trees survive the freezing winters of inland South Korea? My journey began in November 2022 at a warm coffee farm in Gyeongbuk. Since then, I have moved these trees to our new home, Greenfingers Farm, facing harsh winters and celebrating successful harvests. Here is the reality of growing coffee in a non-tropical climate.

1. The Beginning: From Gyeongbuk to Greenfingers Farm

In late 2022, I first encountered lush coffee trees in Gyeongbuk, where the climate is relatively mild. Inspired, I brought small, 1-meter-tall coffee trees to our farm. To help them grow, I moved them to the sunniest spots and even participated in local festivals with fruiting trees.

The Challenge of Relocation

In May 2024, as we moved to a larger facility at Greenfingers, the coffee trees migrated with us. We planted them directly into the ground, dreaming of a vast "Coffee Tree Fortress." Although they looked small compared to the vast greenhouse, our goal was to create an immersive experience forest for visitors.

2. Surviving the Harsh Inland Winter

Temperature: The Life or Death Factor

Coffee trees thrive between 18°C and 25°C (64°F–77°F). While Gyeongbuk was mild, our inland location faced a brutal winter. Even with greenhouse heating set to a minimum of 10°C, the cold was unforgiving.

Survival Tactics of the Coffee Tree

To survive, the trees shed almost all their leaves, leaving behind bare branches like thorns. It was a heartbreaking sight, but a necessary sacrifice for the tree to preserve its core life. Thankfully, they have recovered through the spring and summer, showing incredible resilience.

3. From Blossom to Bean: The Korean Coffee Cycle

In their native habitats, coffee trees bloom based on the hemisphere. However, in South Korea’s four-season climate, the cycle adjusts based on photosynthesis and light exposure.

Our 3-Year Observation Record

• June – August: White blossoms appear and fade. 
• September – November: Green cherries begin to form. 
• November – May: Cherries slowly ripen into a deep red.

Cultivation Tips: Sun, Heat, and Wind

Beyond temperature, sunlight is crucial for the cherries to turn from green to red. Additionally, wind (airflow) is vital. Coffee trees naturally grow at altitudes above 800m with constant breezes. Without proper airflow, they become highly vulnerable to pests like Mealybugs

4. Propagation: Growing New Life from Seed

When you peel a ripe red coffee cherry, you find the seeds we know as coffee beans.

• Sowing: Plant the seeds in potting soil.
• Germination: Due to their size, it takes about a full month for sprouts to appear.
• Growth: The first leaves look like small cabbages (cotyledons), followed by the glossy, true leaves of the coffee tree.

Tip: It takes about 3 years of growth from a seedling to see your first harvest.

Final Thoughts: To the Migrant Coffee Trees

While open-field cultivation is impossible in Korea, the rise of Smart Farms gives me hope for the future of Korean coffee. For now, they are beloved as ornamental foliage (like Monstera) in many homes. Cheers to the "Migrant Coffee Trees" that endured the bitter cold and scorching heat to bring us a touch of the tropics! ☕
