Care Guide | Coffee Plant (Coffea arabica)
Grow a house or patio plant that gives back: Coffea arabica is the world's most popular source of coffee beans. After a few years, you will have a plant that not only looks attractive but you can also proudly say that you grow your own coffee. It develops bright red “coffee cherries” packed with the beans you can then roast and brew. Not only is it a productive plant in the right conditions, but it also makes an attractive houseplant—even if you never harvest your own cup.
Characteristics
Coffee plants are evergreen, slow to moderate-growing shrubs or small trees that thrive in warm, humid environments. They prefer rich, well-drained soil and bright, indirect light. Typically growing 6–15 feet tall outdoors (but much smaller in containers), they feature glossy, dark green leaves and produce clusters of delicate, star-shaped white flowers. These are followed by green fruits that ripen to deep red. Coffea arabica is self-fertile, making it possible to produce fruit with just one plant.

Scientific Name
Coffea arabica belongs to the Rubiaceae family, which also includes gardenia and other flowering plants. It is the most widely cultivated coffee species, prized for its smooth, complex flavor compared to other species.
Classification
Coffee plants are woody evergreen perennials that can live for decades under proper care. They produce opposite pairs of glossy leaves and fragrant white flowers that bloom in clusters. The fruits, known as coffee cherries, contain two seeds—these seeds are the coffee beans used for brewing.
Origin
Coffea arabica originates from the highland forests of Ethiopia, where it grows under the canopy in cool, tropical conditions. It has been cultivated for centuries and spread across the world’s tropical regions, forming the backbone of global coffee production and culture.
USDA Hardiness Zones
Plants have a culture they prefer, just as people from various countries and households have their own customs and traditions. The U.S. Department of Agriculture created the USDA hardiness zone map to help gardeners identify the areas in which plants tend to grow well based on past average temperatures/climates. On the USDA's site, you can enter your zip code to identify your hardiness zone.
Coffee plants grow best in Zones 10–11, where temperatures remain consistently warm. They are sensitive to cold and should be protected from temperatures below 50°F (10°C). In cooler climates, they are commonly grown indoors as houseplants.
No fear if you live outside the hardiness zone—you can still grow coffee successfully indoors with proper light and humidity.
Height Potential
Outdoors, coffee plants can reach 6–15 feet tall, though they are often pruned shorter for easier harvesting. Indoors, they typically stay between 3–6 feet, making them manageable as a houseplant.
Planting
Plant coffee in rich, well-draining soil with plenty of organic matter. Choose a location with filtered light and protection from harsh sun and wind.
Coffee plants grow very well in containers, which allows for easy control of soil conditions and mobility. Ensure pots have good drainage and use slightly acidic soil.
Light
Coffea arabica prefers bright, indirect light similar to its natural understory habitat. Avoid direct, intense sunlight, which can scorch the leaves. Too little light may reduce growth and fruiting.
Soil/Watering
Keep soil consistently moist but not soggy. Coffee plants prefer slightly acidic soil (pH 6–6.5). Allow the top inch of soil to dry slightly between waterings, but do not let the plant dry out completely.
Higher humidity levels will improve plant health and growth.
Fertilizer
Feed regularly during the growing season (spring through early fall) with a balanced fertilizer or one formulated for acid-loving plants. Reduce feeding during winter when growth slows.
Pruning
Prune to control height and encourage bushier growth. Removing the top growth can help the plant branch out, making it fuller and more productive. Also remove any dead or weak growth.
Cold Weather Care
Coffee plants are sensitive to cold and should be kept above 50°F (10°C). Protect from drafts and sudden temperature changes. Bring outdoor plants inside when temperatures drop. Learn more in our Overwintering Guide.
Fruiting and Harvesting
Coffee plants typically begin producing fruit in 3–5 years under good conditions. The cherries ripen from green to bright red and should be harvested when fully ripe.
Each cherry contains two beans that must be processed, dried, and roasted before use. While growing your own coffee is rewarding, processing the beans requires time and effort.
Common Pests
Coffee plants may attract spider mites, aphids, and scale insects, especially indoors. Regular inspection and treatment with neem oil or insecticidal soap can help keep pests under control.
Toxic to Pets?
Coffea arabica is toxic to pets if ingested, particularly the leaves and unripe berries, as they contain caffeine-related compounds. Keep out of reach of cats and dogs.
After Arrival Care
Please give your plant a little TLC after its journey through the mail 📬. Here are a few steps we recommend:
- Unwrap immediately to provide fresh air to the plant and soil.
- Wait a few days before exposing to full sunlight so your plant can adjust after being in a dark box for several days.
- Always protect from heat and cold because temperature extremes can be stressful or deadly for plants.
- Water. Your baby plant may be parched and even a little wilted but thorough hydration will help it recover.
- Grow out in a larger pot to increase your chances of success—i.e., a quarter gallon—Then transplant to the ground or the next pot size up once the roots fill to the bottom. This will help the plant get sufficient water and nutrients directly to the roots.

Repotting
We highly recommend growing your baby plant out in a larger pot 🪴 to increase your chances of success
You don’t have to repot immediately, but the sooner you do, the more room it has to grow.
Here are some general repotting tips:
- Start with a pot that's 1-2 inches larger in diameter than the starter-sized pot it came in. A pint or quart would be great.
- Transplant to the next pot size up once the roots fill to the bottom.
