How to Grow Coffee Plants?

Coffee is one of the most popular beverages in the world, with millions of people enjoying its rich flavor and stimulating effects daily. But did you know that you can grow your own coffee plants at home? In this comprehensive guide, we’ll explore the process of growing coffee plants, from selecting the right variety to harvesting your own beans. Let’s dive in!

Introduction to Coffee Plants

Coffee plants (Coffea spp.) are small, evergreen trees or shrubs native to tropical regions of Africa. There are over 120 species of Coffea, but the two main species cultivated for their beans are Coffea arabica (Arabica coffee) and Coffea canephora (Robusta coffee). Arabica is known for its superior flavor and lower caffeine content, while Robusta is more disease-resistant and has a higher caffeine content.

Coffee plants produce small, fragrant white flowers that develop into green, red, or purple fruit called cherries. Each cherry contains two seeds, which are the coffee beans. To grow coffee plants at home, you’ll need to recreate the tropical conditions they naturally thrive in, which includes providing adequate warmth, humidity, and sunlight.

Choosing the Right Coffee Plant Variety

When selecting a coffee plant variety to grow at home, consider the following factors:


If you’re growing coffee plants primarily for their beans, choose a variety known for its desirable flavor. Arabica is generally considered to have a better taste, with a more complex and nuanced flavor profile than Robusta.

Growing conditions

Consider the specific growing conditions of your home or garden. If you live in an area with a warmer, more humid climate, you may have success growing Robusta, which is more tolerant of heat and humidity. Arabica, on the other hand, prefers cooler temperatures and higher elevations.

Disease resistance

If you’re concerned about diseases affecting your coffee plants, Robusta may be a better choice, as it’s more resistant to common coffee plant diseases, such as coffee leaf rust and coffee berry disease.

Obtaining Coffee Plant Seeds or Seedlings

To start growing coffee plants, you’ll need to obtain seeds or seedlings. Here’s how:


Purchase fresh coffee seeds (beans) from a reputable supplier. Look for seeds that have been recently harvested, as older seeds may not germinate well. Ensure that the seeds have not been roasted or processed in any way, as this will render them unsuitable for germination.


If you prefer to start with seedlings, you can purchase young coffee plants from a nursery or online supplier. Look for healthy, well-established plants with a strong root system.

Germinating Coffee Seeds

If you’re starting with coffee seeds, follow these steps to germinate them:

Soak the seeds

Soak your coffee seeds in water for 24 hours to help soften the outer shell and promote germination.

Prepare the growing medium

Fill a seed tray or small pots with a well-draining, sterile seed-starting mix. You can also use a mixture of equal parts peat moss, perlite, and vermiculite.

Plant the seeds

Sow the soaked coffee seeds about 1/2 inch deep in the growing medium, and cover them lightly with additional soil.

Provide warmth and moisture

Place the seed tray or pots in a warm location, ideally with a temperature between 70-75°F (21-24°C). Keep the growing medium consistently moist but not waterlogged.

Wait for germination

Coffee seeds can take anywhere from 2-6 weeks to germinate. Be patient, and continue to provide warmth and moisture during this time.

Growing Coffee Plants: Light, Temperature, and Humidity

Once your coffee seeds have germinated or you’ve obtained seedlings, it’s time to focus on providing the right growing conditions. Here’s what you need to know:


Coffee plants prefer bright, indirect light. Place your plants near a south or east-facing window, or provide supplemental lighting with a grow light if needed. Avoid direct sunlight, as this can scorch the leaves.


Coffee plants thrive in temperatures between 60-70°F (15-24°C) during the day and 50-60°F (10-15°C) at night. Avoid exposing your plants to temperatures below 45°F (7°C), as this can cause damage or stunt their growth.


Coffee plants require high humidity levels, ideally around 60-70%. To maintain humidity, place a tray filled with water and pebbles beneath your plants, or use a humidifier. You can also mist your plants with water regularly.

Soil and Fertilization for Coffee Plants

To ensure healthy growth, coffee plants need well-draining, slightly acidic soil with a pH between 6.0-6.5. You can use a commercial potting mix designed for acid-loving plants, or create your own by combining equal parts peat moss, perlite, and vermiculite.

Fertilize your coffee plants every 2-3 months with a balanced, slow-release fertilizer, following the package instructions for application rates. Alternatively, you can use a liquid fertilizer at half strength every 2-4 weeks during the growing season.

Watering and Pruning Coffee Plants

Proper watering and pruning are essential for maintaining the health and productivity of your coffee plants. Here’s what you need to know:


Water your coffee plants when the top inch of soil feels dry to the touch. Provide enough water to thoroughly moisten the soil, but avoid overwatering, as this can lead to root rot. Coffee plants prefer consistent moisture, so it’s important not to let the soil dry out completely.


Prune your coffee plants to maintain their shape and encourage bushier growth. Remove any dead, damaged, or crossing branches, and trim back the main stem to promote branching. You can also pinch back the growing tips of young plants to encourage a more compact, bushy form.

Flowering and Fruit Development

Under the right conditions, coffee plants will begin to produce fragrant, white flowers after 3-4 years. These flowers will eventually develop into green cherries, which will ripen to a red or purple color over the course of several months.

To encourage flowering and fruit development, you can:

Provide a period of cooler temperatures

Expose your coffee plants to slightly cooler temperatures (around 55-60°F or 13-16°C) for a few weeks during the winter months. This can help stimulate flower bud formation.

Ensure adequate light

Make sure your plants are receiving enough bright, indirect light throughout the year.

Maintain proper care

Continue to provide consistent watering, fertilization, and humidity to support your plants’ overall health.

Harvesting and Processing Coffee Beans

Once the cherries on your coffee plants have ripened to a deep red or purple color, it’s time to harvest your coffee beans. Here’s how:

Harvest the cherries

Gently pick the ripe cherries from your plants, being careful not to damage the branches.

Remove the beans

To extract the beans, you can either use a depulping machine or squeeze the cherries by hand to remove the outer flesh. You should be left with two coffee beans encased in a thin, parchment-like covering.

Ferment and wash the beans

Place the beans in a container with water and let them ferment for 24-48 hours. This will help break down the remaining fruit and mucilage. After fermentation, wash the beans thoroughly to remove any remaining debris.

Dry the beans

Spread the beans out in a thin layer on a mesh screen or drying rack, and allow them to dry in a well-ventilated area for several days. The beans should feel hard and dry to the touch when they’re ready.

Remove the parchment layer

Once the beans are dry, use your hands or a machine to remove the parchment-like covering from each bean.

Store or roast the beans

You can now store your green coffee beans in a cool, dry place, or roast them to your desired level of darkness using a coffee roaster or a stovetop method.


In conclusion, growing coffee plants at home can be a rewarding and enjoyable endeavor. By following the steps outlined in this comprehensive guide, you’ll be well on your way to cultivating your own coffee plants and enjoying the fruits of your labor. Happy growing!
