Coffee plant (Coffea arabica): care, flowering and coffee cherries indoors

To care for an indoor coffee plant, place it in bright but filtered light from an east- or west-facing window, keep it above 15°C all year round, water generously from spring to autumn without waterlogging the growing medium, and surround it with moderate to high humidity. This small tree with glossy foliage is Coffea arabica, the species that produces arabica coffee.

It is first chosen for its foliage, but a well-established plant will eventually produce jasmine-scented white flowers, followed by real coffee cherries. This guide brings together proven guidelines from botanical gardens and universities, and practical steps to prevent brown, black, or falling leaves.

🌿 Why choose a coffee plant for your home

The coffee plant combines three pleasures rarely found in a single houseplant: highly decorative evergreen foliage, fragrant flowers, and fruit.

Arranged in opposite pairs according to the RHS, its dark green, glossy leaves with wavy edges measure 10 to 20 cm, according to the University of Florida Institute of Food and Agricultural Sciences (UF IFAS) fact sheet, which recommends it as a houseplant if kept at a modest size, in bright indirect light, and in a humid environment.

It grows slowly, takes well to pruning, and tells a story: it is the plant from your morning cup, rarely seen anywhere but in tropical greenhouses.

🔎 The coffee plant's ID card

According to Plants of the World Online (POWO) from the Royal Botanic Gardens, Kew, the accepted name is Coffea arabica L., from the Rubiaceae family, a shrub or small tree native to eastern South Sudan, southwestern Ethiopia, and northern Kenya, in a tropical biome with a pronounced dry season. The Muséum national d'Histoire naturelle (MNHN) specifies that it can reach 9 to 12 m in nature and that its leaves, about ten centimetres long, are evergreen and elliptical.

In a pot, growth remains much more restrained: the North Carolina State University Extension (NC State Extension) indicates that indoor plants are generally kept between approximately 1.2 and 1.8 m (4 to 6 feet).

📋 Quick fact sheet

The essential growing guidelines, all at a glance.

📍 Where to place a coffee plant and what light it needs

Place your coffee plant near an east- or west-facing window: the RHS (Royal Horticultural Society) recommends these orientations and a partial shade position, as it is a woodland plant in nature. UF IFAS Gardening Solutions also reminds us that it grows naturally under cover and is planted in light shade.

A south window is suitable behind a sheer curtain; however, the midday sun through the glass leaves dry brown patches on the leaves. The same RHS source advises protecting it from drafts: keep it away from entrance doors, open windows in winter, and radiators.

☀️ Ideal: East- or west-facing window, or south window with a sheer curtain, slightly set back from the glass

🌥️ Acceptable: Bright room without direct sun: slower growth, less frequent flowering

🚫 Avoid: Midday sun through the glass, cold drafts, radiators, dark corners

🪴 Repotting a coffee plant: acidic growing medium and method

To repot a coffee plant, choose a rich, well-draining potting mix: the RHS advises, under cover, a peat-free soil-based mix enriched with organic matter, and placing the plant in acidic to neutral soil.

The University of Florida fact sheet also classifies it among plants for acidic soil, kept regularly moist. The RHS recommends repotting every 2 to 3 years in spring, in a pot with drainage holes just slightly larger than the previous one, so that the root ball does not remain waterlogged.

✂️ Coffee plant care: watering, fertiliser, and humidity

Coffee plant care follows a simple routine given by the RHS: water generously during the growing season, apply a balanced liquid fertiliser every 2 weeks, then water moderately in winter.

The growing medium should remain moist but never waterlogged: NC State Extension speaks of soil that is regularly moist but not saturated, and UF IFAS lists root rot from overwatering among common problems.

Regarding air, the RHS requires moderate to high humidity: place the pot on a tray of damp clay pebbles, without soaking the bottom, and group it with other plants rather than misting it.

💧 Watering: Water thoroughly when the surface of the growing medium begins to dry, empty the saucer

💧 Water: Low-calcium water, such as rainwater, better suits an acidic soil

🌱 Fertiliser: Balanced liquid fertiliser every 2 weeks from spring to the end of summer

💧 Humidity: Damp pebble tray and grouping of plants, especially near heating

🧹 Cleaning: Wipe the leaves to remove dust and spot pests early

🍂 Making a coffee plant flower and fruit through the seasons

To make a coffee plant fruit, you need above all patience and light: the RHS indicates that flowers appear once the plant is about 4 years old, and NC State Extension places flowering 3 to 4 years after planting, from late spring to early summer.

The white, star-shaped flowers scented with jasmine emerge from the leaf axils. Good news: arabica flowers are self-fertile according to UF IFAS Gardening Solutions, unlike robusta flowers which require cross-pollination; a single plant is therefore enough. The green fruits then ripen over several months, passing through yellow then deep red, according to NC State Extension.

Each cherry contains two beans, and the RHS estimates that under ideal conditions you can harvest enough for a homemade cup of coffee: a symbolic pleasure rather than a production. In winter, keep the plant warm, space out watering, and stop fertilising.

🌱 Propagating a coffee plant: sowing fresh seeds

The RHS indicates a single method for propagating the coffee plant: sowing fresh seeds, warning that germination can be irregular. If your plant has produced deep red cherries, harvest them, remove the pulp, and sow the seeds quickly, without letting them dry, in a light mix kept just moist, warm, and in light without direct sun.

Stem cuttings are sometimes mentioned, but none of the authoritative sources we have consulted describe them: we prefer not to promise you results. Finally, a young coffee plant is sometimes found as a small terrarium plant; it stays there as long as it is small, before moving to a real pot.

To find out which species thrive there long-term, consult our guide to plants for terrariums.

🐛 Common problems: causes and solutions

Coffee plant leaves that turn brown, black, or fall off almost always indicate a deviation in humidity, heat, or watering. NC State Extension notes leaf drop below 55°F, or around 13°C, and UF IFAS lists root rot from overwatering and mineral deficiencies.

Regarding pests, the RHS mentions the greenhouse spider mite; NC State Extension adds mealybugs, woolly aphids, thrips, and caterpillars.

🎨 What plants to pair with your coffee plant

The coffee plant gets along well with indoor plants that, like it, love filtered light, warmth, and slightly humid air. The Ficus ginseng shares its love for a bright, stable spot, the Schefflera adds contrasting palm-like foliage, and the Spathiphyllum adds its white flowers to the base of the group.

Grouped together, these plants create a more humid microclimate that benefits each of them. To create this green corner, browse our indoor plants, our bathroom plants, or our rare plants.

⚠️ Is the coffee plant toxic to cats and dogs?

To be safe, yes: the ASPCA (American Society for the Prevention of Cruelty to Animals) classifies coffee and caffeine as foods that should never be given to animals, as they contain methylxanthines that can cause vomiting, diarrhea, panting, thirst, excessive urination, hyperactivity, heart rhythm disorders, tremors, seizures, and even death.

However, the seeds contained in the cherries are precisely coffee beans, and the MNHN reminds us that arabica contains caffeine, less than robusta. The coffee plant itself is not listed in the ASPCA plant database: its "Coffee Tree" page refers to another plant, Polyscias guilfoylei.

We have not found any authoritative source quantifying the risk associated with the leaves: keep the plant out of reach of animals and pick up fallen cherries. If your cat likes to nibble on foliage, choose its neighbors from our list of non-toxic plants for cats.

✅ Our expert tips for success

A successful coffee plant depends on four rules: bright but filtered light, a stable temperature above 15°C, generous watering during growth without ever waterlogging, and ambient humidity enhanced by a tray of wet pebbles.

Add a balanced fertilizer every 2 weeks in spring and summer, repot every 2 to 3 years, and give it time: it is around 4 years that it rewards your patience with its fragrant flowers. If the leaves turn brown or fall, first check the temperature, drafts, and substrate moisture.
