Watering rhythm
Every 3–5 days
The Coffee Plant is a striking houseplant native to Africa, known for producing coffee beans. It features deep green, glossy leaves and delicate white flowers with a lovely fragrance. It's wonderfully easy to grow indoors, with gentle, steady growth that makes it perfect for beginners. You can even enjoy harvesting your own coffee beans.
This plant loves bright, indirect light. Keep it away from direct sun and position it a short distance from your window for best results. Aim for temperatures between 15–25°C and humidity levels of 50–70%. During winter, make sure it stays above 10°C. Good air circulation is important too.
Light and temperature change a plant's metabolism, so the ideal cadence shifts with the seasons.
Spring
Every 2–4 days
Summer
Every 2–3 days
Autumn
Every 3–5 days
Winter
Every 5–7 days
Water when the top of the soil feels dry—check by inserting your finger about 2 cm into the soil. This plant is prone to root rot, so be cautious not to overwater. Always empty any water that collects in the saucer. The plant will appreciate regular misting on the leaves.
Quick lookup from symptom to likely cause and action.
| Symptom | Likely cause | What to try |
|---|---|---|
| Leaves turn yellow and drop | Usually caused by overwatering and root rot, or by prolonged exposure to temperatures that are too cold. | Cut back on watering and allow the soil to dry completely. Move the plant to a spot where it stays above 10°C. If root rot is advanced, consider repotting. |
| Leaves turn brown and wilt | The soil has dried out too much, or the temperature has dropped suddenly. | Water the plant if the soil is dry. Move it to a spot with more stable temperatures and mist the leaves regularly to raise humidity. |
| Pests appear (scale insects, spider mites, etc.) | Poor air circulation, insufficient humidity management, or lack of cleanliness. | Wipe affected areas with a damp cloth. If the problem spreads, consider using a horticultural insecticide. Mist the leaves daily and improve air circulation around the plant. |
| No flowers appear | The plant may be too young, receiving insufficient light, or lacking adequate nutrients. | If your plant is 3 years or older, move it to a brighter location. During the growing season (spring through autumn), feed with diluted fertilizer once or twice a month. |
| Leaves grow small | Insufficient light or inadequate nutrition. | Move the plant closer to a window where it receives brighter light. During the growing season, apply diluted liquid fertilizer about once a month. |
