Plant 30cm tall in 10cm pot Height: Up to 6 ft (1.8 m) indoors, confined to a pot. You can prune your plant back harshly in spring to keep it at the desired size. Light: Keep in bright light, shaded from direct sun. Water: Keep soil thoroughly moist in spring and summer, barely moist in fall and winter. Always use tepid water for watering your houseplants. Humidity: Requires moist air (around 50% relative humidity or higher). Use a cool-mist room humidifier for best results. Temperature: Average room (65-75°F/18-24°C). Coffea arabica can withstand cooler temperatures in fall and winter, when growth slows down, but it's not tolerant of freezing temperatures. Soil: Peat moss based potting mix with horticultural sand added to provide good drainage. Fertilizer: Feed every 2 weeks spring and summer with a balanced water-soluble fertilizer diluted by half. Propagation: Sow fresh seeds in spring. Cuttings are difficult to propagate, but you'll have the best chance at success by taking young stems before they have hardened.
