Everything it needs
9 essentials at a glance
Watering
Coffea Arabica prefers consistently moist soil, so water when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, using enough to saturate the root ball. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and wilting.
Light
Coffea Arabica thrives in bright, indirect light but can tolerate partial shade.
Ideally, it should receive 4-6 hours of filtered sunlight daily. Avoid direct sunlight, as it can scorch the leaves. If grown indoors, place near a window with sheer curtains to diffuse the light.
Soil
The ideal soil for Coffea Arabica is well-draining, rich in organic matter, with a pH range of 6.0 to 6.5.
A recommended potting mix includes equal parts peat moss, pine bark, and perlite to ensure good drainage and aeration.
Humidity
Coffea Arabica prefers high humidity levels, ideally between 40-60%.
To increase humidity, consider using a humidifier, placing a tray of water near the plant, or misting the leaves regularly. Signs of humidity stress include browning leaf tips and edges.
Temperature
Coffea Arabica thrives in temperatures between 60-75°F (15-24°C) and is hardy in zones 10-11.
It does not tolerate frost and should be protected from temperatures below 50°F (10°C). During the growing season, maintain a warm environment, while cooler temperatures in winter can help promote dormancy.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10 or 20-20-20 every 4-6 weeks during the growing season.
Reduce feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves (nitrogen), poor growth (phosphorus), and leaf drop (potassium).
Pruning
Prune Coffea Arabica in early spring to maintain its shape and encourage bushier growth.
Use clean, sharp pruning shears to remove any dead or damaged branches. Regularly remove spent flowers to promote new growth and prevent disease.
Repotting
Repot Coffea Arabica every 1-2 years or when it becomes root-bound, indicated by roots growing out of the drainage holes.
Choose a pot 1-2 inches larger in diameter. Carefully remove the plant from its current pot, loosen any tightly bound roots, and place it in fresh potting mix, ensuring the root ball is at the same depth as before.
Propagation
Coffea Arabica can be propagated through seeds or cuttings.
For seed propagation, soak seeds in water for 24 hours, then plant them in a moist potting mix. Keep the soil warm and humid until germination, which can take 2-3 months. For cuttings, take 4-6 inch stem cuttings in spring, dip in rooting hormone, and plant in a well-draining mix, keeping them humid until roots develop.
When it's unhappy
Yellow leaves
Why it happens
Often caused by over-watering or nutrient deficiency.
How to fix it
Check soil moisture and adjust watering schedule. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Leaf drop
Why it happens
Can result from sudden temperature changes or under-watering.
How to fix it
Maintain consistent temperatures and water when the top inch of soil is dry.
Brown leaf tips
Why it happens
Typically a sign of low humidity or over-fertilization.
How to fix it
Increase humidity around the plant and reduce fertilizer application.
Pests (e.g., spider mites, aphids)
Why it happens
Pests thrive in dry conditions and can infest the plant.
How to fix it
Regularly inspect the plant, and treat infestations with insecticidal soap or neem oil.
Root rot
Why it happens
Caused by over-watering and poorly draining soil.
How to fix it
Ensure proper drainage and allow the soil to dry out between waterings.
Care through the year
Spring
In spring, increase watering as the plant enters its active growth phase. Fertilize every 4-6 weeks and prune any dead or damaged branches.
Summer
During summer, ensure the plant receives enough light and humidity. Water regularly, and monitor for pests, as they can thrive in warm conditions.
Fall
In fall, gradually reduce watering as the plant prepares for dormancy. Continue to fertilize until late fall, and check for any signs of stress.
Winter
In winter, reduce watering to every 2-3 weeks and keep the plant in a warm area away from drafts. Maintain humidity levels to prevent leaf drop.
Toxicity & Safety
Coffea Arabica is non-toxic to pets and children. However, ingestion of large quantities of coffee beans may cause mild gastrointestinal upset in pets.
