Coffea arabica 'Caturra'
1. Introduction & Taxonomy
Coffea arabica 'Caturra' is a compact, naturally mutated form of Bourbon coffee discovered in Brazil in the early 20th century. This variety revolutionized coffee cultivation by offering the exceptional cup quality of Bourbon in a more manageable, dwarf form that allowed high-density planting. Caturra became foundational to Latin American coffee production and served as a parent for numerous important modern varieties, earning its place as one of the most influential coffee cultivars in history. Coffea arabica 'Caturra' is notable for growing to just 30 cm tall.
Caturra or Cattura is a dwarf coffee variety that is said to have been discovered in a plantation in Brazil. It was popular in Central and South America for its modest size to less than 2 m tall and its tolerance of full sun. Plants generally start flowering when only 30 cm tall. Coffea arabica 'Obata' and other dwarf varieties with better disease resistance are now largely replacing Caturra in commercial plantations. The coffee plant is originally native to the humid montane forests of Ethiopia and South Sudan between 1300 and 1900 m elevation, but today it is cultivated in many other parts of the world.

Seasonal Care Calendar
Follow this season-by-season guide for optimal care timing throughout the year.
🌱 Spring (March–May)
Primary flowering season. Apply balanced fertilizer emphasizing nitrogen and potassium to support abundant bloom and fruit set. Increase irrigation as temperatures rise. Begin preventive fungicide program for leaf rust in susceptible areas. Monitor closely for pest emergence.
☀️ Summer (June–August)
Berry development and maturation with high nutritional and water demands. Maintain consistent fertilization and irrigation schedules. Caturra's heavy fruit load requires adequate support through nutrition. Continue rust monitoring and treatment. Provide shade management to prevent berry scorching in hot climates.
🍂 Fall (September–November)
Main harvest season as berries ripen to bright red. Caturra's compact size facilitates hand harvesting. Implement thorough harvest sanitation, removing all berries to reduce berry borer pressure. Begin reducing fertilization post-harvest. Evaluate plant health and disease impact.
❄️ Winter (December–February)
Post-harvest recovery period with reduced growth. Minimal fertilization needed. Reduce irrigation while maintaining adequate soil moisture. Prime time for renovation pruning to rejuvenate aging plants or open dense canopies. Plan next season's disease management strategy based on previous year's experience.
5. Diseases & Pests
Coffea arabica 'Caturra' is generally robust and pest-resistant when cultural conditions are optimal.
Major Diseases
Root Rot (Phytophthora, Pythium)
Caused by overwatering or poor drainage. Ensure good drainage and avoid waterlogging. Improve soil aeration.
Powdery Mildew
White powdery coating on leaves. Improve air circulation, avoid overhead watering, and apply fungicide if severe.
Leaf Spot (various fungi)
Brown or black spots on foliage. Remove affected leaves, improve airflow, and avoid wetting foliage.
Common Pests
- Scale Insects — Hard or soft scales on stems and leaves; treat with horticultural oil
- Spider Mites — Fine webbing on undersides of leaves in dry conditions; increase humidity
- Mealybugs — White cottony masses at leaf axils; spray with soapy water or neem oil
- Aphids — Cluster on new growth; spray with soapy water or introduce ladybirds
- Whiteflies — Tiny white insects on leaf undersides; use yellow sticky traps
IPM: (1) Choose the right species for your conditions. (2) Maintain good air circulation and hygiene. (3) Monitor regularly and act early. (4) Use chemical controls only as a last resort.
6. Indoor & Container Growing
Coffea arabica 'Caturra' can be grown in containers and brought indoors during winter in cold climates.
Container Selection

Frequently Asked Questions
Why is Caturra less common than it used to be?
Caturra's high susceptibility to coffee leaf rust has dramatically reduced cultivation following severe rust epidemics in Latin America starting around 2008-2012. Many farmers replaced Caturra with rust-resistant varieties like Castillo or F1 hybrids to avoid crop losses and reduce fungicide costs. However, Caturra remains important in specialty coffee due to its excellent cup quality, and some farmers maintain it in lower-risk areas or with intensive disease management.
How does Caturra's quality compare to Bourbon?
Caturra inherited Bourbon's excellent cup quality characteristics, including complexity, sweetness, and balanced acidity, making it a favorite in specialty coffee. Most professional cuppers cannot reliably distinguish well-grown Caturra from Bourbon. The compact size and increased productivity made quality coffee more accessible without quality compromise, a major advantage over Bourbon.
Can Caturra be grown organically?
Organic Caturra cultivation is extremely challenging due to high rust susceptibility without synthetic fungicides. Success requires optimal conditions: sufficient altitude (above 1400m where cooler temperatures slow rust), strategic shade management, copper-based organic fungicides, wide spacing for air circulation, and meticulous sanitation. Even with intensive management, organic yields are typically 30-50% lower than conventional, requiring premium prices to be economically viable.
Is Caturra suitable for home growing?
Yes, Caturra's compact size makes it excellent for container cultivation and home growing. It produces attractive foliage, fragrant flowers, and decorative red berries. For hobby growers, disease pressure is less critical than for commercial production. Provide bright indirect light, consistent moisture, and temperatures above 13°C. A single plant can produce several hundred beans annually, enough for occasional home roasting.
