Coffea arabica 'Costa Rica 95'
1. Introduction & Taxonomy
Coffea arabica 'Costa Rica 95' is a high-yielding, disease-resistant cultivar developed by Costa Rica's coffee research institute (ICAFE) and released in 1995 after extensive selection and testing. This variety was specifically bred to combine resistance to coffee leaf rust with acceptable cup quality and high productivity, addressing the critical needs of Costa Rican coffee farmers. It represents Central America's efforts to develop regionally adapted, sustainable coffee varieties for modern challenges. Coffea arabica 'Costa Rica 95' is notable for reaching an impressive 8 m in height, its white flowers, its fragrant blooms.
The coffee shrub is originally native to the humid montane forests of Ethiopia and South Sudan between 1300 and 1900 m (4300 and 6200 ft) elevation, but today it is cultivated in many other parts of the world. In its wild state, it is a small tree, up to 8 m (26 ft) tall, but in cultivation it is usually pruned to a small shrub to facilitate the harvesting process. It has elliptical, shiny green leaves and fragrant, white flowers followed by yellow to purple fruits. Coffea arabica is the main source of our ubiquitous coffee, and it is also used in liqueurs, as a flavoring, as a source for caffeine, etc. It adapts well in humid tropical and warm-temperate climates. Costa Rica 95 is a compact variety adapted to hot, tropical climates and acidic soils. It produces a very high yield and decent quality coffee bean.

Seasonal Care Calendar
Follow this season-by-season guide for optimal care timing throughout the year.
🌱 Spring (March–May)
Main flowering season. Apply balanced fertilizer emphasizing potassium to support bloom and fruit development. Increase irrigation as temperatures rise and evaporation increases. Despite rust resistance, monitor for other disease issues. Prune if needed before flowering flush.
☀️ Summer (June–August)
Berry development and maturation period with high nutritional demands. Maintain consistent fertilization and watering schedules to support the variety's high productivity. Monitor for coffee berry borer activity and implement trapping programs. Shade management important for berry quality.
🍂 Fall (September–November)
Primary harvest season as berries ripen to bright red. The variety's large berries and good productivity reward careful selective harvesting. Implement thorough sanitation, removing all berries including over-ripe ones to control berry borer populations. Begin reducing fertilizer applications.
❄️ Winter (December–February)
Post-harvest recovery period. Reduce fertilization to minimal levels. Decrease irrigation while maintaining soil moisture. Optimal time for renovation pruning to maintain productive structure and manageable height. Assess plant health and plan next season's management based on previous year's performance.
5. Diseases & Pests
Coffea arabica 'Costa Rica 95' 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

Frequently Asked Questions
How does CR-95 compare to other rust-resistant varieties?
CR-95 has good rust resistance, though perhaps not quite as robust as some newer varieties like Castillo. Cup quality is generally considered superior to early-generation Catimor types but may not match heritage Bourbon or Caturra at their best. The variety represents a good middle ground between disease resistance, productivity, and quality, making it economically viable for Costa Rican producers who can achieve specialty coffee prices.
Why isn't CR-95 more widely planted outside Costa Rica?
CR-95 was specifically bred for Costa Rican conditions, particularly the altitude range (1200-1700m) and climate patterns of that country. While it performs in similar Central American environments, it hasn't been as extensively tested elsewhere. Additionally, other countries developed their own adapted varieties (like Colombia's Castillo series). The variety is available primarily through Costa Rican sources, limiting international spread.
Can CR-95 be grown organically?
Yes, the rust resistance makes organic CR-95 cultivation significantly more feasible than susceptible varieties. However, even resistant varieties benefit from preventive organic fungicides (copper-based) in high-disease-pressure conditions. Organic production still requires careful management of berry borer and soil health, but the reduced need for synthetic fungicides makes organic certification much more achievable than with Caturra or Bourbon.
Is CR-95 available for home growers?
CR-95 seeds or plants are occasionally available through specialized coffee plant nurseries, particularly those connected to Latin American sources. However, it's less common in the hobby trade than varieties like Caturra or standard Arabica. For home growers, the rust resistance is a nice feature but less critical than for commercial production. The variety's moderate size works well for container growing.
