Coffea arabica 'Obatã' is a premium arabica coffee cultivar known for quality bean production. Seeds require extended germination periods of 30-70 days and demand consistent moisture, warm temperatures (20-25°C), and high humidity to successfully develop. This variety exhibits moderate germination difficulty due to the slow, lengthy germination process characteristic of coffee seeds.
Before sowing
Use fresh seeds; viability drops significantly after 3 months unless stored at low temperature and high humidity. Seeds must maintain moisture content above 15% to remain viable.
Sowing
What to expect
Tips
Soak seeds for 48 hours before sowing to accelerate germination. Keep substrate consistently moist but never waterlogged to prevent damping-off disease. Maintain humidity with a dome or plastic cover; remove it gradually after sprouting. Germinate seeds in darkness or under filtered light, maintaining temperature between 20-25°C. Use fresh seeds harvested within 3 months for best results. Place seeds flat-side down in substrate, lightly covered. Do not let soil dry out during germination phase. Radicle emergence begins around 3-4 weeks; cotyledon leaves appear at 4-6 weeks. Once seedlings emerge, gradually transition to bright indirect light.
