Coffee flowers form when the plant’s C/N ratio (carbohydrates to total nitrogen) is high.
To achieve this, apply the following measures:
-
Increase carbohydrate reserves by creating conditions for strong photosynthesis so the plant accumulates more sugars and starch.
-
Reduce nitrogen levels by stopping nitrogen fertilization or reducing nutrient uptake—for example, by withholding irrigation.
After the flower buds have differentiated during the dry season, they develop into dormant buds that wait for suitable humidity to bloom.
Practical steps for synchronized flowering:
-
Stop irrigation for 45–60 days to allow flower buds to form.
-
When buds reach the mature “split-beak” stage, irrigate thoroughly to trigger bloom. About seven days after watering, the flowers will open simultaneously.
