Classic's De-eying Program
To de-eye, cut out the terminal/dominant buds or sprout(s) (eyes) using a small knife or tool pictured above. Staying within the diameter of the eye, remove the entire eye by cutting about 1/8” - 1/4” deep into the bulb. Remember, it is critical to stay within the diameter of the eye to eliminate damage to the small eyes (axillary or lateral buds) that surround the perimeter of the main eye. This is demonstrated first with a green bulb where the axillary buds are clearly visible.
Experiments using a nail to puncture and destroy
the terminal bud have shown good results. Remember in order to be
effective, the de-eyeing method must remove or destroy the terminal buds.
Please note however while proper de-eyeing increases the uniformity of
your crop, increasing the severity of the de-eyeing treatment, by
excessive removal of tuber tissue surrounding the terminal eyes, leads to
a less uniform crop.
