Asparagus gouge
White asparagus can be harvested with an asparagus cutter or an asparagus
gouge. The latter has a gouge-shaped (approx. 3 cm wide; approx. 10-15 cm
long) blade that is attached to a wooden handle with a long (approx. 20 cm)
tang. White asparagus is grown on high beds and harvested just before the
foliage comes to the surface, because when the head is exposed to light, it
quickly turns blue or green. With an asparagus gouge or knife it is
possible to cut the stem as close to the rhizome as possible, without
damaging these or not yet fully grown, neighboring stems. [MOT]
