Bolting in cole crops
Bolting occurs when flowers develop too quickly. For seeds planted in the spring, flower stalk initiation
in cabbage is stimulated by prolonged cold temperatures below 50° F. For fall-planted seeds, plants may
bolt if they start to grow quickly and are then forced to slow down by cold temperatures. Bolting cannot
occur until plants have received the cold chilling in the winter.
Plan to plant when environmental conditions during development will not stimulate bolting or the growth
of flower stalks.
