Bent/"S"-shaped stalks are more common here in the fall than in the
spring, but don't always happen. The more erratic the temperature and
rainfall is, the more bent stalks.
Cultivars that are most prone to making bent stalks are just more
climate sensitive than those that can produce straight stalks under the
same growing conditions.
In the fall, those that manage to bloom here often have bent stalks, but
the later ones seem to be more prone to it than the early ones.
Especially those with rapid growth. Interaction of erratic moisture and
erratic temperature..??
forecast this AM was for scattered frost - following close on the heels
of record high temps. Talk about erratic!
Still no rain...
