SCAPE
BLASTING (or BLASTED SCAPE): |
The
sudden bursting, splitting or severing of a daylily scape in
the middle. Scape blasting is usually caused by heavy
rain following a period of drought causing a rapid
increase of internal pressures within the scape. Fertilization
just prior to or during a swift increase in soil moisture
may contribute to scape blasting. Sometimes the rupture
is complete, and all blooms are
lost. At other times the rupture is partial and the
daylily will continue to bloom. Should the scape not
separate completely, the break can be supported with
ice cream stick splints and duct tape. Scape blasting
has been attributed more often to tetraploids than diploids,
possibly because of their thicker, less flexible cell
structures. |

The
image above shows a blasted scape a few days
after the scape has burst. The buds continue
to be fed, but they are held on by only a small
section of the original scape.

This
image on the left shows a scape that has
blasted from top to bottom (or vice versa).
Most often a blasted scape resembles a spent
fire cracker, with sections of the scape
being blown out in a number of directions,
but internal pressure can also cause the
scapes to split vertically as shown.
