Frost
The blackened, limp tissues of frosted annual plants are a
common sight in fall and occasionally in spring. Such
injury on landscape plants may be less obvious and go
unnoticed until later. Spring frosts are more of a
problem than autumn frosts because landscape plants will
usually have developed some cold tolerance by early
autumn.
Frosted flowers and new growth will be limp and turn
brown. The browned and dead new growth of evergreens can
remain on the plant until well into the summer. When
noticed then, the frosted growth raises concerns about
diseases when, in fact, the injury occurred many weeks
before.
