Sudden cold snaps and late freezes
On average, the first hard freeze of autumn arrives in mid-October,
but it can come a month earlier or later. An early hard freeze, with
temperatures at 27 degree F (-3 degree C), will burn the still-green
leaves of woody and herbaceous perennials, and even damage the twigs of
shrubs and trees that have not yet begun hardening. The last hard freeze
of winter falls in mid-May, but some years it arrives as early as March
and other years as late as June. Furthermore, false springs and tardy
winters bracket the growing season. Surges of southern air can arrive
anytime from mid-winter to spring, lulling shrubs, trees, and herbaceous
perennials partially out of dormancy. Once started, they lose hardiness.
When a new wave of cold arrives, as it usually dose, it can kill plants
outright. Even temperatures considerably warmer than the average low for
the zone can cause damage. In areas where snow is heave, herbaceous
perennials are usually spread from premature awakenings. Where snow is
sparse, as it often is on the plains, exotic species such as daffodils
that are not adapted to false springs often emerge too soon and are
burned by the return of deep cold.
In the areas of Zone 5 with adequate rainfall, the main crops are soybeans, corn, wheat, and oil seeds such as sunflowers. The hardier tree fruits such as apples and pears are grown, but require frequent spraying for the insects and disease that can thrive.
