Perennial forages exhibit compensatory growth when small gaps or openings in the plant stands occur from physical (winterkill
) or mechanical (wheel traffic) damage.
An open area as small as a few percent of the overall water surface is typically sufficient to prevent a winterkill
. Keep in mind that the saturation level for oxygen in water is temperature dependent and that colder water holds more oxygen.
To winterize container-grown plants the grower must ensure that the root systems never experience temperature colder then -10C or winterkill
Rainfall was 312 mm between June 10 and October 9 Whereas winter wheat would winterkill
where residues are incorporated, growing winter wheat is possible where green manure crops are desiccated with their residues retained on the surface to provide cover and trap snow to control winter kill (Power 1990).
Effects of winterkill

When I remove the top growth from asparagus beds in late September, I plant a mix of winter peas and oats, which create a knee-high tangle of green by the time the ground freezes--and they winterkill
, leaving a thick, weed-suppressing mulch come spring.
Many factors have been blamed: Habitat encroachment, predation, disease, drought, winterkill
But the carrying capacity is quite low; even without winterkill
, population densities can't get too high.
Superintendent Bob Leblanc ranked the greens 8.5 on a scale of 10 after winterkill
dropped them to between 2.5 and 3 in each of the previous three years.
was not observed in any of the plantings.
Combine generally low harvest levels with a generally mild winter, which should reduce winterkill
, boost reproduction, and contribute to good antler growth, and the future looks bright, both short and long term.
And oats winterkill
better than the other grains, so I
