Thanks, Joe.
Having grown up in the Deep South, where I can't recall more than a couple
of snows deeper than 2" in my first 30 years down there (and none persisted
more than a couple of days), we didn't get much of that "Poor man's
fertilizer". Even up here in the frigid northland(southern west-central
KY! LOL) snows are not too frequent, heavy, or persistent.
The row-crop farmers have been planting corn, here, for better than a
month. I didn't notice how much, if any, damage the frosts/freezes of the
past two nights did to the corn I pass on the way to work - some of it's
close to a foot tall.
However, my hardy kiwis, raspberries, cucumbertree magnolias and newly
leafing oaks are all sporting wilted black foliage this morning.
