Worth recalling that when Saint Patrick returned to Eire so he might preach the word there were no Potatoes in Europe. And too there were probably no Potatoes in this part of Kentucky so quite why a gardener should plant his Potato on Saint Patrick's day, I've got no clue.
The problem, as I see it, flows from Potato growing season here where I live.
They don't like it too hot, and heat comes here quickly which means that a
Potato planted in the middle of April does struggle by middle of June. So it's
all down to what kind of Spring a gardener thinks might be possible. Let's hope
for long days and cold rains through the end of March well into April and if
there is to be frost let's hope it's gentle.
