I was looking at the long range weather forecast and, if they are any where near accurate the will no sub-zero weather in min-Minnesota (sixty miles North in Brainerd probably quite different) but there will also so no January thaw.
(never did like those) with no sudden drop in temps in Feb. or March. but a steady warm up each week or so.
IF, if that is any where close to accurate, may get the garden in in early May.
