Potatoes planted in deep rows-covered in straw

I’m trying a lot of new varieties of vegetables this year besides the varieties I always plant. I’ve never planted potatoes before but thought I’d give them a try this year. I actually planted the potatoes on March 30 and am just now getting around writing about them. I just couldn’t wait any longer. I put them in my best bed that is 12 inches deep with very rich fluffy soil. I figure even if it snowed (which of course it did), the ground wouldn’t freeze up 3-4 inches below the soil where the potatoes are. Plus I got the drip in place (even though it isn’t turned on yet) on the potatoes and covered them with straw to protect them from the snow. I planted all fingerlings-French, Russian Banana and a purple variety. They are not up yet but can’t wait till they are. A brand new crop for me.
