Unless you have a serious ground freeze, frost will only hurt the tops. The
most profitable strategy, then, is to time it so that the tops emerge just
after the last frosts. Even at that, potatoes can endure a very light frost.
It
has to be below 30 or sometimes below about 28 to do them any harm.

If frost does bite off the tops, the potatoes will still grow. They will be
later and you will get a very great number of little potatoes rather than a
few big ones, but the yield will be about the same. The potato only uses its
store of starch until the first leaves hit sunlight, then it stops completely
and depends on photosynthesis. With an average seed piece of one ounce, you
have the reserves for the tops to be burned three or four times before it
would
not have enough starch to recover.

The most profitable scheme is to plant them in threnches AND hills. Plant
them in shallow trenches 4" deep or so and cover them to ground level. As
they
grow, hill the dirt around them until the hill stands 10" high or bigger.
When the potato blooms, it's useless to hill it any farther. The potato will
not
set tubers deeper than you planted the seed piece and it will not set any new
stolons once it begins to bloom (or before that).

As far as planting dates, you can't go far wrong with Yukon Gold. They are
so extremely early that you can plant them in August and still get potatoes
(no, I'm not kidding). They don't store so very well and are subject to
'hollow
heart', but none the less are one of the best homestead potatoes there is.

No need to 'chit' certified seed potatoes. The potatoes know what they are
about. You need to sprout store bought eating potatoes to make sure you''ve
worn away the chemical sprouting inhibitor, but this is moot with
unadulterated
seed potatoes.

Plant plenty of potatoes! This is going to be a dicey year and no one is
going to starve with a bin of potatoes in the cellar.
