age, they'll already
be sprouting. Sprouting in October is acceptable for the remainders
of my St. Pat's Day sowing that I am keeping over for seed next
spring. It is not ok for my main winter storage crop. Our climate
requires very late, slow-maturing varieties that can be sown early
but that don't brown off until September. Late types usually yield
more, too.

Most of the seed potato varieties found in garden centers are early
or midseason types chosen by farmers for yield without regard to
flavor or nutrition. One, Nooksack Cascadian, is a very late variety
grown commercially around Bellingham, Washington. Nooksack is pretty
good if you like white, all-purpose potatoes.

There are much better homegarden varieties available in Ronniger's
catalog, all arranged according to maturity. For the ultimate in
earlies I suggest Red Gold. For main harvests I'd try Indian Pit,
Carole, German Butterball, Siberian, or a few experimental row-feet
of any other late variety taking your fancy.

Rutabagas

Rutabagas have wonderfully aggressive root systems and are capable
of growing continuously through long, severe drought. But where I
live, the results aren't satisfactory. Here's what happens. If I
start rutabagas in early April and space them about 2 to 3 feet
apart in rows 4 feet apart, by October they're the size of
basketballs and look pretty good; unfortunately, I harvest a hollow
shell full of cabbage root maggots. Root maggots are at their peak
in early June. That's why I got interested in dry-gardening giant
kohlrabi.

In 1991 we had about 2 surprising inches of rain late in June, so as
a test I sowed rutabagas on July 1. They germinated without more
irrigation, but going into the hot summer as small plants with
limited root systems and no irrigation at all they became somewhat
stunted. By October 1 the tops were still small and a little gnarly;
big roots had not yet formed. Then the rains came and the rutabagas
began growing rapidly. By November there was a pretty nice crop of
medium-size good-eating roots.

I suspect that farther north, where evaporation is not so severe and
midsummer rains are slightly more common, if a little irrigation
were used to start rutabagas about July 1, a decent unwatered crop
might be had most years. And I am certain that if sown at the normal
time (July 15) and grown with minimal irrigation but well spaced
out, they'll produce acceptably.
