Before the statisticians take me to task, these were relatively small
samples; typically 5-20 cells, 3 seeds to a cell, seedlings counted before
thinning.

Looks right to me; plenty of seeds for statistical accuracy. Most
published refs give around 4 years for tomato seed viability, with some
stating up to 10.

It's a dismal day on the (New) York colonies; barely above freezing with
just enough coating of snow/sleet/slush to make staying indoors reading
garden catalogs a Really good Idea.

It's a very pleasant early spring day here. Yesterday was the warmest of
the year so far at 18 or 19C; not quite as warm today - around 15 or so.
A good day to start removing winter protection; we will probably get a
frost or two, but nothing penetrating. We could do with some rain,
though (apologies to David in Wales! It's been chucking it down there, I
am informed), as there has been only 10 mm rain in the last 20 days. Add
to that incessant winds, and any unprotected soil has dried out.
Fortunately, I put down 50+mm of woodchip mulch on the beds late last
autumn, and they are nice and damp underneath it.
