This is a logbook, not a field guide
Never eat any wild food unless you are certain of its identity by your own means. Some wild food
is deadly, and a few of the worst mistakes look ordinary. Nothing on this site identifies anything, says
anything about edibility or toxicity, or vouches for a single find — it records rain, frost, daylight and
the notes you write yourself.
Harvesting is yours to get right too. Permits, protected species, harvest limits and permission to be on
the land differ from one place to the next and change from year to year. Read and follow the rules for
your own jurisdiction and the landowner's wishes; this page holds none of them.
Flush window
A rain event here is any day in the forecast with 10 mm or more of
precipitation. The flush window is the stretch from 3 to 10 days after it. Rain on two days
close together makes one longer window, not two.
This is a rule of thumb, not a prediction — a guide to when a walk may be worth
the time, and not a forecast of what a walk turns up. Many fungi fruit some days after a good soaking; plenty do
not, and plenty fruit with no soaking at all. Ground temperature, what is under the leaves and the year
itself all matter, and none of them are in this number. When no day reaches 10 mm this page says so
rather than offering a smaller figure to fill the gap.
Frost
The figure is that day's lowest forecast temperature, which normally falls just before
dawn; every night in the window is in the forecast table below. Hard frost is −2 °C or below,
frost is 0 °C or below, and frost risk is 2 °C or below — on a clear, still night the ground
and the leaves on it radiate heat away and go several degrees colder than the air a forecast measures. This
is the same classification the Gardener's bed page uses, from the same code.
A hard frost changes what a patch is doing, and this is the forecast for the next
few nights — not a date, and not a statement about any particular thing that grows there. What your own
ground does after a frost is worth writing down in the template; it is not something this page can tell you.
Day length
Day length for the patch's coordinates, and whether it is
lengthening or shortening — the seasonal marker that does not care what the weather did this week.
Astronomy, so it works with or without the forecast.
