Wind shift and a drop in pressure — stake, tie in, and pick anything ripe before it arrives.
Writing your field guide — reading the forecast, the moon and the map…
Overhead · Minneapolis, Minnesota
The two clocks nothing on the ground can argue with: the length of the day, and the phase of the moon.
The sun
12h 33m of light

Sunset

A month from now the day will be 1h 33m shorter. Enough light for steady growth.
Right now · Minneapolis, Minnesota
Nothing here is a guess. Each of these is read from this week's forecast and this location's climate record, and each one is pushing the season one way or the other.
15.1 °C soil · 59.5 mm
Warm and damp: the fastest decay of the year. Compost cooks, leaf mould breaks down, worms work the surface — and mushrooms fruit two to seven days after a soaking rain.
Fungi and bacteria turning last season into next season's soil. The same warm, wet window that runs a compost heap also fruits the mushrooms.
59.5 mm / 7 days
59.5 mm across 4 days. About right; leave the hose coiled.
Sets the pace for everything: germination, fungal fruiting, slug nights, and how a river runs for the next three days.

The moon
Waxing Crescent
11% lit · waxing · day 3 of 29.5
Planting by the moon: New to first quarter: sow leafy crops and anything harvested for its leaves — lettuce, spinach, brassicas, herbs.
Fishing: good — feeding peaks in the days either side of new and full, and around moonrise and moonset.
Turn of the season
Fall equinox
Sep 22 · 7 days away
About 33 days to the average first frost (Oct 17).
Next moons
33 days
Average first fall frost is around Oct 17. Nothing you sow now will finish unless it beats that.
The hard edge of the growing season. Ice inside a leaf ruptures its cells — one night ends a tomato and sweetens a parsnip.
15.1 °C
Good for brassicas, beets, chard, carrots and potatoes. Wait on the heat crops.
Seeds read soil temperature, not the calendar. Six centimetres down is where the decision gets made.
12h 33m
Losing about 3 minutes of daylight a day.
The one thing weather can't change. Plants count photoperiod to decide when to bolt, bulb, flower and go dormant.
Waxing Crescent · 11%
Waxing, 3 days old. Full moon in 11 days. Fishing outlook: good.
It moves water — in the sea, in a lake's edge, and, by long tradition, in the sap of a plant. Fish feed hardest on the days around new and full.
