Slugs work all day, not just at night, and blight moves in wet warm air.
- Ground beetlebest now — Running the soil surface after dark, taking slugs, cutworms and larvae. One of the best predators a garden has.
- Earthwormbest now — At the surface after dark and in wet weather, pulling leaves down into the burrow.

Planting by the moon: Last quarter to new: a resting phase — weed, prune, harvest, turn compost and prepare beds.
Anglers' solunar rating: good — the tradition says fish feed hardest in the days either side of new and full, and around moonrise and moonset. The evidence is mixed; light and weather matter more.

Forces at work right now
Frost, soil warmth, light, rain and the moon set the pace for the garden, the water and the woods alike. Every reading below comes from this location's own forecast and climate record.
- Worth watching
Frost
42 days
Average first fall frost is around Nov 18. 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.
- Working for you
Soil warmth
18.2 °C
Warm enough for beans, corn, squash, cucumber and transplanted tomato and pepper. Roots run hard at this temperature.
Seeds read soil temperature, not the calendar. Six centimetres down is where the decision gets made.
- Quiet right now
Day length
11h 26m
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.
- Worth watching
Heat units
27 GDD / 7 days
Slow accumulation — cool-season crops are happy, corn and melons are waiting.
Growing degree days: the running total of warmth above 10 °C. Crops and insects both run on this clock rather than on dates.
- Worth watching
Rain
18.3 mm / 7 days
18.3 mm across 2 days — short of the ~25 mm a week most beds want. Top up the thirstiest rows.
Sets the pace for everything: germination, fungal fruiting, slug nights, and how a river runs for the next three days.
- Working for you
Pollination
6 of 7 flying days
6 good flying days ahead. Open flowers will get worked — leave a shallow water dish out and hold off on any spray until dusk.
A third of what you eat needs an insect to have visited first. Bees fly on temperature and wind, not on your schedule.

Castanea sativa
A big tree with long, glossy leaves edged with sharp, regular teeth, and bark that twists in spiralling ridges on old trunks. The nuts come in twos and threes inside a husk covered in dense, needle-sharp spines; each is glossy brown, flat on one side, with a pointed tuft at the tip.

Has a dangerous look-alikeTreeSeptember – NovemberJuniper berries
Juniperus communis
Low spiky evergreen with needles in whorls of three, each with a white stripe on top; the 'berries' are fleshy blue cones that take two, sometimes three, years to ripen — so green and blue ones hang together.
