Managing Through the Seasons

The growing season here arrives late and ends early relative to a lowland climate at the same latitude, bounded by frost risk rather than by the calendar or daylight hours the way a boreal climate's short summer is. The exact window varies enormously by specific altitude and location, so the pattern to plan around, rather than fixed months, is a compressed season that can close again with little warning at either end.

Even during the nominal growing season, daily freeze-thaw cycling remains the dominant day-to-day management task, exactly as covered in Chapter 11. That means "seasonal management" in this climate isn't really about warm-season tasks the way it is elsewhere; it's about deciding when to attempt to actively build and manage a heap at all, versus when conditions are too harsh even for the daily-protection techniques covered there to make real progress realistic.

Early and late in the short season, when overnight frost is more frequent and daytime warmth is weaker, it may genuinely be better to hold off starting a new heap and instead focus on protecting and slowly maintaining whatever is already underway, rather than fighting to establish something new against poor odds.

Outside the short growing window, a heap essentially goes fully dormant, similar in spirit to a boreal winter but covering a larger share of the year at real altitude. The worm bin covered in Chapter 10 should already be settled into its protected indoor setting well before this point, since worms don't have the option of simply going dormant the way a heap's microbial population effectively does.
