As covered in 9.1 with nettle's winter stage, dormancy can look
like nothing is happening. In fact, root systems are very much
present and alive, simply waiting for the right conditions
to push new growth above ground again.

Emergence is usually triggered by some combination of soil
temperature rising, day length increasing, and accumulated
moisture from melting snow or spring rain. Different species
respond to slightly different combinations, which is part of
why some plants emerge weeks before others even in the same patch.

Experienced foragers often learn to read a patch of ground
before any green is visible at all — softening soil, melting
patterns, the particular smell of thawing earth. As covered
in section 1.1, your body is often sensing these shifts
before your eyes confirm them.

Fiddlehead fern shoots, as covered in section 5.1, seem to
appear almost overnight once conditions are right, with a
narrow window before they unfurl. Other plants, like ground
elder, tend to emerge more gradually over a longer stretch.
Knowing which pattern a given plant follows helps you time
your visits.

A warm spell can trigger early emergence, only for a late frost
to damage the tender new growth. This is a natural risk plants
take every year, and it's worth noticing if you're foraging
early-season shoots — frost-damaged growth often looks wilted
or blackened and is best left alone.
