In Santa Paula, the garden wakes before the sun.
South-facing stone holds the day's heat into midnight. Sandstone warms faster than granite, releases slower. The frost retreats first from the red rocks.
Clay holds water tight—freezes late, thaws slow. Sand drains quick—freezes fast, thaws first. The Van Genuchten equation maps the boundary.
We do not fight the frost—we read it. Plant the peaches where the stone keeps warm. Leave the roses to the clay's slow thaw. This is the ledger that closes with warmth.
