Evening Whistle

Sowing to Harvest

Start indoors four to six weeks before your last frost — Evening Whistle wants a long warm run and won't be rushed. Two seeds to a deep pot, on their edge, an inch down; thin to the stronger one. Set out only once the nights hold above 55°F, and give the vine a real trellis from day one: cattle panel, a stout fence, anything that will carry forty pounds of fruit without sagging. The neck cures straightest when the gourd hangs free, so train the vine up and let the fruit dangle.

Feed and water heavily through midsummer while the vine runs and sets. Then, once the shells reach full size and the rind dulls from glossy to matte — usually early September — stop watering entirely. The dry-down is what hardens the shell. Leave every gourd on the vine through the first light frosts; the stem will brown and shrivel on its own. Cut with a few inches of stem left on, never twist it off, and bring them in only when the vine finally dies back.

Curing the Shell

Hang each gourd by its neck in a dry, airy spot out of the rain — a covered porch is ideal — with space for air on all sides. It will mold on the surface as it cures; that's expected, not rot. Over three to six months the shell loses its weight and goes woody and light, and you'll hear the seeds rattle loose inside. When it's tan and hollow-sounding, wipe the bloom off with a damp cloth and let it dry a final week.

To open the voice, clear the stem-hole: pick the dried core out of the neck with a stiff wire until the channel runs clean down into the body. Don't widen it — the narrow opening is the whole instrument. Pour the seeds out, save your best for next year, and hang the shell back up by its neck where the wind can reach it.

Finding the Note

The note lives in the still hour just before an autumn wind picks up. Hang the gourd low and clear, neck down, somewhere a rising breeze will cross the open stem-hole straight on. When the air finds the hole it hums — one low, steady tone, lower than the size of the thing would suggest, the same way a bottle answers a breath across its mouth. A longer neck pitches it lower. Turn the gourd a quarter and you'll change how readily it catches; you're aiming the opening into the prevailing wind, not away from it. Once you've placed it well, it'll find its own note without you.
