Where to buy watermelon plants and seeds near Osh

Buy plants ready to set out from 6 May to 28 July (from 15 April to 28 July for an unheated greenhouse); seed for raising your own is sown from 18 March to 30 June. Within 15 km of Osh OpenStreetMap lists 6 markets and 1 farm shop (collected 27 October 2026).

Each window starts on the Greenly calendar date and ends on the last day that still leaves the crop’s days to harvest (from its card) before the average first autumn frost, plus six weeks of picking for crops harvested over weeks (tomatoes, peppers, aubergines, cucumbers, courgettes, pumpkins, watermelons, beans) — our rule; earlier in the window is safer.
