Where to buy watermelon plants and seeds near Kremenchuk

Buy plants ready to set out from 28 May to 29 July (from 7 May to 29 July for an unheated greenhouse); seed for raising your own is sown from 9 April to 1 July. Within 15 km of Kremenchuk OpenStreetMap lists 12 markets and 4 farm shops (collected 28 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.
