Where to buy watermelon plants and seeds near Shostka

Buy plants ready to set out from 30 May to 11 July (from 9 May to 11 July for an unheated greenhouse); seed for raising your own is sown from 11 April to 13 June. Within 15 km of Shostka OpenStreetMap lists 3 markets (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.
