Where to buy tomato plants and seeds near Shostka

Buy plants ready to set out from 17 May to 30 June (from 26 April to 30 June for an unheated greenhouse); seed for raising your own is sown from 5 March to 9 May. 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.
