Where to buy zucchini plants and seeds near Tver

Buy plants ready to set out from 16 June to 24 July (from 26 May to 24 July for an unheated greenhouse); seed for raising your own is sown from 5 May to 3 July. Within 15 km of Tver OpenStreetMap lists 9 garden centres, 2 farm-supply shops, 8 markets and 12 farm shops (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.
