When is the last frost in Memphis?

The last frost in Memphis usually comes around 10 March: that is the median of 2016–2025, so in about half of those years the last night at or below 0 °C came later. Hardy crops start before it and frost-tender ones only after it: in the table below arugula can go into open ground from 17 February, while corn waits until 17 March. The first autumn frost follows around 23 November, about 258 days later: harvest or cover frost-tender crops before then.

Planting out: a week after the last frost once the soil is warm enough for the crop; frost-hardy crops three weeks before it; an unheated greenhouse three weeks earlier. Seedlings are sown so they are ready on that day. 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.

What planting zone is Memphis?

The official USDA map (2023, 1991–2020 data) puts the centre of Memphis (ZIP 38103) in zone 8a. Zone 8a stands for an average coldest night of 10 to 15 °F (-12.2 to -9.4 °C), so perennials hardy to zone 8a or a colder zone should come through a typical winter here.
