Step by step in Voronezh
Each window is a range, not a single day. Earlier in the range buys you a longer season; later in it buys you a safer one.
Sow direct
16-30 May
Held back until the soil is warm enough for this crop. The frost date on its own would say 4 May, which is too cold for it to start.
Harvest
5-15 Jul
Green beans through the year
Against the frost risk in Voronezh
Why these dates
Sow a short row every two weeks from one week after last frost until ten weeks before first frost. Beans crop heavily for a fortnight then decline, so succession matters more than quantity.
Beans are killed by the lightest frost at any stage. They also germinate poorly below 15C, so patience in spring pays.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Green beans are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Voronezh.
With one correction, which is the note at the top of the page: the offset alone would put this crop in soil that is still too cold for it. Where the frost date and the soil temperature disagree, the dates here follow the soil, because a seed in cold ground either rots or waits, and a sowing made a fortnight later usually overtakes it.
The median frost-free season here is 164 days, against 50 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing green beans in Voronezh
When should I plant green beans in Voronezh?
Aim for 16-30 May in an average year. If you would rather not gamble on the weather, wait until 18 May - 1 Jun - by then frost has finished in nine years out of ten.
Can I plant green beans earlier in Voronezh?
Frost is finished by about 4 May, but the soil is still too cold. Green beans will not start until it reaches 15°C (59°F), and here that is around 16 May. Going in earlier usually means seed that rots or transplants that sit and sulk, and a later sowing catches them up.
When will green beans be ready to harvest in Voronezh?
Expect to start picking around 5-15 Jul, based on 50 to 60 days to maturity from the planting date calculated for this location.
How much frost will green beans tolerate?
Beans are killed by the lightest frost at any stage. They also germinate poorly below 15C, so patience in spring pays.
