Aubergines through the year
Against the frost risk in Yaroslavl
Why these dates
Aubergine roots resent disturbance and cold. Waiting an extra week for warm soil consistently outperforms planting early and hoping.
Killed at 0C and set back badly by anything under 10C. In cool-summer climates this crop belongs in a greenhouse or polytunnel.
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. Aubergines are timed from 8 weeks before that frost for an indoor start, with planting out 3 weeks after it, and this page simply resolves those offsets against the frost date computed for Yaroslavl.
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 151 days, against 65 to 80 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.

Can I plant aubergines earlier in Yaroslavl?
Frost is finished by about 29 May, but the soil is still too cold. Aubergines will not start until it reaches 18°C (64.4°F), and here that is around 1 Jul. Going in earlier usually means seed that rots or transplants that sit and sulk, and a later sowing catches them up.
