Against the frost risk in Cincinnati
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 Cincinnati.
The median frost-free season here is 195 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.
