Against the frost risk in Sterlitamak
Why these dates
Very hardy, to about -25C.
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. Hyssop are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Sterlitamak.
Hardiness is not the obstacle here. Sterlitamak is zone 4a, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 1, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
