Why these dates

Very hardy. Dies back entirely and reappears early in spring.

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. Lovage 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 Karaj.

Hardiness is not the obstacle here. Karaj is zone 6b, 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 2, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
