Zinnias through the year
Against the frost risk in Sohag
Why these dates
Direct sowing after last frost usually beats transplanting - zinnias dislike root disturbance and catch up quickly.
Killed by the first frost at either end of the season. Strictly a warm-season flower.
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. Zinnias are timed from 4 weeks before that frost for an indoor start, with planting out 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Sohag.
