If Darius bleed can apply Conquerer why can’t Zyra plants?

Darius bleed doesn't apply stacks of conquerer, the auto he does or skill he does before does. Zyra's plants will proc conquere but each plant only accounts for 1 stack since they are classified as a dot. so if you have 3 plants up and they all auto one person you get 3 stacks. if she has conquerer proc'd the plants she spawns (or if she ultis since it "respawns" the plants) will start doing the truedamage.

Yeah, like Elewd mentioned, dots don't apply conquerors.
