How long for sheep to grow wool?

[Potjeh]

Breed sheep with higher wool quantity stat. Though I wouldn't really focus on that, you don't really need all that much wool and quality is more important anyway.

Okay, but is breeding a better sheep the only way?

Yes. Mind you, the quality of lambs is capped by the fodder your ewes are eating, so you do need to raise that as well.
