  1. Between noon and 4 p.m.
  2. Between 6 p.m. and 10 p.m.
  3. Between 3 a.m. and 10 a.m. ✔

Why: Pasture sugars are lower in the early morning hours. UMN Extension suggests susceptible horses graze between 3 a.m. and 10 a.m.

Huh, didn't know that: UMN says most forage plants store sugar in the bottom 3 to 4 inches, so avoid overgrazing.
