If you have more time, you could add a visit to the Pykara waterfall, the Doddabetta Peak or go on a toy train ride from Ooty to Coonoor. If you have less time, you could skip Government Rose Garden to visit other attractions like the Mudumalai Wildlife Sanctuary or the St. Stephen's Church. Make sure to check opening hours, especially for Government Rose Garden, which is closed on Tuesdays.
