Feeding Tort's Turtles?

[Dani33]

At what time of the day do you feed your turtles/torts thier veggies/greens/fruits? Also, how long do you leave it in thier enclosure?

My little CA wood seems to like taking a nibble every now and than. So, I've been leaving her a salad to nibble from all the time. I was also setting it out in the morning. She also appears to be active/inactive at different parts of the day/night. I forget the word(not nocturnal or diurnal). So, I'm not sure as to when to set the food out. If I do in the morning, the food obviously isn't fresh the next morning (not rotten by any means). Should I try and force her to just eat for a certain amount off time - say the morning for 20 min? Or does it depend on the individual. What do you think?

Thanks in advance.
