Last time I played, I was able to manage my city garrison. However, garrison size is linked to food availability of a settlement. If you have zero food, I don't think you can store/manage a garrison. This could be the reason (?)

The above reply is right. In a city, the link to manage your garrison is under the "go to your keep" link, not in the main menu, like in a regular castle.
