Torts in the City

[Julia]

As I am preparing for the next tortoise season I wonder how many people keep their little treasures in the middle of cities, in city sized gardens, like me. I envy people who have lots of space and large meadows around, but I'm sure not everyone is so lucky.
For me the main problem is often where to get some fresh, clean weeds from, on a regular basis. What do other city owners do ? Do you give your pretty flowerbeds over to weed growing, or can you buy weeds somewhere?
I am also interested in garden designs that are suitable for tortoises, but also for their owners and families to use at the same time. I don't have the space for those special large square purpose built toroise enclosures. Any suggestions or a discussion would be welcome.
Thanks
Julia
