Nope. They’d have a food allowance (as was mentioned). The garden would be part of a work program. Having a neat and productive garden would be one requirement for being released.
Not exactly breakin’ rocks in the hot sun...but something to keep them busy, and focused.
I read the food allowance. It would be wasted and they would likely starve if left on their own.
