I would allow picking of seasonal veggies from the garden.  

So I stop by and drop veggies from the garden.

I also want to thank you as I found a vegetarian/vegan place (La Vida Veggie) right next door that I'm definitely going to have to try. :-)

Did I spell the veggie right?

Eggs, Milk, Bologna, Bread, Veggies, butter..

i would let them have one,, your tennant will think you are a real jerk if you say she cannot grow some veggies !

Does having an organized garden that produces fruits and veggies raise value of a house?

Then turn the lots into community gardens were the neighbors could grow veggies and fruits and do it all on the honor system..We see that here in Oregon there will be a little stand in front with freshly harvested fruits or veggies with a donation can ( Coffee can) and you just pull over and grab some tomato's or such and then leave your money in the donation can.. and every few days the volunteers that are tending the garden come by and empty the can.. and use that to buy things to better the garden...

It's a nice house with a big backyard that is mostly covered by my veggie garden.

Knowing the tenants, they really just buy fresh food  veggies and fruit and not much they can pop in front of vents.
