It sounds like a real nice garden you are planning, and hehe I am sure it wont be as pleasant when the bill comes. I have to tell you a little story about planting that did not work out as well as we expected. Many years ago, we bought a house and did major landscaping changes there, my cousin who is a landscaping designer, helpt us and did a wonderful job. Only one slight problem, as a border of a very long curved bed alongside the driveway, he planted catnip!!!!!!!! I was not very familiar with plants back then (not a great gardener now either lol..) so I had no idea it was catnip, until a fewweeks later when it got warm and nice and they really started to grow, then we had the entire cities cats laying on, in and around our flowerbed, not only did they sit and lay on it, they ate it, rubbed themselves on it and were about to give our dogs a heart attack, they liked our cats, but this was little too many of the feline kind for their taste lol....
Now, we have dogs that, knock on wood, are pretty good with our gardens. But we have concentrated our plantings to the frontyard, we really dont spend much time there, it is mostly a "look good spot". We and the dogs spend most time in the backyard, have about an acre fenced in with privacy fence, so they can run around and have a good time, and the kids can be there with them and play. The only place they are not allowed is the area around the pool. Mainly because it is fenced in and since they are outside on their own too , I would be worried they'd fall in and drown.
Good Luck to you and hopefully you wont faint when the bill hits you.
