hey chronic, sometimes it does not rain for up to a month here in TN, so if their is no water near your plot(s) i would keep some water handy because i must water my plants 2-3 times a week in the heat of summer. i would think checking them at night would be more supicious than during the day. if you have a dog, or can borrow one, it will provide a good reason to be out in the woods. i usually check my plants1-4 times a week. also, i wouldn't put pots in the holes i would just plant straight in the soil, so the roots can get as big as they like.
hope this helps.
