the cops could do either, wait for you or rip them up. just dont tell any one that they are there. they are likely to survive if you dont water them but wont get the optimum size. make sure to water at first, when you plant them. when you go to your plants, take a slightly different path each time to avoid making a path. get some slow release fertilzer or plant spikes if you arent planning on visiting or taking care of them often.
