I set these pots out in Walkers yard early yesterday morning,7 yucca and 4 cactus,in an area that will not grow grass or weeds,And he left them alone, he wandered through and around them several times, going to set a few more out today and see what happens.If I could I would like to put them in the ground,(I'm tired of looking at dirt and maple tree roots).he's in the background grazing on weeds.
