We purchased a couple of Bee Balm plants about a week ago. I put them in a cedar planter, along with another Bee Balm plant that we've had for a while that was planted in the ground. The transplanted BB wasn't doing good in the ground. The leaves don't look healthy, they've got white spots all over them. I'm wondering if the unhealthy one is diseased and should be discarded so as not to infect the healthier plants. That same kind of spotty leaf is also on another plant, but it wasn't near it. Also, what is the difference between Bee Balm and Grand Mum Bee Balm? The Grand Mum is the one that's sickly looking. I've attached a comparison of the healthy and sickly looking leaves.
