I just got a rude awakening when I was watering H. Choo Choo Train. I thought the stems were laying down because it needed water. WRONG!!! ALL the roots are gone and you can see where the crown has been chewed on. This is/was in a maybe 25 gal pot, sitting on bricks off the ground.
I had found H. Brother Stefan like this in August and thought because of all the spring/summer rain we had, it had rotted!!!!
So far the count is four down and the pots are all in the same area.
For us 'pot' people, make sure your pot is not too close to the ground!!! What a bummer.
