I noticed three pots with roots growing along the trunks. We've had lots of rain, and now no rain. I know the photo isnt very good. I took it with my phone, but the roots are visible, I think. Also, this is the first year I've had no blooms on any of the plumerias. I think all the rain and more tree shade has had some effect on them, but this is something new. And yes, I have fertilized them. Can anyone tell me what's up with them?
