I have 3 bird of paradise plants in a 16" pot, and I am worried that they are getting too crowded. I water them 1-2 times per week and fertilize about every 3 months using 19-6-12 Osmocote smart-release plant food. I live in Seattle, WA, so they have been inside about October-April, and I just moved them outside.
I understand they like to be crowded, but I wonder if their current condition is too crowded. Should I divide them, or get a bigger pot? Or should I just leave them as is?
