Hi Jim!  I planted a Carrotwood tree about a year ago. It seemed to have been doing ok in the full sun with regular water until a few months ago when the leaves started to get some yellow spots on them. I've planted other Carrotwoods many times before, but this one just doesn't look healthy. Is this due to over or underwatering, or something else entirely?  Help!
Thanks, Stan
Answer -
I would not recommend planting Carrotwood it has been classified as an invasive plant and banned in several states as well as by the US Government. Here is a web site for Florida:  http://aquat1.ifas.ufl.edu/cupana.html
Invasive alien plants typically exhibit the following characteristics:

1. Rapid growth and maturity
2. Prolific seed production
3. Highly successful seed dispersal, germination, and     colonization
4. Rampant vegatative spread
5. Ability to outcompete native species
6. High cost of removal and control
Invasive alien plants thrive in disturbed sites. Native plant communities fragmented by human disturbance are most vulnerable to invasion, but the most invasive species can infest even intact ecosystems. Invasive alien plants are free of natural controls such as insects and diseases that keep them in balance in their native habitats.


Thanks for your reply Jim, but are we talking about the same carrotwood tree?  I've planted tons of them, and there are MILLIONS of them in L.A. and none of them display any of the characteristics that you described above.  I also doubt that all the nurseries in L.A. would sell them if they were banned.  All of the landscapers that I've worked with have highly recommended them due to their low maintenance, medium growth and non-invasive root systems.  Could you check to see if we're about the same thing (long medium narrow crinkly leaf, 3 to 4 inches long, evergreen) Still wondering about the yellowing leaves.  
Thanks, Stan.


Answer
Check the pictures on the web site I sent and see if it is the same tree. http://aquat1.ifas.ufl.edu/cupana.html Sometimes different trees have the same common name. As far as the yellowing leaves I would suggest checking with a nursery that sell this tree for advice OR call the Calif. Department of Forestry, (State agency) they should be able to help.
