I know Cedar wont do the best in zone 9 but almost every source Ive seen says they are hardy here and I have seen cedar of Lebanon growing in similar conditions to West Central Florida. My maybe 2 years cedar tree has had many new shoots (including the top apparently) just abort and I am confused as to why. I am worried it may be the intense heat we got the past week, and it currently lives in a pot in the shade to keep out the heat. I give it ice instead of water in the winter to at least give it some cold. I also had something similar to my Italian stone pine happen and the top died again, but it's doing much better. I don't know if it's disease, the roots seem intact and the pot is relatively moist but not very. Thanks for any help, I couldn't find anything on the internet.
