I'm a fairly new resident of Arizona. Can someone recommend a good
fertilizer for palms? I have a Mediterranean Fan Palm that is beautiful
and has been growing quite quickly. However, this summer some of the
fronds are starting to yellow. I have been using a dry granular palm
food but I have been told that I should use liquid nitrogen. Does anyone
have any experience with this? What should I look for and where can I
purchase it?
