I'm looking for the same on Bananas, but for Palms you can go to Home Depot.

In their fertilizer section, they sell little bags of Palm fertilizer ready made up and branded as such.

The bag's pretty small and contains pellets. Bag is about 3 lbs and seemed to last two feedings on everythign from queens to sagos. HD also has palm "stakes" from the same manufacturer....for larger palms, they look like railroad spikes and you essentially push these into the ground and they slowly break down over time.

Just buy 16-16-16, 0r 15-15-15 or what ever is balanced and cheap. Use lots of organic material (compost) with it and you will be fine. Supposedly 9-3-27 (a 3-1-9 ration_) is ideal, and I have mixed things to get that, but really can't tell any difference. Go cheap!!

Either a balanced fertilizer or one with a higher nitrogen number (first number) will be fine. I have done well with just plain old liquid MiracleGro. Results are even more dramatic if you spray on the foliage rather than just water it in.
