I would use a little of some regular Miracle Gro shake 'n feed, Osmocote or Peters and then use some of the indoor palm fertilizer. What kind of palms are you growing outside in the ground?

nashwinter, hey I'm in CT myself (Hartford) and I'm a serious palm nut. The Virginian gave you some good recommendations.

I just wanna put in my 2 cents also. You can also try Scotts Palm Container Food 12-4-12 with miconutrients. Also you can try Apex 13-4-12 Palm Special with micronutrients.

The Scotts stuff you can get through Griffin Nursery Supplies 203-699-0919. To get the Apex fertilizer you can try a west coast nursery supplier or a mail order company like Horizon online 800-782-8873.

Good luck
