the weather here in the Phoenix area is wonderful for tropical plants it never snows here and even the worst Frost's aren't really all that bad there's a lot of sunshine and warmth and well just about everything except the soil is just awful that'll get me wrong the soil is fine for cactuses agaves and other desert adapted plants but it's much too alkaline for palm trees and cycads and that's why I say that my plants aren't really planted in Arizona they're planted in holes in Arizona filled with potting soil and coffee grounds yes coffee grounds I've been adding in coffee grounds here for years and years you can get it for free at coffee shops especially the ones that charge way too much for a cup of coffee and you can get it from whenever you make coffee keep a plastic container next to my coffee maker and I dumped the grounds they're not in the garbage first I just sprinkled the coffee grounds on top of the soil it looked nice for a while made my garden smell like fresh brewed coffee but once the coffee grounds dry up they look kind of rough on top of the soil and besides that's not what they're for there to mix in with the soil coffee grounds are acidic now don't panic I don't mean that you're adding a bunch of acid to your garden I just mean you're lowering the alkalinity and coffee grounds are organic which means they break down the soil and plants consume them so get some coffee grounds and mix it together with the soil the next time you plant something dig a big hole and mix it up with the native soil the potting soil and the coffee grounds tropical plants love it
