I'm in 4a so all of my growing is indoors as well. Mine do this and I really don't know why but it hasn't ever spread down the leaf so I just disregard it.

More or less weekly, I'd say. I try not to drown it, though.

I'm having problems with an indoor aloe, too. I'm in the same zone - how often do you water?

What's with the tips? I've read that I shouldn't water it too often, but it doesn't look too hot to my novice eyes. [photo](http://i.imgur.com/iXiR62V.jpg)

What am I doing wrong? I'm in zone 4b, if that's relevant, but I keep it inside.
