That is normal leaf scenesce. Notice that the most dry and shriveled leaves are the oldest and lowest. You may be underwatering a little, causing the plant to resorb and recycle the leaves water and nutrients. They look fine to me. No worries. You can remove the lowest leaves when completely dry.

Red Pony,

In the spring, I'd think the plant would benefit from a repot in fresh, more porous soil. Cut the soil you're using with perlite at a 50/50 ratio.

Brad,

I was thinking that myself, but have too few large agaves to have been sure.

I've been having the same problem with mine this year, which stinks, because they are from a much larger plant that actually grew in my yard in SC. Here in Buffalo, lol another story... I am due to re-pot mine, so, I'll check things out then...Thanks everyone !

I have three large blue agave that I have had for 5 years. This year when I brought them outside in western New York the stems started to look like the clorafill it going out of the stem and they are drooping down half way down the stems. Any ideas

That looks like A. americana, an enormous plant. Sooner or later, large Agaves tend toward general malaise when maintained in small containers. There are plenty of small Agave species far more suited for container culture.

KSE Interior Design, I'd suggest you start a new thread and post a photo or two as well.
