Post Droopy agave leaves
We've recently noticed one or two of our medium sized americana leaves
starting to droop.Is this down to heat stress?The garden is south facing and
with the recent weather can get very hot.In the Agave book by the Irishes'
they say that this can be quite a bad problem.I know what you're thinking
Paul,get a decent agave in there instead!The plant has been in the ground for
about four years and is approx. three foot tall.

It is just a temporary thing to do with the heat plus being dry. My americana do it all the time, but it is nothing to worry about as far as I can see. If you think about it, Agave americana grows throughout the Mediterranean countries - even in places like Sicily and Greece where day time temps can reach the upper 40s - so the small amount of heat that we can generate in this country isn't really going to trouble it.

Mmmmm...don't know I'd agree with you there Paul. My giant specimen used to have rigid leaves when it was stuck in a pot and semi-starved for years, but when I unleashed the roots it started to grow very vigorously and became floppy leaved. I associate floppy leaves with vigorous, soft growth in an easy climate like ours. For example, most of last years growth was floppy, right through the wet, cool summer.

Post drooping is normal
Here in California it's very common to see large agaves w/some drooping leaves. Here's a smallish agave Americana growing in my front yard that shows some flopping of the leaves. But really it's fairly common, from my nonscientific observations of Calif. Image

So there you have the definitive answer, Mike - it droops because it is either a/ too dry and hot or b/ too wet and cool. :)

Nick - mine behave very differently from yours, I guess, as I never get vigorous soft growth here!

The leaves on my quite large potted A. americana are rigid when young and progressively recurve as they age, such that
they eventually look like the ones in Matt's picture from Eureka. So it doesn't seem to be related to the growing conditions
when they emerge - they stay rigid for a year or more. Before they die off, they are so recurved that they hang down
below the level of the table that the pot is on.

There are three smaller offsets from this plant on the roof - utterly different growing conditions, except that they're all kept
quite dry in Summer - and, in their miniature way, they are doing a similar thing.

I think it's likely that genetic variation plays a part in this. A. americana is not a species that lends itself to generalisations.

Thanks for the responses,it's just confusing as a lot of the lower leaves are
still very rigid,it's just couple of the more recent ones that have drooped.
Also like I said, the plant has been in the ground for a few yeas now, so
it's not as if it has just come out of a pot.
Could it be the fact that we regularly cut off the base leaves when they
encroach onto other plants/agaves, which could be stressing the plant?
