Well, it's official. They do well up to 108 and full sun but beyond that
they bake to a crisp. We hit that temperature last week and the next day
they were turning brown and becoming brittle. If like last year they'll
all die off in a couple of weeks.

Water lettuce seems to love the heat though. Normally I'm throwing them
in the mulch bin but this year the fish are going to need them for shade.

I've been hearing that many ponders are putting up shade when they've never
had to before. Any chance you could do that? ~ jan

I've thought about putting up a tarp over the pond but never got around
to it. My wife bought me some water lettuce at the start of the season
and it loves the heat. I'd say that I have 80%+ surface coverage of
water lettuce. In fact, they're growing so quickly that I started
tossing some in the mulch pile recently. I thought I'd leave it until
the heat breaks.
