Simon is spot on - I have covered with shade cloth maybe parts of 7-8 trees as a precaution
I've got some mangoes next to walls or exposed in some other ways which can be
quite debilitating at these temps, but no, in general, a few days of 115 - 120 probably wouldn't kill
a tree that's at least say 3 years old....a branch possibly but only those fully exposed to the sun.I have a bunch of new
growth that I want to try and save on some trees so I took the effort to cover them. It is getting
difficult as they get taller so those bigger trees are on their own and actually seem to be get through it fine.
The biggest problem I have (and I wonder if Debra Wong with her mango trees down in the East Valley has them)
is fruit scald/burn from sun-exposed fruit. I can't imagine she doesn't bag them or something so they are
protected because she def. couldn't sell them at any farmer's market. It usually causes early fruit drop
that what would otherwise be a promisingly great mango down the road, but even if it makes it to full ripeness
it carries a very damaged top usually around the stem. I should email and ask her.....
And I will confess, I do baby my trees (children) perhaps more than most growers
