Luckily, we always get a lot of murky weather comes spring. Certain plants seem to have no problems whatsoever with the sun or water. Like my guava, loquat, wampee, white sapote, jabos, yangmei.... I also notice all of my garcinias have either died or completely defoliated under my greenhouse conditions except for my dulcis (mundu) - these guys can take some abuse.
Yes Make sure to keep them in shade.
I will sometimes place them in the woods for a bit to recover.
Or try to time it when its rainy/gray outside.
Sometimes they do get burnt a bit but then will grow out of it. Not the best practice
