Yes!, to both! :-D

However, there is nothing stopping you from watering at any time of day,
so long as the water doesn't sit on the foliage and flowers in very very
hot sun.
This is where scorch problems can start.





What causes the scorch? Is it the water droplets acting as miniature
lenses focussing the sunlight onto the leaves burning / overheating them
or is it related to the water evaporating in the hot sun?


That is the folklore answer, but it doesn't seem to hold water, if you'll
pardon the pun. AIUI a drop of water on a leaf is not sufficiently spherical
to have the optical quality necessary to cause scorching. If it did, somone
would be able to post pics of the scorching.
