Care for lantana & zinnias?

I just planted these in my flower bed. Should I water them in the am first thing or in the evenings? I am a beginning gardner so all help is appreciated.
Care for lantana %26amp; zinnias?
I do nothing to my Lantana and it performs beautifully every year. A little water every now and again and your set. Same for Zinnia, however, they do like a bit more water when it's hot and it doesn't take much for them to thirst to death so just watch them for drooping.

Here is a good site on caring for zinnia:

Lantana can be very invasive. Mine produces small fertile berries, that make new plants where they drop. They'll then take over your garden.



Best is along a fence where you can control one side, and you don't care if new ones sprout underneath.



I know nothing about zinnias.
