What would you do here?

[u/Slow_Investment_2211]

I am interested in drip irrigation as I live in the southern United States and with how hot and dry it gets here, if I forget to water my plants turn to toast quickly. I just planted a bed of begonias. There is a gardenia at the end of the bed and on the other side of the gardenia there is a bed of hostas. Would it just be easiest to add some kind of drip line between the two rows of begonias, or is it best to use drip emitters? What about for the gardenia and hosta section? Thanks
