Water requirements for young plumeria using drip in heavy clay soil

Hi all, I recently planted a young plumeria (5 gal pot) into the ground. In my area, I have heavy adobe clay, with only a centimeter of decent top soil since I started mulching. The drainage is far from ideal, but I've lightly amended the surrounding soil five times the size of the pot in both width and depth. I amended lightly because I didn't want to create a bathtub effect (I mixed 4 parts native soil with 2 parts 'amendment' product which consists of nearly composted 'forest products/wood chips' and gypsum).

I irrigate my landscape using drip irrigation and wanted some advice on water requirements, especially from others with a climate and soil type similar to mine. Approximately how many gallons per week is necessary for a young tree like mine?

Do plumerias prefer a consistently moist soil or do they prefer to be watered deeply but infrequently and dry out between waterings?

Thanks, any advice would be greatly appreciated
