First Time grow in az

Hello , so i have this plant growin in the backyard, and its only source of anything is the sun since i dont give my plant anynutrients , but since az sun is more intense i was wondering how to care for it ?? as in how i should water it , i figure since its hotter i have to water more than usual? any help would be greatly appreciated

Im still really new at all of this still but i can tell you that you should water it when the sun it at its peck i heard it will burn the roots up well cook em. give around hour before dark or before light. that what i would do. like i said im a newbi.
i like your location for the plant by the way.
