watering native plant schedules (new and established)?

I have my own māla, and I’m growing in ground native plants in Makakilo (dry hot low elevation), like ʻūlei, ʻaʻaliʻi, ʻilima, ʻākia, etc.

I’m trying to figure out a good basis schedule for watering?

I’ve heard every 4th day a week is good for thriving established plants, I water once a week for established plants after 2 weeks of every other day watering.

What’s your native māla watering schedule like?
