I'm a relatively new gardener, planning a landscape with only drought tolerant plants. I keep reading about watering plants a certain amount of time until they are established. How do I know when this is? I read online somewhere that it takes a year of biweekly watering for flowers, small plants. This seems like forever to me and I'm wondering what your opinion is. Is there a way to tell?

Also, would you recommend planting in fall rather than in the next few weeks? I know summer is hard on plants, however I'm dying to get started.
