live in Austin TX which is a zone 8-9 climate. I enjoy the following trees, shrubs and plants in my countryside.

Cherry Laurels, Magnolia, Leland Cyprus, Sego Palms, Crotons, Crepe Myrtles, Italian Cyprus, Fountain Grass, Box woods, loriapi, jasmine, Oak Trees, and a bunch of other shrubs.

How often should and how long should I be running my automatic sprinklers?

Answers:    It is best to river once a week and make sure your plants/trees get hold of an inch of water. Watering 6 or 7 minutes a daylight wastes hose down and confuses your plants.
Make sure you have at lowest possible 3" of mulch, but not right up against your trees. Leave a few inches. Mulch will save even more marine.
How would you put in the picture whether...
Plants DO need an inch a wet of week to do well. In the Mid West, we start out the season running the systems 20 minutes a zone, three times a week. The best time to river is right at dusk or just at sunup. That minimizes the chance of evaporation into the heavens and the chance for fungus. Monitor the plants to see if the number of watering events own to be adjusted. Most every piece except the oak is probably in bed. When you fire up the zones surrounded by the beds, form sure that there is nil obstructing the flow of the marine to the back of the bed. If at hand is,you'll have to do some pruning or use extension pipes to incline the heads. Regarding the oak: it's probably within the turf. Keep an eye on it and if you see browning of the tips and it's not insects or disease, you may need to use a root feeder to obtain additional hose down to the roots. Move the feeder along the drip line and set off it in as needed.
