I just got new sod (tall fescue) installed in my backyard today, approximately 700 sq ft. Concurrently, I installed the Rachio 3 that I ordered. I live in Southern California where the temperatures are supposed to range from the low 80s to the mid 90s during the next two weeks. I have fixed spray heads. The base of the soil is primarily decomposed granite with a few inches of compost/top soil that was mixed in using a rototiller (Rachio support said I should select “Sandy Loam” as my soil type). In order for the roots to set and build, the landscaper said the for the next two weeks, I should water 3 times a day for 4-mins each, every day. In week 3, 2 times a day for 4-mins eac, every day. Week 4, 1 time per day for 5-mins, every day. Week 5, 1 time per day for 5-mins every other day. Does this sound right? What is the best watering strategy for new tall fescue sod in hot and dry environment to set myself up for success in the future to a nice lawn? Will the short periods of watering allow deep root growth? I heard (and read on the internet) short watering could limit deep root growth, since the soil is not saturating 4"-6" deep. After reading the community pages, I understand the only way to configure as recommended by my landscaper is to set a fixed schedule. And then after the roots have set, I was planning on changing over to the flex daily schedule. Not sure about how to effectively transition from watering lightly every day schedule to something else without stressing the grass too much. Any suggestions?
