Last year we bought a new house in Phoenix (Climate Zone 2B, dry / hot). We are in the process of redoing the backyard.
We have a 2 story home that casts quite a bit of shade over the south portion of our lawn. Unfortunately, the sprinkler zones (2) were set up on the east and west.
As you can guess, we have overwatering in the shaded areas and dry spots in the full sun areas. Yikes!
We also have a crabgrass invasion that we plan to remedy by pulling out the existing lawn and replacing with a more shade tolerant St Augustine that only needs 4-5 hours of full summer sun. Our southern portion of the lawn will get this.
Ideally, we know that the sprinkler system should be N/S so we can regulate the zones appropriately, However, bids for the sprinkler redesign are high and it would be great if we could avoid it.
That said, does anyone know of reduced flow sprinkler heads or other solutions that might be a remedy for this problem?
Thanks in advance!
