What is the likely cause for 26 year old 2 1/2' tall cypress shrubs to die successively from east to west, two months apart, in a Burbank, California location with morning shade and afternoon full direct sun. Would the cause (if disease) likely preclude replanting with the same species? Could this be irrigation related? What would be a recommended replacement option?

It may be that your plants have outlived their normal lifespans and that's why they are dying. If you've changed your watering practices (amount, frequency, source) over the past 3-4 months, it may have affected your shrubs, or there may be an insect infestation (you'll need to carefully check for mites, etc.). Aside from these factors, I can think of no reason for mature cypresses to die off. I think you can safely replant healthy cypresses in their places. Just make sure the drainage is adequate (to avoid root rot). Best wishes with your landscape!
