Folks: I am adding 2-3 additional zones this year for my shrubbery. The beds are 6 and 8 feet deep. I tend to use Toro rotors in the lawn and Toro fixed sprays on risers behind my perennial beds. That said, I am willing to try other products (Hunter, et al). These shrub beds contain mostly evergreens, but there are tulips and such, between. I was thinking of using shrub bubblers at the base of the shrubs, but: 1. I cannot find them anymore, and 2. I am concerned that the tulips and such will not benefit. I could use pop-up sprays, but I am concerned that the shrubs will not get the deep watering that I am looking for. What do you all think?
