Was using feature(signature brand) 6-0-0 with micros and regulas 0-0-6 as a soil/foliar drench for ornamental shrubs as instructed by a local plant care expert. I was thinking of using some 46-0-0 at the same rate of N and using another micro package.

I didnt know you could even buy that anymore, I just use a cheap 10 10 10 or 8 8 8. If someone want something better I use the specefic food for the specific plant, like aziala fert, or rose fert etc.

Stopped doing that 20 years ago. It's a good way to grow unhealthy shrubs.

Even at high water volume and very low rates? 1/16 of a pound of N. I wanted to use up some remaining stock that i was using in previous lawn program combined with hydrex. It has to be useful, i want to mainly use it on privet.

Decaing mulch around the base of the hardwood ornamentals or any other tree is best... in fact I would dare say that all the N in adjacent lawns cause more rapid disease growth for plants than anything else... putting additional N right in the bed indicates a complete disregard of how hardwood is formed... aphids, mights and countless colonies of Fungi, just love watershoots and excessive growth...

Do most LCOs use ferts in those beds to ensure a market for insecticides/fungicides???

Most do this because they don't know any better.

Thanks for the reply's and totally agree on the use of cultural practices for plant health. I have always believed sometimes less is more. Turf in some respects follow the same trends caring for trees and shrubs. Above explains the many issue's improper use of N can have adverse effects on ornamentals. Turf is no exception and most guys go overboard increasing disease pressure(especially soil born). At that point fungicides are the only option. Cultural control on the east end of LI can be a tuff sell here when everybody expects perfection.
