Yes I’ve seen good results with what I call a delayed dormant application. My mixes include a micronized soft rock, humic and fulvic blend, zinc, manganese, cobalt, molybdenum, boron and silica. I’ve also been adding a thyme oil product to control pseudomonas syringae. The application has shown good results with frost resilience. I will not add urea until my bloom application, but maybe I should consider using urea on both applications?
