I have owned this home for four years and have done MANY projects since buying including reclaiming the backyard from the weeds (the house sat empty for over a year prior). Anyway, in the front yard, previously I have just pulled weeds as much as I can around these shrubs I have but this year the shrubs have grown to a point where they need to be trimmed or something and the weeds are crazy. The shrubs are placed in a narrow "L" shaped strip between boulders lining the front yard with irrigation throughout. I want to have shrubs that are under control and NO WEEDS surrounding them. My problem is that I am unsure if it is okay to trim the shrubs at this point (they are currently flowering) and I am worried that they will just die. We get a lot of snow in the winter and the centers of the shrubs are beat down from heavy snow. The other thing is, I have no idea what kind of shrub they are. Can anyone give me advice?
