Goldfinches descend on my Perovskia as late as April, so I leave it until the new growth is already well on the way.
@eugeneparnell My one beef with leaving wind-carried seedpods up, like goldenrod, asters, or white snakeroot, is it's impossible to walk through my garden without getting covered in seeds right now.
Presumably this will be solved by the wind carrying the seeds away eventually, or if I find the time to save the seeds, but until then garden maintenance is a challenge. I don't want to just ignore the seeds, because then they'll be stuck to my clothes and get vacuumed up or laundered in my house.
Which makes for an unhappy dilemma between standing wildlife habitat versus wildfire mitigation, which my region has to negotiate on the regular.
Not too long ago, we lost <1K homes, because a wildfire just blasted down a creekbed, which residents had been advised to leave unmowed for wildlife support. 😩
Yeah, definitely one for the Lessons Learned file.
An additonal layer is that we are also prone to high winds. I mean, like realy f'n high winds. (Think the LA Santa Anna wildfires.) I learned the term "ember storm." Which I would have happily gone my whole life not knowing.
