Q.Late Winter/early Spring Prep For Rudbeckia Mass Planting?

Zone Walla Walla, WA area | Captain Eddie added on January 17, 2025 | Answered

I have a 24 ft X 3 ft bed which is a “mass planting” of Black Eyed Susans (Rudbeckia). There is a LOT of “old growth” left from the previous season – mostly dry, dead, standing stems. I’m thinking about a six inch high “hair cut” with a hedge trimmer to prepare for spring. Is this a passably workable idea?

Absolutely! Trimming death material is a good idea. By this time, they may have already re-seeded. It'll be a nice full area when it comes back.

Here is an article for more information on the flower:
