The 2021 Open House is in the books! I had so much fun and I hope those that came out had fun as well. Our bloom percentage was very high - nearly every variety I have bloomed.
For the most part, bloom season has ended where I live (Central Virginia). So what do you do with the dead blooms and stalks? I recently recorded a video on the subject.

I typically let my leaves go wild until early July and then I trim them back about 8 inches. If I notice leaf spot, I trim right away (and treat if necessary). In the fall, I trim my leaves back to 6 inches.
As always, keeping a clean bed is important. Rhizomes should be uncovered where they/the plant can at least get 6 hours of sun. Old leaves and debris should be removed. And weeds - they're a struggle to keep up with, but weed removal is a must.
