Best time to cut back Melianthus?
I'm looking for definitive advice as to when Melianthus should be cut back. Last year, I cut one back, and it returned beautifully, but now I can't remember what time of year I did this.
There are three in one of my client's gardens, and they're blooming gorgeously right now. However, the bottom leaves have mostly fallen off, and there is some new growth pushing through. My instinct says cut them back hard after they start to set seed. What say you?
