At this mid-summer time of year, in particular, there are quite a few flowering plants that could use deadheading. For those of you not familiar with the term, in short, deadheading is the removal of old, spent flower heads. Typically these spent flower heads carry the seeds of the plant, and this is why you remove them (in most instances). This seed producing phase sends a signal to the plant that the flowering phase can now come to an end. In some plants you can actually encourage another round of flowering by removing the fading flowers; in affect telling the plant it needs to produce more flowers.
This is really not the case for hostas. I deadhead them because I feel they look like @#$% after their flowers fade. Frankly, I use hostas in my designs as foliage plants and rarely (if ever) consider the flowering aspect. Okay, maybe there’s 1 or 2 days in their flowering cycle where they look decent…I’ll give you that. But the next day I’m at them with my pruners (by-pass type work nice) snipping the spent flower stems at the base. Much better, right?
