  1. Do you actually cut off just the spent blossom that is going to seed or the whole stock down to the leaves? I have read a few articles and this hasn’t been clear to me.

    1. Hi Kim, Great question! I personally wait until the stalk is done blooming and then cut it below the deadheads. I will try to get a picture of this. However, I think if it’s a slow bloomer, you can try removing just the spent blossom heads and see what happens. No harm in a little experiment! Hope this helps and best wishes with your garden!
