What is the proper way to deadhead starfire phlox and red flame phlox?
Both of these varieties have blooms on single stems. Do I just snip off the spent bloom right at the top of the stem, leaving the stem? New buds are not presently visible!
Cut off spent flower clusters as soon as the flowers begin to wither with a pair of small shears.
Cut off the entire flower spike once all the buds have bloomed and there are no new buds forming along the stem.
