When a tall phlox is done blooming, such as a David,
do I cut off the WHOLE Head ?
Or, do I go way down on the stem and cut it there.
I've read, to cut them off 2/3 of the way down. Is this correct?
I really want some rebloom! They are gorgeous.
|Your David Phlox will rebloom, but not on the same flower stems. It will develop new stems and the flowers will be produced on these stems. When the first flush of flowers is spent, cut the flowering stem down to the level of the rest of the foliage on the plant, or at least down to the first pair of leaves. This will remove the spent flowers and keep the stem from developing mildew. It will also encourage the development of two new stems where there was once only one. Hope this clarifies things for you.|
