Q. I have two pink bower vines that have been in for a year. They flowered great last summer. The problem is that at the beginning of fall, leaves began to turn yellow and became hard. I fertilized and wonder if I may have overfertilized.
A> Glorybower or Clerodendrum need rich, loose soil with good drainage and plenty of water during the growing season. Most are evergreen with the exception of C. trichontomum (harlequin glorybower), which loses its leaves in fall. If yours is the evergreen kind, you may have overfertilized. Try flooding the soil repeatedly to remove excess amounts of salts that could burn the roots and turn the leaves a crispy brown. If yours is the deciduous kind, yellowing and eventually falling of leaves is normal.
