Question: Why doesn’t my Madame Galen trumpetcreeper doesn’t flower very heavily, when others in the neighborhood are beautiful every summer.

Answer: That can be caused by several factors. Foremost, it may be getting too much nitrogen fertilizer, particularly if it’s adjacent to turf. Morning glories and trumpetcreepers are notorious for staying vegetative when they receive lawn-type fertilizers. It also needs to be in full or nearly full sunlight, and hopefully you won’t be pruning it very heavily. If you cut it way back during the winter, you can expect really strong vegetative regrowth the following spring and summer. That comes at the expense of reproductive (flowering) growth.
