Title: poor blooming on (non-native) plumbago
Answered by: Guy Thompson

QUESTION:

I recently purchased several blue Plumbago plants that were covered in blooms. We planted them in our front beds that receive about 5 hours of morning sun then afternoon shade. I have watered them every other day to get them established and the plants look very healthy but all the blooms are gone and have not rebloomed at all after the first week of being in the beds. What do I need to do and do they need some bloom fertilizer? We live in Florida where Plumbago is often used in flower beds.

ANSWER:

There are some U.S. native species of plumbago, e. g., Plumbago scandens (Doctorbush), but I expect you have a different and more common species, Plumbago ariculata, which is a native of South Africa.  Mr. Smarty Plants doesn't keep info on non-native plants, so I can't be of much help.  However, I am sympathetic since I have had a similar problem with P. ariculata myself. This plant blooms on the current year's growth, so trimming back the branches, and particularly the spent flower heads, should encourage a new round of growth and new flowers.  Now that your plants are established, cut back on the water. They are drought-resistant, and too much water will promote vegetative growth in preference to flowers. If you fertilize, give them a high phosphorus fertilizer.  Good luck!
