karri_sue - If the species of perennial MG you have is Ipomoea indica,these plants are known to like full sun,so if the plant isn't getting enough sun to flower,they will produce alot of vegetative growth,but will not flower...sometimes using mirrors and other reflective materilas can help to increase the amount of reflected light to the plant...many beach plants are dependant on the light reflected back up onto the plant by the sand...

Sometimes high Nitrogen levels can impair early flowering,but the fish emulsion should not have excessive nitrogen...sometimes using a bloom boosting macronutrient like Phosphorus(which will not cause excessive leaves growth or impair flowering) can stimulate blooming...if you can't do anything to give the plant more sun,perhaps some of the other B-vitamin based bloom boosters may help...

Here is a suggestion for an experiment to try and diagnose the problem...

Root a cutting from the main plant and place the rooted cutting into a container where it will receive the most sun you can give it...if it blooms,then you will know that the main plant not blooming hasn't much to do with the soil conditions,but is related to amount of sunlight being received...

Hope you can figure out a way to get some blooms...

TTY,...

Ron,
Thanks for all the info! I think you are right, I don't think it gets enough sun. I'll have to find a new spot and move it in the fall. In the meantime I did buy a bloom booster so I'll see if that works.
Thanks again,
Karri
