Does the cocoa shell mulch prevent flowers on morning glory vines?

my morning glory vine looks great but no flowers. The only differance this year is the addition of cocoa shell mulch.
Does the cocoa shell mulch prevent flowers on morning glory vines?
it is deffinately not the mulch. I would have to say that the cocoa mulch is useless as it washes away with rain, blows away with wind, and doesn't even smell very much.



It does have its place in the small sheltered perennial garden because it decomposes faster than bark does.



Ipomea species tend to need 6-8 hours of sun and like moist but well drained conditions. If it is not getting those condidtions it could have enough energy to get through the first year with flowers but not enough to come back the second with flowers.



Have you fertilized it? It could have depleted the soils phosphorus levels last year and need another shot to get it flowering again.
Reply:First, beware of that mulch, dogs find it delicious and it instantly kills them. As for the flowers, I'd say it was too cool and too dark.
Reply:was the mulch well rotted? if it was fresh the mulch will be taking nitrogen out of the soil to compose feed up the vines with some slow release fert
Reply:Idont know but it does kill dogs like chocolate
