Q: Please let me know how to get my trumpet vine to flower.
A: Blooming is affected by the age of the trumpetvine, available sunshine and the orientation of the stems. Young vines are less likely to bloom because they are producing non-blooming juvenile growth as the roots become established. Trumpetvine requires full sunshine to perform best. If the vine is climbing vertically, it is less likely to bloom than when proceeding in a horizontal direction. No fertilizer or chemical will “make” a plant flower. You just have to make it happy in its environment.
