Planted it two tears ago last spring. Vines (or runners- not sure of terminology!) out the wazoo. More of them than I can count, at least 10 feet long. But dadblastit, not one single flower ever. Thought since it grew like crazy it was doing well. Nice & green, no insect pests, looks great, but missing those sweet smelling little flowers. Any ideas?
I agree, could be it's not old enough-some things don't really get going until they've been in the ground ~3 yrs or so. But all the green growth makes me wonder if maybe it's also gotten a bit too much fertilizer? Too much nitrogen can stimulate green growth at the expense of blooms. I'd also look at how much sun it gets--too much shade could also prevent blooming.
