I have had a trumpet vine for about 4 yrs. that has never bloomed. I cut it back in the fall. Is that wrong? H

Um, there's neither a male or a female trumpet vine; they have both reproductive structures needed to produce fruit on the same plant.

Now, you can do one of two things:

1. Fertilize with a fertilizer high in phospherous. P is responsible for fruit and flower production. Look for a fertilizer higher in the middle number (like 7-9-5).

2. Plants will flower when stressed. They think their time is up, so they need to flower quickly to produce seed in order to continue their species. So, go around the base of your plant with a sharp spade and slice the roots. Don't dig anything up. Just go around in a circle around the main stem.

I think from what I have observed that the worse you treat a trumpet vine the better it blooms. For example I have seen it in sandy,junkie, worthless dirt. BLOOMING . I have seen it in abandon lots, and the yards of people who never fertilize their grass. Even if you could call it grass.

The dumpier the plot of land is the bigger the vine seems to be. That is personal observation only!
Reply:no trimming plants is actually necessary, but you have to know where to trim them as the same as rose plants and grape vines,as for not flowering, there may be a good reason for that all plants have , (you would be surprised) like male and female which means some are flowerbearing along with fruit and some do not flower or fruit,or may be it takes plants a longer time to actually come to its flower and fruit bearing, any way plants are beautiful with or with out flowers,and it helps in the enviorment,
Reply:First off I wouldnt cut it back too much I would move or tie the excess back rather than snipping it.Second is it a male or female vine?
