This is the fifth year I have had my trumpet vine in, it has never flowered and does not look like it will flower this year. It is in a very sunny location, has water and the greenery is beautiful and lush. It does receive fertilizer when I fertilize the lawn, is that why it does not flower?
Thank you for your assistance.
It can take up to 10 years for a Trumpet Vine to bloom.
