During the summer, what is the best way to trim spent flowers on my trumpet vine in order to encourage more blooming throughout the season? I've only had one round of blooms for the past 4 summers, and suspect it is the way we are trimming. Do trumpet vines usually bloom once?
I live in zone 7-8. I have two trumpet vines that are only 5-6 inches tall, and it's already September. The smallest gets morning sun and afternoon shade. The bigger one, which I can actually tie to my trellis, gets morning shade and afternoon sun. They are so small. What am I doing wrong? What can I do to make them grow faster and bigger?
If you just planted them, they are likely growing roots first, then they will grow the foliage. If that is not the case, it may be your soil and the amount of sun they are getting. They actually like a poor soil and they prefer full sun. It can also take several years for the vine to get established.
My trumpet vine has green banana shaped pods on it about 6 inches in length. Is this normal? The plant is about 3 years old and produces a few flowers each year. Sorry, I have no photo.
Pods are normal. They will dry a brown color and fall off. Trumpet Vine spreads rapidly from the seeds in the pods and from underground roots. I planted a Trumpet Vine in Texas and it took over an entire flower bed, the fence and grew up the oak trees close by.
My husband hired someone to dig the bed down to three feet below ground level and fill it with new soil to get rid of the vine. The next spring the Trumpet Vine was back just as strong as ever. With Trumpet Vine you need to love it or leave it out of your garden.
