I have a trumpet vine that while growing very tall every year, has never flowered. We are in sandy soil, but I compost regularly and add mulch. Is there anything I can do to get this beautiful vine to flower? We attract butterflies, hummingbirds, etc. (We are in the Haliburton, Ontario region. )
The nitrogen to phosphorus ratio may be off. The soil may have an abundance of nitrogen, which would result in nice, healthy green growth but little to no blooms. Without the right amount of phosphorus, it will not bloom well. Bone meal is a great way to add phosphorus.
I have overwhelming trumpet vines that our taking over my yard. How do I kill them with out killing the grass? HELP, PLEASE.
My neighbors have a trumpet vine growing in their hedge that borders my property. The trumpet vine has grown through my sidewalk, driveway, into my dining room (through the basement wall) and I keep pulling it up in my planting area next to the hedge. What can I do to get rid of it? I have to patrol the area every week and spray and dig up the new shoots! HELP!
I read on one blog it gets 8 to10 feet and another 20 feet. I'm concerned about as a factor not cold down here in 9b southern Texas. Thanks, you guys are great!!
The thing about trumpet fines is that they will climb as high as they can find something to climb. Technically, they can go 40 feet even, if they have something to climb. In most gardens, their height is limited to a trellis, but if you plan on planting it, say, on the side of your house, you can eventually expect it to climb as high as your house.
Is it too early to dig up my Trumpet plant or do I wait until it stops blooming? I'm in NC.
Now is a good time. When you dig it up, it will lose its blooms, but this is a good season for transplanting.
How tall do trumpet vines grow? If I wanted one to grow up the side of my house, what kind of trellis or support would I need to construct? What is the best way to prune wisteria? My neighbor has a tiered wooden fence separating our properties and I have wisteria growing on my side and have it supported by a net and cable to even out the fenceline for privacy, but it is getting very heavy. Can I prune it agressively without killing it?
Trumpet vines can grow quite high and make a nice cover for a wall. We recommend that you build a trellis (plain slatted one is fine) for it to climb as its roots (which is uses to climb) can do damage to your walls.
You can prune wisteria very aggressively. This article will help with pruning: https://www.gardeningknowhow.com/ornamental/vines/wisteria/pruning-wisteria.htm
How can we propagate trumpet creeper? Is it from the seeds found inside the little prickly round balls on the plant?
