Should I move my Trumpet vine that won’t grow?

Question

I have had a trumpet vine for 2 years now. It is in a very sunny spot with support. The soil is terrible though but I thought it didn’t matter. When I planted it I added quite a bit of compost to the soil to give it a start since my soil is nothing but dry dead sand.
It grew a little the first year and bloomed quite well. By a little I mean it grew about a foot. So it is now about 2 feet tall only.
I am worried that I should amend the soil around it or even move it. I know they are tough and fast growers so I am worried. Thanks …

If it is indeed the big orange-flowered trumpet vine (Campsis radicans) and not trumpet honeysuckle (which is slow to take off) it should be taller by now. It is a vigorous grower, and if not contained, will sucker underground and come up all over the place.

You didn't say where you got it, but it's possible it is not mature. Usually people have problems with it blooming, but you say yours bloomed.

The conditions you provide seem ample. I would say try pruning the vines back about half to encourage growth. In fact in the spring, you can cut them completely back.
