Why won't my Trumpet plant bloom and do you trim it all down in the fall?

Answer 1

I have never trimed my trumpets and it took mine 2 1/2 yrs to bloom not sure why they take so long. I have had them now for 4 years and they are gorgeous.

Answer 2

Does it have enough sunlight? Or is it in partial shade? This article might assist you. I trimmed mine back in the fall and they bloomed profusely.
Trumpet Creeper, Campsis radicans, is a native vine found in nearly the entire breeding range of the Ruby-throated Hummingbird. Robust and aggressive, it is best planted at the base of a fence or tree where it can be trimmed back. With support, it can grow 20m high with a main vine nearly 15cm in diameter. Flowers occur on new growth each summer, from June through September in the Carolinas; the growing season is shorter to the north, slightly longer in the southern U.S. Trumpet Creeper blooms profusely in full sun, less so in partial shade.

Trumpet Creeper, also called "Cow-Itch" because it causes mild dermatitis in some people, can be purchased from native plant dealers; cultivars in yellow or deep red are available from garden nurseries. It may be transplanted from roadside areas where it is likely to be cut or sprayed by highway crews, or can be grown from its winged seeds (right), collected in early fall from a long brown pod. Although some folks consider this plant a weed, it is a VERY valuable native hummingbird flower.

I have heard that in certain areas it will take up to 7 yrs to bloom.Ihave an orange trumpet vine and it didnt bloom for about 4 yrs but now it looks really good

Answer 4

Many here in the south cut them down in the late fall and mulch them. They return in the spring. I have just planted 2 so I'm glad to know it might take a while to bloom.
