Why Did My Trumpet Vine Die?

Poor Structural Support

• It is essential that a trumpet vine has good support and a structure to twine and cling to. Without good support, the plant will not thrive. The structure could be something as basic as a chain link fence, a lattice trellis, rocks, a wooden retaining wall or even a tree, which actually is an elegant choice. As the plant flowers, it will provide a colorful contrast to the tree's foliage and flower, and give hummingbirds a nice stopover for a sip of nectar. Keep in mind that the structure should eventually be able to support the vine's growth, which at maturity can reach 30 to 40 feet.

Improper Site Selection

• Trumpet vines are sun lovers. They will tolerate partial sun, but they flower best when planted in a location that receives full sun. If the trumpet vine is planted in a marginally hardy area, such as USDA zone 4 (which is the lowest recommended zone for planting) provide the plant with some heat assistance such as against a stone or brick wall to protect it from the cold.

Soil Problems

• Another problem that could cause a trumpet vine to die is poor soil. Trumpet vines need soil that is rich and fertile. The plant's roots spread underground as "runners." This means the plant needs soil that is noncompacted and well draining, so the roots can grow strong and healthy. Amend the soil by adding compost, peat moss and manure to improve the drainage.

Over Watering

• It can be sad but true that you might be giving your trumpet vine too much love and attention by overwatering the plant. Trumpet vines love it when the soil is moist and hate it when their roots and "legs" are waterlogged. Test to see how the soil drains after a hard rain. If water collects, puddles and stands on the top of the soil for more than 2 inches, there is a good chance that the plant is getting far too much water. Move the plant to another location where the soil drains properly.

Stage of Maturity

• Last but not least, consider the stage of the development of your trumpet vine plant. There is an old adage that says "the first year it sleeps, the second it creeps and the third it leaps." This applies to trumpet vines. A plant that is not blooming may not be dead; it may just be dormant. A plant may or may not flower the first year. Be patient and don't give up on the plant by digging it up and discarding it. Your trumpet plant may come back the next season with a bounty of beautiful blooms.
