Trumpet vines are beautiful, sprawling plants that can spectacularly light up a wall or a fence. They’re also, unfortunately, very fast spreading and, in some places, considered invasive. This is, in part, due to the extensive trumpet vine root system. Keep reading to learn about trumpet vine root damage and how to go about removing trumpet vine roots.
How Deep are Trumpet Vine Roots?
Trumpet vines can reproduce by seed, but they rarely need to. This is because their roots are able to grow new shoots very easily. The trumpet vine root system grows deep and away from the vine. It will then surface far from the original and begin a new vine. To make matters worse, a section of vine that comes into contact with the soil will put down new roots which then, in turn, spread to who knows where. Even if your trumpet vine looks under control above ground, it may be spreading below.
Removing Trumpet Vine Roots
One of the best and easiest ways to prevent trumpet vine root damage is to keep the branches from reaching the ground and putting out new roots. Always keep your trumpet vine pruned so it grows up and out, never down to the ground. Also, be very careful when pruning that you pick up any stray pieces of vine that drop. A segment of vine as small as half of an inch can form roots and grow into its own vine. These segments will sprout as deep as 9 inches below ground, so tilling them won’t help. Be sure to pick them up and dispose of them. If new shoots appear from runners underground, cut them back as deep as you can. Even with the best of intentions, plants can become out of hand if not properly managed. In addition to pruning, make sure to keep these vines well away from your home and other structures that can be easily damaged.
