Trumpet Vine Containment
I have a client with a large vigorous trumpet vine, that is sending root sprouts up in an adjacent garden and lawn. The vine is a effective seasonal cover for a two-story elevated deck, flowers nicely, and optimally would remain.
To contain the root sprouts I am considering excavating a 4' long/2' deep square trench 2' from the base of the vine, laying in landscape fabric, and backfilling. The work would be done in Spring '05.
The sprouts, separated from the parent plant, could then be plucked to eliminate. Parent plant could stand a reduction in vigor, and an increase in bloom (from the stress of root pruning).
Anybody have a better plan, or any objections to this?
