| I bet it'll recover. I once was given a trumpet vine root (rhizome? tuber?) in August.
August here is horrible.
I my own self go dormant. I planted it, &, as soon as I saw green emerge, I put cardboard shields on the western & southern sides to protect it. Just put sticks or stakes in the ground, 2 by 2, & slide the cardboard edgeways between each pair. xes are stakes & -s are cardboard. x x x x

x x x x (This is the best I can do for a diagram, I hope you get the idea!) Today it's a monster. A plant's *most* vulnerable times is when it's flowering:
it's expending all that energy to attract pollinators & assure the survival of its DNA, & it doesn't have energy to devote to repairing damage to itself. I've had my best luck moving things in late autumn, when they're dormant. They'll wake up next spring & not even realize they've been moved. Trumpet vines really are hardy;
my little orphan is huge & robust now, & I'll bet yours will be, too. |
