Q.I planted a trumpet Vine last year and it is still just a woody stem. It is May 15 and I am in Zone 4. Will it come or should I pull
it? Will my Trumpet Vine come back?

Zone 4 is right on the edge of where they can survive. I don't know about your area but these last two winters have been particularly cold, and the summers cooler than average.
If it got cooler, or stayed cooler for longer in your area, then it is likely that it has died. You may need to replant.
If there is no growth by the end of May, then go ahead and try again with planting, but be sure to mulch a little extra as we move into a solar cooling period. It is likely to get too cold over winter again during these solar minimum cooling periods.
