I had a one cane Westerland two years ago. I dug out from under it and buried the lower portion of the one cane. Evidently it went own root, because several new canes grew from below the surface. I now have a bush with several canes.

Westerland is a vigorous rose. I'd keep it. Instead of replanting it, you can also add more soil to bury the bud union. This is actually preferred if you have drainage issues like we do.

Cut off the dead canes flush with the bud union - the lumpy part from which the canes are growing at the base - don't leave any "stumps". Make sure that there are no weeds or other plants growing within 18 inches of the base of the rose. Then, I would get some rose food at the nursery, and just follow the directions to feed it (make sure it is just fertilizer - no poisons for bugs). Assuming it is growing in the sun, it should start making more growth, and eventually it will produce more canes from the base. You will have to be patient and wait, but it will.

And be patient. Climbers take 3 or more years to mature and climb. This being only a second year plant may not do a lot this season but should do much better next year.

Sometimes I have been known to cut off all BUT one branch of a climber like that, and made it into a rose tree. You do that by staking or tipping the whole plant so your one branch goes where you want it to go, and then removing all thorns and growth shoots below where you want the crown of the tree to form.

It does work, but takes 3-4 years of doing that to get a "tree" looking plant. I've only tried it with climbers.

Thanks very much for all the advice! I've reburied, fed, and mulched it today, and will be patient...
