Answer: Trumpet vine, as most vines, can take a year or two to settle in and become fully rooted and established before it blooms its best. Trumpet vine does best in full sun all day, so a western exposure is adequate although not ideal. This is a plant that does well in average soil. Sometimes overfertilization can encourage excess foliage growth at the expense of flowers, so take care not to overfertilize it with nitrogen. Trumpet vine blooms on new growth of the season, so do not prune it during the summer. If you need to cut it back, do so in early spring. You can cut it back quite hard if necessary to control its size, most gardeners cut it back every spring. A spring pruning will encourage denser and more vigorous growth, so you may want to try that next spring. I hope it blooms nicely for you next summer!
