watering
Blue trumpet vine (Thunbergia grandiflora) needs to be watered frequently, about once a week or more during the hottest part of the summer, and less frequently during autumn and winter. When it's necessary to provide more water, it should be done in the morning and provided with enough water to reach the bottom of the root zone. The plant prefers being kept evenly moist, so check the soil moisture often and water accordingly. Overwatering is a common cause of problems, so be sure to let the soil dry out a bit between waterings.
sunlight
Thunbergia grandiflora, or blue trumpet vine, prefers full sun to part shade. The plant likes plenty of bright, direct sunlight, especially in the morning, as it helps to encourage strong and healthy growth. The blue trumpet vine also develops more flowers when it receives direct sunlight for a majority of the day. Though it can tolerate some prolonged shade, be sure that your blue trumpet vine gets at least 4-6 hours sunlight every day to ensure the best results.
pruning
Blue trumpet vine should be pruned in the early spring, just as new growth starts to emerge. Prune out any old or damaged stems, then focus on shaping the vine. Remove up to 1/3 of the length of the stems, cutting a few inches above a leaf node. The top of the vine should be kept to a manageable height, usually no more than 2-3 metres. Pruning in the early spring will encourage branching and more flowers for the season.
