How to Grow Star Jasmine Vine (Trachelospermum jasminoides). This vine will do well in the southwest providing you follow some of the recommendations outlined in this article.
It is an exceptionally fast growing evergreen vine that will do well in partial shade. It does not mind the hot southwest weather but it will do better in shade. Do water consistently during the summer months as it is not a drought tolerant vine.
Where to plant it
Plant it in a shady spot if possible. Underneath a tree that gives filtered light will work wonders. Or on the east or north side of a wall, fence or dwelling. It will creep and crawl its limbs until it gets about 20ft. wide and about 10 ft. tall if planted as a stand-up vine or container. It will need a trellis or fence with support to climb.
Use it in a large container or espaliered vine. It does not mind being in a container. However, water more often for a better-looking plant during the summer, every other day will suffice. Be sure your pot has good drainage otherwise it will develop root rot. Fertilize with a good 20-20-20 analysis fertilizer. Once in spring, summer, and fall.
You can also use it as a ground-cover. Again, place it in a shady spot it will struggle if you plant it in full blazing hot sun especially as a ground-cover.
Does it have a flower
Yes, it does. And a very fragrant flower at that! It will bloom from mid-spring until the hot southwest sun comes around, usually around early June or so. After that, it is basically an evergreen plant.
Insects or diseases
Aphids, scale, and mites are a problem for Star Jasmine. They will suck the juice from the foliage and stems or produce small indentions into the leaves thus giving them an ugly appearance.
A good systemic insecticide will get rid of them quickly. Apply this insecticide at the first sight of these pests. The sooner you act the quicker they will be gone. Try neem oil as an organic substitute for insecticides. Insecticidal soap is also a good alternative but it does take numerous applications before it kills insects.
Fusarium wilt is a fungal disease that will destroy the Star Jasmine. But, it basically happens in places where there is lots of rainfall around the southwest this is not a big problem. As I mentioned earlier this plant does require lots of water and shady conditions. You will have to keep an eye on your watering systems. Leaks and overspray from sprinklers will promote fungal diseases. Use a good fungicide to remove Fusarium wilt. It will take numerous application before it is removed.
In regions where temperatures get below 20° farenheit the leaves will turn a purple then brown color this is due to the cold weather. It is best to wait until the last frost before trimming it back. It will regrow new foilage and your Star Jasmine will thrive and bloom again in mid-summer.
