Troubleshooting
Asian Star Jasmine problems — and how to fix them
Asian Star Jasmine (Trachelospermum asiaticum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slow establishment
Spreads slowly in the first year or two. Plant at 30-45 cm intervals and water consistently; growth accelerates significantly once roots are established.
Scale insects
Soft brown or cottony scale can appear on older stems. Treat with horticultural oil in late winter before new growth emerges.
Frost dieback
Foliage may bronze or die back in hard frosts. Plants usually re-shoot from the base in spring. Mulch well to protect roots in colder areas.
Leaf yellowing
Iron chlorosis on alkaline soils causes interveinal yellowing. Apply chelated iron and check soil pH.
Aphids on new growth
Young shoots can attract aphid colonies in spring. Treat with a strong water jet or insecticidal soap spray.
