Star Jasmine in Extreme Heat: Why Full Sun Is Ideal and Soil Conditions Matter

Heat Tolerance

Star Jasmine (Trachelospermum jasminoides) thrives in 105°F. It’s a staple in California, Florida, Louisiana. Full sun is perfect.

Soil Requirements

• Slightly acidic.
• ZERO limestone (CaCO3) tolerance.
• NO salt tolerance (avoid coastal or saline water).
• Avoid synthetic fertilizers (urea-based) in pots—they degrade soil.

Planting

Deep cultivation (12+ inches) for roots. Do not disturb once established.

Pruning

Prune after flowering if needed, but the plant is happiest left alone in full sun with the right soil.
