Why does your Trachelospermum jasminoides have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Star jasmine is sensitive to drought stress; when soil dries out completely, the plant cannot transport enough water to the furthest extremities, causing the tips to desiccate.
Excessive use of synthetic fertilizers leads to a buildup of mineral salts in the growing medium, which draws moisture out of the leaf tips via osmosis.
If the jasmine is in a container that is too small, the root mass prevents adequate water absorption, or if the soil is compacted, lack of oxygen causes tip dieback.
While usually presenting as spots, severe fungal infections in high-moisture environments can lead to necrotic tissue spreading to the leaf margins.
