A plant sold as African jasmine should not automatically receive true jasmine care. Ask for its botanical name and assess the conditions around the actual pot.
Clarify what African jasmine means on the label
African jasmine is a common name used for different ornamental plants, including plants that are not Jasminum. Obtain a botanical identification before using a jasmine pruning schedule, a fixed winter limit or a promise about fragrance.
Establish a suitable root environment
Choose an appropriate draining medium once the plant is identified and inspect the existing root ball. Do not automatically add fermented household materials, concentrated fertilizer or iron simply because the common name suggests an acid-loving shrub.
Match light and water to observed growth
Provide useful light with gradual acclimation from nursery shelter. Check root-zone moisture before watering, especially after moving indoors or changing pot size. Yellow leaves can follow several problems; they do not by themselves diagnose an iron shortage.
Shape and repot for a purpose
Remove damaged material carefully and delay major pruning until the flowering habit is understood. Repot for congestion or deteriorated medium rather than on an inflexible annual schedule. A stressed plant needs its conditions checked before more demanding work is added.
