Cultivation Methods
Adenandra odoratissima Strid subsp. tenuis Strid grows naturally in rocky areas and stony slopes. To mimic its natural habitat, ensure that the soil is well-drained and not compacted. It flourishes in full sun exposure, but it also requires some shade during the hottest months of the year. When planting, ensure that the soil is rich in organic matter, and that you incorporate sand to improve drainage.
Watering Needs
Unsuitable watering is the most common cause of plant failure. To avoid this, water Adenandra odoratissima Strid subsp. tenuis Strid sparingly, and ensure that the soil is not soaking wet. During the dry spell, however, ensure that you water it sufficiently to avoid the soil from becoming too dry.
Fertilization

Propagation of Adenandra odoratissima Strid subsp. tenuis Strid
Adenandra odoratissima Strid subsp. tenuis Strid, also known as the Cape agathosma, can be propagated either by seeds or cuttings.
Propagation by seeds
The seeds of Adenandra odoratissima Strid subsp. tenuis Strid should be sown in a well-draining potting mix. The best time to sow the seeds is during the spring season.
The seeds require some light to germinate, so they should be covered with a thin layer of the potting mix. The pot should be placed in a warm, bright spot for optimal germination.
It is important to keep the soil moist but not waterlogged during the germination process. The seedlings will typically emerge within 1-2 weeks.
Propagation by cuttings
Adenandra odoratissima Strid subsp. tenuis Strid can also be propagated using softwood cuttings.
The cuttings should be taken from young, healthy shoots during the spring season. Make sure to use sharp, sterilized pruning shears to prevent damage to the plant.
The cuttings should be dipped in rooting hormone before being planted in a well-draining potting mix. It is important to keep the soil moist but not waterlogged during the rooting process.
The cuttings should be placed in a warm, bright spot, but protected from direct sunlight. The roots will typically form within 2-3 weeks.
Once the cuttings have rooted, they can be potted into individual containers and grown on until they are large enough to be transplanted into the garden.
