Watering Needs
Proper watering is essential for the growth and health of Strophanthus courmontii Sacleux ex Franch. var. fallax Holmes. During the growing season, the plant should be watered regularly, and the soil should be kept moist but not waterlogged.

Additionally, pruning promotes airflow and light penetration, which helps prevent insect and disease problems.
Propagation of Strophanthus courmontii Sacleux ex Franch. var. fallax Holmes
Strophanthus courmontii Sacleux ex Franch. var. fallax Holmes can be propagated through several methods. The most common propagation methods for this plant are seeds, stem cuttings, and layering.
Propagation through Seeds
The seeds of Strophanthus courmontii Sacleux ex Franch. var. fallax Holmes are usually sown during the rainy season. The seeds should be planted in a well-draining soil mixture, and they should be covered with a thin layer of soil. The container should be kept in a warm and humid place until the seeds germinate.
The germination process can take quite a bit of time, ranging from a few weeks to several months. Once the seeds have germinated, the seedlings should be kept under light shade for a few weeks before they are transplanted into individual pots. The seedlings can be transplanted into the ground after they have grown to a suitable height and are robust enough to survive on their own.
Propagation through Stem Cuttings
Strophanthus courmontii Sacleux ex Franch. var. fallax Holmes can also be propagated through stem cuttings. Stem cuttings should be taken from semi-hardwood stems that are neither too young nor too old. The stem cuttings should be around 10-15 cm long and should have at least 2-3 leaves at the top.
The cuttings should be planted in a well-draining soil mixture and covered with a plastic bag or a transparent cover to maintain humidity. The container should be kept in a warm and bright place, but not under direct sunlight. The cuttings should start showing new growth within a few weeks. Once the cuttings have grown to a suitable size, they can be transplanted into individual pots or directly into the ground.
Propagation through Layering
Propagation through layering involves bending a low-lying branch of the plant towards the ground and covering a segment of it with soil or compost. The covered part of the branch should be kept moist and warm until roots develop from the covered section.
Once the roots have developed, the branch can be detached from the parent plant and transplanted into a new location. Layering can be done at any time of the year, although it is best to do it during the rainy season.
