Ixora plants should be grown in bright light, in soil that is consistently moist, but not muddy. Direct sunlight should be avoided during the summer months, and watering should be reduced during the winter months. Very high humidity is ideal, and the temperature should be over 60 degrees Fahrenheit if possible. If the temperature goes lower, it is important to protect the plant from cold drafts.
Ixora plants grow best in rich, peat-based soil with plenty of moisture. During the spring months, the plant should be given slow-release fertilizer pellets, or it can be given liquid fertilizer on a weekly basis during the growing season.
Moving the ixora plant or exposing it to cold temperatures can cause its leaves to drop. A lack of quality airflow can cause black sooty mold, which inhibits the plant's shine and growth. A greenhouse or conservatory is an ideal space for growing ixora.
Ixora plants that are allowed freedom to grow without trimming produce desirable blooms. Because ixora plants are so temperamental, they are often avoided by all but the most experienced gardeners. Rooting ixora plants is strenuous, and may require bottom heat and rooting hormone to be performed successfully. Ixora cuttings should be taken in the spring.
