Light. Full sun gives the most flowers.
Water. Keep the soil moist but well drained. Like other ixoras, it is moderately drought tolerant once established.
Soil and feeding. Ixora wants acidic soil. In alkaline soil, especially next to sidewalks and foundations, new leaves yellow from iron and manganese shortages. Plant away from concrete and treat yellowing with Manganese Sulfate.
Size. Grows to about 3 ft, a good height for a low hedge or border.
Pruning. Trim at any time of year. Constant shearing cuts down the flowers.
Problems to watch. Sooty mold on the leaves means aphids or scale; spray with Insecticidal Soap if natural enemies do not clear them. Purplish-red spots on older leaves mean a potassium and phosphorus shortage.
Good to know. It handles salty irrigation water but not direct ocean breezes. Frosts and freezes injure it. Each flower cluster lasts 6–8 weeks.
