Allow soil surface to become slightly dry between watering. If kept indoors this will probably be daily. Plant doesn’t tolerate hard, cold water. In summer keep evenly damp, in winter water more sparingly.
Fertilizing:
Ixora are acid lovers. Feed monthly with a good quality water soluble fertilizer formulated for acid loving plants. March to august feed with a low dosage every 2 weeks.

As necessary, repot in spring with a mix of all purpose potting soil.
