There are over 400 species of Ixora, a tropical flowering shrub native to Asia. Planted outdoors, Ixora makes a lovely hedge and is also used in borders and containers. This slow growing plant can grow to 15 feet in height 10 feed in width. There are dwarf varieties available. Because Ixora is a tropical plant it does best in USDA hardiness zones 10 and 11.
Give the Ixora full sun, lots of warmth and humidity. Plant it in a soil mixture that is high in acid. You can achieve this by adding a 1 to 2 inch layer of sphagnum peat into the top 10 inches of the soil prior to planting.
Water the Ixora well and then allow the soil to dry out somewhat before watering again.
Fertilize the Ixora once a month with a 10-10-6 fertilizer or any fertilizer meant for azaleas, another acid-loving plant. In early spring to late mid-summer, dilute the fertilizer to half strength and apply every two weeks.
Cut 2 or 3 leaves just beneath the flower to encourage Ixora to grow fuller and bloom more. Pruning can be done anytime.
