Key facts to know about ixora

Ixora will grow happily outdoors in US hardiness zones 9 - 11, 'doing well in the heavy humidity of the south,' says Tricia Hunt, plant expert and owner of Millstone Nursery. These shrubs 'are not winter hardy below 50 degrees,' Tricia continues, but this is not to say you cannot grow ixora if you live in a cooler zone.

While ixora thrives in tropical and subtropical climates, they can be grown as container plants and moved indoors in colder regions during the winter months. Doing so will add interest inside the home, with attractive leathery-green foliage popular with indoor gardeners.

Ixora are 'heavy bloomers,' Tricia says, 'making a nice filler for containers with dense, compact, deep-green foliage and bright blooms.'

Whichever you opt for, ixora plants require full sun exposure, growing best in situations with at least six hours of sunlight each day. Moving your ixora container to a sheltered, sunny spot is a good idea, especially in cooler zones.

'An added benefit of growing ixora,' Tricia says, 'is that this shrub is great for attracting hummingbirds and attracting butterflies,' which are all drawn to 'colorful blooms that remain on the plant for long periods of time.'

Ixora live plants are available to order online from Amazon.

How to grow ixora

• Soil: 'Ixora thrives in warm, tropical climates and prefers well-drained, acidic soil,' says Tatiana Anderson, plant expert and co-founder of Top Tropicals. Use a free-draining soil mix, adding perlite, sand or grit to improve the drainage. This is particularly important in containers to prevent waterlogging. If you live in an area with alkaline soil, consider conditioning your soil with something like this Soil Acidifier from Amazon, which will help your ixora shrub to grow well.
• Light: 'Optimal growth conditions are achieved when the plant is situated in an area receiving partial to full sunlight, fostering robust growth and prolific flowering,' says Tatiana. Whilst ixora will grow in areas of low light, planting in the shade will result in a lack of flowers. Remember that this plant is endemic to tropical regions, and thrives if grown in full sun.
• Watering: Established ixora plants 'demonstrate a noteworthy degree of drought resistance,' Tatiana continues. 'Adequate moisture is however vital for the health of your ixora shrub, but caution must be exercised to prevent waterlogged conditions,' Tatiana says. 'Excessive moisture can lead to leaf chlorosis,' with unattractive and yellowing foliage. Striking the right moisture balance will ensure that your shrub flourishes, 'allowing it to showcase its brilliant colors and lush foliage in a tropical garden setting.'
• Fertilizing: 'Feed ixora with a balanced, slow-release fertilizer during the growing season to promote healthy foliage and abundant flowering,' Tatiana says, using something like this slow-release feed from Walmart. Additionally, 'incorporate liquid fertilizers year-round if growing ixora in zones 9 - 11, to help sustain the overall health and vigor of your shrub.'
• Pruning: 'Ixora stand out as excellent hedge plants, owing to their bushy nature and the ability to produce an abundance of flowers on new growth,' Tatiana says. 'Whether you are cultivating a hedge or tending to a single, free-standing ixora plant, regular pruning is essential to prevent branches from becoming leggy.' Focus on the 'removal of dead or diseased branches, and shape the plant strategically to promote optimal air circulation,' Tatiana continues.
• Additional Notes: If you are growing ixora in a container in a cooler zone, remember to regularly water and feed throughout the growing season, and protect your tender shrub in fall. When the temperature begins to drop, move the container indoors until spring.
