Can ixora be grown indoors?
Ixora can be grown indoors, but it is not an easy houseplant. It is a tropical evergreen shrub from Asia, widely grown outdoors in warm climates, where it flowers heavily in clusters of small red, orange, yellow or pink blooms. Indoors it needs a lot of light, steady warmth and humid air, and it reacts quickly to changes. Smaller or dwarf varieties are generally the better choice for pots.
If you have a bright, warm room and you are comfortable with some fuss, ixora is worth trying. If you want a forgiving plant, one of the other plants in the flowering houseplants group may suit you better.
Light
Ixora wants bright light, including some direct sun, to grow well and produce flowers. A south- or west-facing window is typical, or a spot with several hours of bright light. A grow light can help in winter. In low light, plants tend to stretch, thin out and stop flowering.
Watering, water quality and soil
Ixora prefers soil that stays evenly moist but never waterlogged. Let the very top of the mix dry slightly, then water thoroughly and discard the excess. Both drought and soggy mix can cause leaf drop.
Ixora likes acidic soil. A mix designed for acid-loving plants, or a peat-based or similar mix with added drainage material such as perlite or bark, is commonly recommended. In alkaline soil or with hard tap water, the leaves can turn yellow between the veins, a problem called chlorosis, which is often related to the plant being unable to take up iron. Using rainwater, filtered water or other low-mineral water, and an acid-loving plant fertilizer, may help.
Temperature and humidity
This is where many indoor ixora struggle. The plant likes consistently warm temperatures and dislikes cold drafts, air conditioning blasts and sudden changes. Dry air from winter heating can cause leaf and bud drop. A humidifier, grouping plants, or a pebble tray (with the pot kept above the water) can help. Keep the plant away from heaters, vents and cold glass.
Feeding and pruning
Feed during the growing season with a diluted fertilizer formulated for acid-loving or flowering plants, following the label. Reduce feeding when growth slows in cooler, darker months.
Prune lightly after a flush of flowers to keep the plant compact and encourage new growth, since blooms form at the stem tips. Avoid heavy cutting in the cool months. Cuttings can be rooted, but it requires warmth and humidity and is slower than with many common houseplants.
Do ixora bloom all year?
In warm, bright, humid conditions, ixora can bloom through much of the year, sometimes in waves rather than continuously. Indoors, most plants bloom less, and flowering often drops off in winter. Low light, dry air, inconsistent watering, and moving the plant around are all common reasons for few or no blooms.
How long does an ixora plant live?
Outdoors in a suitable climate, ixora can be a long-lived shrub. Potted plants indoors vary a lot. With good conditions and repotting when needed, a plant may last several years, but no specific number can be promised, since many indoor plants decline early because of dry air, low light or overwatering. Treat it as a plant that needs regular attention.
Common problems
- Yellowing leaves with green veins: Often alkaline soil or water, or iron deficiency. Check soil acidity and water quality.
- Leaf and bud drop: Dry air, cold drafts, being moved, or irregular watering.
- No flowers: Not enough light, over-pruning, or too little feeding.
- Brown leaf tips: Low humidity, salt build-up, or underwatering.
- Pests: Spider mites, mealybugs, aphids and scale can show up on weak plants. Isolate the plant and follow label directions for treatment.
Pets and children
Safety information on ixora is not consistent from source to source. Because the plant’s toxicity to pets and people is not clearly established, treat ixora as not for eating. Keep it away from curious pets and small children, and call your veterinarian, doctor or poison control service if any part is chewed or swallowed. For a plant more often described as non-toxic, see the goldfish plant care guide.
