About Super King Ixora Red
Ixora casei 'Super King' · also called Super King Ixora Red, Super King Ixora · tropical
Super King Ixora Red is a large, vigorous tropical evergreen shrub bearing spectacular extra-large clusters of brilliant red flowers. It thrives in full sun, acidic well-drained soil, and high humidity—conditions it rewards with near year-round bloom. Non-toxic to pets. Ideal for tropical hedges, foundation plantings, and large containers.
Ideal humidity: 50–80%
Watch for — Iron chlorosis from alkaline soil: Yellow leaves with dark green veins (interveinal chlorosis) indicate iron deficiency caused by alkaline soil locking out iron uptake. Lower soil pH to 5.5–6.0 with elemental sulfur or acidifying fertiliser, and apply a chelated iron foliar spray for rapid correction.
The watering schedule, season by season
Super King Ixora Red likes a soak-then-partly-dry rhythm — let the top of the soil dry before watering again, and never leave it standing in water. The base rhythm for super king ixora red is every 5–7 days; maintain consistent moisture without waterlogging, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer: water when the top of the soil is dry to roughly a knuckle deep — typically every 5–7 days.
- Autumn (slowing down): Autumn: growth slows, so stretch the interval and let it dry a little more between waterings.
- Winter (rest / dormancy): Winter: water noticeably less — often half as often — because low light and dormancy slow water use right down.
Prefers consistently moist but well-drained soil. Allow the top 2–3 cm to dry slightly before watering again. Avoid prolonged dry spells, which cause bud drop and leaf scorch, and avoid waterlogging, which causes leaf spotting and chlorosis. Established shrubs are moderately drought-tolerant.

How to tell super king ixora red needs water
A calendar is the worst way to water super king ixora red. Check the plant and the soil instead — for this species, look for these signals in order:
- The top 2-3 cm of soil is dry to the touch (or a knuckle-deep finger test comes back dry).
- Lifting the pot, it feels distinctly light.
- Leaves droop slightly or lose a little of their gloss just before they truly need water.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering super king ixora red for a day is almost always safer than over-watering it.
Overwatering vs underwatering super king ixora red
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For super king ixora red specifically:
Signs you are overwatering
- Yellowing lower leaves and a pot that stays wet and heavy for days.
- Soft, brown, mushy stems or a sour soil smell — root rot.
- Fungus gnats breeding in permanently damp soil.
Signs you are underwatering
- Drooping, curling leaves with crispy brown edges that perk up after watering.
- The rootball shrinks away from the pot and water runs straight down the sides.
- Slow growth and a generally tired, washed-out look.
Watering super king ixora red on a fixed weekly calendar regardless of season is the most common mistake — in dim winter light the same routine drowns it. Check the soil, not the date.
Water quality notes
Tap water is generally fine for super king ixora red. If your water is very hard and you see brown leaf tips, switch to filtered or rainwater.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For super king ixora red, the levers that matter most are:
- More light and warmth speed drying; the brighter the spot, the shorter the real interval.
- Pot size and material matter — small terracotta pots dry far faster than large glazed or plastic ones.
- Lifting the pot to feel its weight is more reliable than any calendar for judging when to water.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of super king ixora red.
