About Pink Anthurium
Anthurium andraeanum 'Pink Champion' · also called Pink Flamingo Flower · flowering
Pink Anthurium is a compact evergreen aroid prized for its glossy, heart-shaped pink spathes that hold colour for weeks and rebloom almost year-round indoors. Grown for the waxy bract rather than the central spadix, it thrives in warm, humid, brightly lit rooms with airy, fast-draining soil and steady, never-soggy moisture.
Preferred mix: Coarse, airy, free-draining aroid mix
Watch for — Yellowing lower leaves: Usually overwatering and soggy roots. Let the mix dry more between waterings and confirm the pot drains freely.
Why pink anthurium needs this mix
Pink Anthurium is a climbing rainforest aroid — it wants a chunky, bark-heavy mix full of air pockets, not a dense soil that packs around its thick roots.
- In the wild pink anthurium climbs trees with thick, partly aerial roots that expect air as much as moisture — bark and perlite recreate that open structure.
- A chunky mix drains fast but the coir and compost still hold a steady reservoir between waterings, which suits its "moist then slightly dry" rhythm.
- The big air gaps stop the dense, fast-growing root mass from compacting and choking itself.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons pink anthurium struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain bagged compost packs tight around pink anthurium's thick roots, holds water in the centre and triggers the yellow-leaf-then-mushy-stem rot pattern.
- A fine, peaty mix with no bark leaves the roots gasping — growth slows and new leaves come out small and without fenestration.
- Too much moss or water-retaining additive keeps the core permanently wet and invites fungus gnats.
Using ordinary potting soil with no bark or perlite. Pink Anthurium needs roughly half its volume as chunky, airy material — that single change fixes most "mystery decline".
pH — does it matter for pink anthurium?
Pink Anthurium prefers a slightly acidic mix, around pH 5.5-6.5, which a peat-free compost-and-bark blend lands on naturally. It is not fussy enough to need testing in practice.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged "aroid mix" is now widely sold and is a fine shortcut for pink anthurium, but check it actually contains visible bark and perlite — many are just rebranded compost. Mixing your own from the ratio above guarantees the structure.
Drainage and the pot
Any pot with a drainage hole works because the chunky mix does the draining. A pot only a little larger than the rootball avoids a wet, unused core; add a moss pole and the climbing roots will thank you.
Bark breaks down over time, so refresh the mix for pink anthurium every 12-18 months even if the pot size is still fine — spent, sludgy bark is a common hidden cause of decline. When the time comes, our repotting guide for pink anthurium covers the timing and technique step by step.
