About Alocasia Reversa

Alocasia reversa · also called reverse alocasia, Western Australian alocasia · tropical

Alocasia reversa is a compact jewel alocasia from limestone forests of Sarawak, Borneo, named for its reversed colour pattern: deep blue-green leaf centres and veins framed by shimmering silvery-green margins. Small and slow-growing, it needs warmth, bright filtered light, high humidity, and an airy, mineral-rich mix, rewarding patient growers with striking metallic foliage.

Preferred mix: Airy, mineral-rich aroid mix

Watch for — Root rot from overwatering: The small rhizome rots fast in soggy or dense soil. Use a very airy, mineral-rich mix, water only when the top few centimetres dry, and ensure sharp drainage.

Why alocasia reversa needs this mix

Alocasia Reversa 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.

For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.

What goes wrong with the wrong mix

The wrong soil is one of the most common reasons alocasia reversa struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:

Using ordinary potting soil with no bark or perlite. Alocasia Reversa needs roughly half its volume as chunky, airy material — that single change fixes most "mystery decline".

pH — does it matter for alocasia reversa?

Alocasia Reversa 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 alocasia reversa, 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 alocasia reversa 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 alocasia reversa covers the timing and technique step by step.

2 parts peat-free houseplant compost or coco coir : 2 parts orchid bark (fine-medium) : 1 part perlite : 1 part horticultural charcoal. In the wild alocasia reversa climbs trees with thick, partly aerial roots that expect air as much as moisture — bark and perlite recreate that open structure.

Can I use normal potting soil for alocasia reversa?

Plain bagged compost packs tight around alocasia reversa's thick roots, holds water in the centre and triggers the yellow-leaf-then-mushy-stem rot pattern. Bagged "aroid mix" is now widely sold and is a fine shortcut for alocasia reversa, but check it actually contains visible bark and perlite — many are just rebranded compost. Mixing your own from the ratio above guarantees the structure.
