About Colocasia Burgundy Stem
Colocasia esculenta 'Burgundy Stem' · also called Burgundy Stem taro, burgundy elephant ear · tropical
Colocasia esculenta 'Burgundy Stem' is a bold elephant ear with large heart-shaped green leaves on deep wine-red petioles. Unlike alocasias, it is a thirsty bog plant that loves constant moisture, full sun to part shade, rich soil and heat. Vigorous in summer, it dies back in cold. Toxic to cats and dogs like all Colocasia.
Preferred mix: Rich, heavy, moisture-retentive soil
Why colocasia burgundy stem needs this mix
Colocasia Burgundy Stem hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Colocasia Burgundy Stem comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons colocasia burgundy stem struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for colocasia burgundy stem — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets colocasia burgundy stem dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for colocasia burgundy stem?
Colocasia Burgundy Stem prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
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
A good peat-free houseplant compost works for colocasia burgundy stem straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh colocasia burgundy stem's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for colocasia burgundy stem covers the timing and technique step by step.
