Alocasia Zebrina
Alocasia zebrina
Through the year 🗓️
🍂 Fall now
Taper feeding and watering, and move it off cold glass as nights cool.
❄️ Winter
Rest it: water sparingly, and if it goes dormant, keep the corm barely damp and warm until spring.
🌱 Spring
Repot if truly crowded, check the corm for offsets to divide, and restart feeding as new stems rise.
☀️ Summer
Peak season: steady water in the heat, high humidity, and a weekly leaf-check for mites.
The details
Light & placement
- Light
- Bright indirect, and lots of it; this is a light-hungry alocasia, so a few hours of gentle morning sun are fine but harsh afternoon sun is not
- Ideal PPFD
- 200–400 µmol·m⁻²·s⁻¹
- Grow-light distance
- 10–16 in below LED
Water & feed
- Watering method
- Water when the top inch dries, then drain fully. It wants lightly moist but hates wet feet, and cold soggy soil rots the corm fast. A chunky mix makes this far easier to get right.
- Fertilizer
- Balanced feed at ½ strength, every 2–4 wks in spring–summer.
Home & habit
- Soil
- Chunky, airy aroid mix (bark + perlite + coco); pH 5.5–6.5
- Humidity
- High (60%+); crisps and invites mites below 50%
- Temperature
- 65–80 °F; keep above 60 °F
- Mature size
- 2–3 ft tall, arching striped stems
- Repotting
- Every 1–2 yrs in spring; it likes a snug pot and may sulk after disturbance
- Propagation
- Division of the offsets and corms at repotting; it doesn't grow from leaf or stem cuttings.
When something looks wrong
- Overwatering signs
- Yellowing leaves, mushy stem base, a soft rotting corm and sour soil
- Underwatering signs
- Drooping stems, curling leaf edges, crispy brown tips
- Common pests
- Spider mites are the number-one killer; also thrips and mealybugs
Common problems 🩺
The usual suspects when Alocasia Zebrina looks unhappy. Most houseplant trouble is watering or light, not disease — see all plant problems if you are not sure which plant is the culprit.
Fine webbing and stippled, dusty leaves
Likely cause
Spider mites. Alocasias are their favorite houseplant.
What to do
Rinse both sides of every leaf, raise humidity, and treat weekly until you see no new damage.
Leaves yellowing one after another
Likely cause
Overwatering, or a normal winter rest where it sheds down to a few leaves.
What to do
Water much less in winter. As long as the corm is firm, it will push new leaves in spring.
Stems flopping despite damp soil
Likely cause
Root rot from a mix that holds too much water.
What to do
Check the roots and repot into a chunky, fast-draining aroid mix.
