Alocasia Reginula • Ninja Care Guide

Care overview

Avoid overwatering. Likes stable warmth and humidity.

Light

Bright, indirect light (Avoid direct sun exposure)

Watering

Water when top inch of soil is dry, avoid waterlogging

Humidity

Moderate to high humidity (50–75%); stable warmth and airflow are more important than maintaining extreme humidity.

Temperature

18–28°C

Feeding and fertiliser

Feed every 2–4 weeks during active growth with House Plant Focus at quarter to half strength. Reduce or stop feeding when growth slows.

Potting mix

40% coarse orchid bark, 30% perlite, 20% potting mix, 10% worm castings

Propagation

Corms or cormels, rooted offsets, or rhizome division

Support

Self-supporting growth habit. A temporary stake may be used only if a petiole is unstable; climbing support is not required.

Mature size

Usually reaches around 40–120 cm indoors depending on the species or cultivar. Compact jewel types stay smaller, while larger upright forms may exceed 1.5 m in ideal conditions.

Semi-hydro suitability

Suitability depends on the plant, root condition and the chosen semi-hydro system.

Dormancy and winter growth

It has no required dormancy indoors, but Alocasia commonly slows or sheds leaves in cooler, darker conditions. Keep the rhizome warm and avoid overwatering while growth is reduced.

About this plant

Alocasia Reginula is held in the Snip & Sprout permanent collection and propagated in small batches when suitable parent growth is available.

Brown tips or edges

Likely cause

Can be linked to inconsistent watering, dry air, excess salts, unsuitable water quality, or leaf scorch.

What to do

Keep watering consistent, protect leaves from excessive direct sun and flush the growing medium when salt build-up is likely.

Pests

Likely cause

Thrips, spider mites, mealybugs and scale can occur on indoor aroids.

What to do

Inspect new growth, leaf undersides, petioles and stems regularly. Isolate affected plants and identify the pest before choosing a treatment.

Yellowing leaves

Likely cause

Can result from roots staying too wet or too dry, low light, cold stress, nutrient problems, or normal ageing of older leaves.

What to do

Check the growing medium and recent care before changing anything. Correct watering, light or temperature problems and remove only fully spent leaves.
