Aglaonema Pictum • Tricolor Care Guide

Care overview

Keep warm and avoid cold draughts. Consistent warmth and humidity support steady growth, but the root zone must remain aerated.

Light

Bright, indirect light. Avoid harsh direct sun, which can scorch the patterned foliage.

Watering

Water when the top 2–3 cm of substrate is dry. Keep lightly and evenly moist but never waterlogged.

Humidity

High humidity (60–80% preferred).

Temperature

20–28°C

Feeding and fertiliser

Feed every 4–6 weeks during active growth at quarter to half strength. Do not fertilise fresh divisions or newly rooted cuttings.

Potting mix

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

Propagation

Division or stem cuttings with at least one viable node.

Support

Naturally self-supporting. No climbing support is required.

Mature size

Mature indoor size varies with the species, support, light and root space. Expect gradual development into a fuller specimen rather than a fixed final size.

Semi-hydro suitability

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

Dormancy and winter growth

No true dormancy is normally required indoors. Growth may slow during the darker UK winter, so reduce watering and feeding in line with the plant's actual growth rate.

About this plant

Aglaonema Pictum 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.

Does Aglaonema Pictum go dormant in winter?

No true dormancy is normally required indoors. Growth may slow during the darker UK winter, so reduce watering and feeding in line with the plant's actual growth rate.

How large can Aglaonema Pictum grow indoors?

Mature indoor size varies with the species, support, light and root space. Expect gradual development into a fuller specimen rather than a fixed final size.

What is the most important care point for Aglaonema Pictum?

Keep warm and avoid cold draughts. Consistent warmth and humidity support steady growth, but the root zone must remain aerated.
