Stromanthe Triostar Care Guide

Stromanthe thalia

Also known as: Stromanthe, Triostar

Watering

Summer

Every 8 days

Winter

Every 12 days

Keep soil evenly moist but never waterlogged. These plants hate drying out completely.

Light

Medium indirect

A few feet from a window, or north-facing

Humidity

60-80%

High humidity lover. Consider a humidifier or pebble tray.

Pet & Child Safety

Safe for pets and children

Pot & Soil

Likes a cozy pot. Needs well-draining but moisture-retentive mix - peat with perlite.

Pot-size watering

The 8-12 day range is a starting point. A 5cm pot can need checking much sooner, while a 22cm pot may stay moist for longer. Keep the soil lightly moist, but check below the surface so a large pot is not staying soggy.

Prefers snug roots

This plant usually prefers a snug root zone. Size up only when roots are circling, the plant dries out much faster than usual, or growth has clearly stalled.

Soil refresh

Refresh tired or compacted soil yearly, because moisture-loving plants still need air around the roots, not dense wet mix.

💡

Good to Know

Pink, white, and green variegation. Stunning but demanding.
