Anthurium Polyschistum

Anthurium polyschistum — a striking, climbing Anthurium with divided “palmate” leaves. It can be very rewarding if given the right conditions. If you like, I can also tailor the advice for Dubai’s climate.

Key Facts

• Habit: Climbing or vining, can grow terrestrially or epiphytically. 

• Leaves: Palmate (divided into several lobes or leaflets), somewhat delicate margins. 

Light

• Prefers bright, indirect light. East or north‐facing windows are ideal. If placed near harsher sun (south/west) use sheer curtains or place the plant a few feet back. 

• Too much direct sun → leaf burn (brown patches). Too little light → slow growth, smaller and less deeply lobed leaves. 

Watering

• Keep the soil slightly moist, but not soggy. Let the top ~2.5 cm (≈ 1 inch) or so of soil dry out before watering again. 

• Water thoroughly when watering; ensure excess water drains. Avoid letting roots sit in standing water

• In cooler/dormant periods, reduce frequency; in warm, bright or high‐evaporation conditions, you’ll need to water more often. 

Soil / Potting Mix

• Needs a well‐draining yet moisture‐retentive mix. Typical components: orchid bark, perlite or pumice, peat moss or coco coir, maybe some charcoal. 

• The mix should allow good aeration so roots don’t suffocate. 

Temperature & Humidity

• Ideal temperature around 18-27 °C (65-80°F). 

• High humidity is important: 60-80% or higher preferred. Dry air will lead to browning leaf edges, slow growth, difficulties with leaf emergence. 

Fertilization

• During growing season (spring & summer), fertilize with a balanced liquid fertilizer, diluted (often ~½ strength) every 4-6 weeks. 

• Cut back fertilizing in fall/winter when growth slows. 

Support & Growth

• Because it’s a climbing species, giving it support (moss pole, tree fern pole, trellis) helps encourage upward growth and larger leaves. 

• You can prune away damaged or old leaves to keep appearance neat; clean tools to avoid infections. 

Repotting

• Repot when the plant becomes root bound or when mix has degraded. Usually every 1-2 years. 

• Use fresh, chunky mix. Be gentle with roots; prune dead roots.
