Anthurium Care: Sandy Mix, Dry-Down Watering, High Humidity

Fixing Dark Spots and Leaf Decline

Anthuriums need a specific root environment: airy, moist but never soggy. The peat-based mix they’re sold in stays too wet.

Immediate Repot

1. Remove plant, gently shake off most peat mix.
2. Repot in 1:1 play sand + peat-based potting soil.
3. Water only when top 2 inches of mix are dry.

Ongoing Needs

• Light: Bright, indirect. No direct sun.
• Humidity: High (60%+). Use humidifier or pebble tray.
• Temp: 65–80°F (18–27°C).
• Fertilizer: Balanced, dilute, monthly spring–fall.
• Winter rest: Slightly drier, cooler, no fertilizer.

On Your Current Issues

• Dark, dry spots = likely sunburn or fungal from wet leaves. Keep foliage dry.
• Remove fertilizer spikes—they burn roots in peat.
• Blooms are a good sign; fix the root zone and the plant will thrive.
