Reader Question

My Anthurium hasn't bloomed in over 4 weeks. It has constant leaf growth, but leaves look rusted, feel thick and weird. What's wrong?

Diagnosis: Spider Mite Infestation

Based on the photos, your Anthurium likely has spider mites — tiny pests that thrive in dry indoor air and cause stippling, bronzing, and thickened leaves. They're often invisible to the naked eye but leave fine webbing.

Effective Treatment: Insecticidal Soap Spray

1. Mix plain water with a squirt of liquid dish soap in a spray bottle.
2. Thoroughly spray all leaf surfaces and stems until dripping wet.
3. Repeat in 5–7 days if needed. One thorough application often suffices.

This messy but effective method smothers mites without harsh chemicals. Increase humidity around the plant to discourage recurrence.

Prevention

• Mist foliage regularly or use a pebble tray.
• Inspect new plants before introducing them.
• Keep plants well-watered — drought-stressed plants attract mites.
