Mosaic Virus on monstera deliciosa

What's Happening

True Mosaic Virus is systemic and rare in indoor houseplants. Most reported cases of "mosaic" on Monsteras are actually localized stippling from thrips/spider mites or nutrient deficiencies. Mosaic causes a distinct, irreversible quilted mottling that follows leaf veins and affects all subsequent growth.

How to Fix It

  1. 1

    Inspect undersides of leaves for tiny pests (thrips/mites) before concluding it is a virus.

  2. 2

    Quarantine the plant for 2 weeks. If the pattern spreads to new leaves in a distorted way, it may be viral.

  3. 3

    Check fertilizer history; iron or magnesium deficiency can cause similar chlorotic patterns.

How to Prevent It

Quarantine new plants. Sanitize pruning tools with alcohol between plants to prevent potential (though rare) viral transmission.
