Mosaic Virus

Our analysis of 2 verified rescue cases across 2 plant species shows exactly what causes mosaic virus and the most effective fixes.

Quick Summary

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.

Most Effective Solutions

  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.
