Aphids on philodendron
What's Happening
Aphids cluster on tender new growth and unfurled leaves of philodendrons, piercing soft tissue to extract sap. Their rapid reproduction through parthenogenesis creates population explosions within days. On philodendrons, they target the delicate emerging leaves which lack the thick cuticle of mature foliage. The succulent new growth provides ideal feeding conditions.
How to Fix It
- 1
Rinse plant with strong water spray to dislodge aphids from leaves and stems
- 2
Apply diluted neem oil slightly more concentrated than label directions for soft-bodied pests
- 3
Spray affected areas thoroughly, leave for 15 minutes contact time, then rinse off residue
- 4
Move plant to shady location during treatment to prevent leaf burn on sensitive new growth
- 5
Reapply neem treatment 1-2 times per week until all aphids are eradicated
- 6
Gradually re-acclimate to brighter light over 1-2 weeks once pest-free
How to Prevent It
Inspect new plants thoroughly before introducing to collection; maintain moderate humidity 60-80%; ensure bright indirect light without direct sun scorch; quarantine new acquisitions for 2-4 weeks; inspect new unfurled leaves weekly.
