Silver Leaf Philodendron is a easy-care plant. As an indoor plant, ensure good ventilation to aid recovery.

Unlike most plants, Silver Leaf Philodendron has natural resistance to Erwinia. Best treated with preventive measures rather than reactive treatment.

• ✓ Choose resistant or less-susceptible apple and pear varieties when possible.
• ✓ Plant trees and shrubs with good spacing and prune them yearly to maintain airflow and avoid dense, shaded canopies.
• ✓ Water plants at the base in the morning and keep foliage and flowers as dry as possible.
• ✓ Sterilize pruning tools before and during use and avoid pruning in wet weather.
• ✓ Use clean potting mix and containers and isolate new plants for 2–3 weeks before adding them to your collection.
• ✓ Avoid heavy nitrogen fertilization that encourages soft, lush growth.
• ✓ Remove and discard blighted twigs, mummified fruit, and fallen debris throughout the season.
• ✓ Manage insects that visit flowers or wounds, using non-chemical methods first, to reduce the spread of bacteria.
