Pruning on pothos
What's Happening
Improper leaf removal technique spreads pathogens by crushing infected tissue and releasing spores/bacteria onto healthy foliage and soil. Using non-sterilized tools transfers pathogens between plants. Removing leaves at the wrong angle leaves stubs that decay and become secondary infection sites. Incomplete removal leaves pathogen reservoirs that reinfect new growth.
How to Fix It
- 1
Sterilize shears with 70% isopropyl alcohol before touching plant and between EACH cut on different plants
- 2
Choose dry midday (10am-2pm) for pruning when humidity is lowest and pathogens are least active
- 3
Cut petiole at 45-degree angle flush with main stem; do not leave stub that can decay
- 4
Grasp removed leaf with gloved hand or tool; place directly in sealed plastic bag without touching other foliage
- 5
Dispose of infected tissue in outdoor trash or sealed bag; never add to compost or leave near plants
How to Prevent It
Sterilize pruners with 70% isopropyl alcohol before AND after each plant contact. Remove leaves during dry midday hours when pathogens are less active. Cut at 45-degree angle close to stem without leaving stub. Place removed tissue immediately in sealed bag; never compost infected material.
