1. Avoid reflected sunlight: white or light-colored pots last longer in strong reflective environments such as glass greenhouses. 2. Winter care: PP withstands about -20℃, but expanding ice can crack the pot — move pots indoors in severe frost.
3. Cleaning: wash with neutral detergent between seasons; avoid steel wool. 4. Drainage: check that roots do not block the bottom holes; add a leca layer if needed.
