Lighting
Philodendron silver swords thrive under bright indirect light.
While some direct sunlight is permitted, it's not recommended to give your silver sword plant too much direct light as this can negatively affect the leaves of the plant.
Water
In general, philodendrons are not fussy when it comes to a water schedule, and the silver sword is no different. The silver sword plant enjoys a soil that is lightly moist.
Soil
An aroid potting mix would be the most suitable option for your philodendron. Aroid mixes provide the best drainage and water retention that your philodendron needs to thrive.
