Philodendron Hastatum “Silver Sword”

Watering needs change seasonally: – Spring and Summer: Water more frequently as the plant is actively growing. – Fall: Reduce watering as growth slows. – Winter: Water sparingly, only when the soil is dry several inches down. Well draining soil – slightly acidic Water-soluble fertilizer with an NPK ratio of 10-10-10 or 5-5-5 is suitable.  Optimal schedule: If fertilizing, do so in early spring as new growth begins, and optionally again in mid-summer. Avoid fertilizing in late summer or fall to prevent encouraging tender new growth before winter.
