Fiddle-Leaf Philodendron

bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well) is ideal. As a forest understory climber it tolerates some shade, but growth slows noticeably in low light (more than 8 feet from a window, or a north-facing room. A grow light 10-12 inches away works great if your windows are not cutting it). Avoid direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute), which causes yellowing and scorch marks on the leaves.

Prefers 50-70% humidity. Use a pebble tray, humidifier, or group it with other tropical plants to maintain moisture levels. Average household humidity in the low 40s is workable but not ideal.

Well-draining, slightly acidic loamy mix with a pH of 5-6. A blend of peat or coco coir, perlite, and pine bark works well. The pot must have drainage holes.

Spider mites, mealybugs, scale, and thrips are common pests. Root rot is the main disease risk. Bacterial soft rot and leaf spot can develop in overly wet conditions. The plant is sensitive to salt buildup from over-fertilizing.
