Miniature Sweet Flag

Tolerates a range from partial shade to full sun (6 or more hours of sun hitting the leaves per day. South-facing window, no obstructions. Under grow lights, keep them 4-8 inches away for 12-14 hours), though afternoon shade in hot conditions prevents leaf scorch. Variegated and golden-leaved cultivars need more light to maintain their color vibrancy - they go green and dull 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). Medium indirect light from an east or west window works well for most cultivars.

Prefers moderate to high humidity (60-80%. Group your plants together, set them on a pebble tray with water, or run a humidifier nearby). Indoors, supplement with a pebble tray or regular misting (note: misting does not actually raise humidity meaningfully. A pebble tray or humidifier is more effective). Low humidity causes leaf tip browning. It does well in terrariums where humidity stays naturally elevated.

Prefers fertile, moisture-retentive soil - the opposite of cactus mix. A standard potting mix with some loam or organic matter added works well. Clay, loam, and sandy soils all work as long as moisture stays consistent. pH between 5.5 and 6.5 is ideal.

Largely pest-free and deer-resistant. The main problem is leaf scorch from insufficient moisture or dry air. If leaf tips turn brown, water more and boost humidity before assuming disease. Root rot is theoretically possible but rare given how much water this plant tolerates.
