Pinstripe Calathea

Growing & care

• Light: medium to bright indirect — never direct sun, which bleaches the striping. East-facing windows or set back from south light.
• Water: keep evenly moist with distilled, rain, or aquarium water. Calathea is famously fussy about tap-water chemicals — brown crispy leaf edges almost always trace to fluoride or chloride.
• Soil: rich, humus-rich potting mix that retains moisture but drains; add coco coir or peat for water retention.
• Humidity: 60%+ required. Below 50% causes brown leaf edges fast. A humidifier nearby is more reliable than misting.
• Temperature: 65–80°F. Avoid drafts and cold windowsills below 60°F.
• Fertilizer: monthly during spring/summer at quarter to half strength; skip in winter.

Propagation

Divide established clumps in spring when repotting. Lift the entire root mass, locate natural divisions in the rhizomes, and separate with a sharp clean knife. Each division needs at least 2–3 stems with attached roots. Pot up immediately and keep extra humid for 2 weeks while the divisions recover.

Common problems

Brown crispy leaf edges = tap-water chemicals or low humidity. Curled inward leaves = under-watering or too cold. Faded striping = too much light. Sudden mass leaf decline often follows a single dry-out — calathea does not bounce back like a peace lily. Spider mites colonize dry-air rooms in winter; raise humidity and shower the plant. Confirmed non-toxic to dogs and cats per ASPCA listings — one of the safest large-leaved tropicals for pet households.
