Calathea Illustris

• Native to South American rainforests where it grows as an understory plant in filtered light conditions.
• Features distinctive patterned leaves that fold upward at night, earning the nickname 'prayer plant family member'.
• Belongs to the Marantaceae family known for their decorative foliage and air-purifying qualities indoors.
• Loved by plant collectors for its stunning leaf patterns and relatively compact growth habit.
• Produces small white flowers occasionally, though it's primarily grown for its spectacular foliage display.

• Water when top 2cm of soil feels dry, typically weekly in growing season and less frequently in winter.
• Position in bright, indirect light such as near east or north-facing windows, avoiding direct afternoon sun.
• Use well-draining potting mix with peat or coco coir for moisture retention and good drainage.
• Feed with diluted liquid fertiliser monthly during spring and summer growth periods.
• No pruning required except removing damaged or yellowing leaves at the base of stems.
• Maintain humidity levels above 50% using pebble trays, humidifiers, or grouping with other plants.
• Reduce watering and stop fertilising during cooler Australian winter months when growth slows.

• Provide bright, indirect light away from direct sun which can scorch the delicate leaves. East-facing windows work perfectly.
• Keep soil consistently moist but not waterlogged, checking weekly during growing season. Reduce watering in winter months.
• Maintain high humidity levels above 50% using humidity trays or room humidifiers. Group with other tropical plants.
• Keep temperatures between 18-24°C and protect from cold drafts and air conditioning. Consistent warmth is essential.
• Feed monthly during spring and summer with diluted liquid fertiliser. Stop feeding in autumn and winter.

• Spider mites can appear in low humidity conditions, causing stippled leaves. Increase humidity and wipe leaves with damp cloth regularly.
• Brown leaf edges indicate low humidity or fluoride in tap water. Use filtered water and place on humidity tray.
• Root rot from overwatering causes yellowing leaves and musty soil smell. Reduce watering frequency and ensure proper drainage.
• Fungus gnats thrive in constantly moist soil. Allow soil surface to dry between waterings and use yellow sticky traps.
