How to grow Calathea Lancifolia seeds

Choose Your Planting Method

• Indoors: Start seeds indoors at any time of year; warm conditions give the most reliable results.
• Outdoors: Only suited to year-round outdoor growing in frost-free tropical climates (zones 10-11); elsewhere grow it as a houseplant.

Prepare Your Materials

• Small pots or seed trays with drainage holes
• Light, well-draining peat- or coco-coir-based potting mix
• Clear humidity dome or plastic wrap to hold moisture
• Spray bottle for gentle watering

Sowing the Seeds

• Soak seeds in warm water for 12-24 hours before sowing.
• Sow on the surface and cover with about 1/8 inch (2-3 mm) of mix; press gently.

Provide the Right Conditions

• Light: Bright, indirect light; keep direct sun off seedlings.
• Temperature: 70-80°F (21-27°C) for germination; plants grow best at 65-80°F (18-27°C).
• Humidity: High humidity is important - use a dome or pebble tray, and ventilate daily to prevent mold.

Germination

• Seeds typically sprout in 3-6 weeks, sometimes up to 8 weeks.
• Keep the mix evenly moist at all times, never soggy.

Transplanting

• Move seedlings to individual pots when they have several leaves and stand about 2 inches tall.
• Handle roots gently and water in after potting up.
• Keep warm and humid after transplanting; no hardening off is needed for indoor plants.

Care Tips

• Sun: Bright, indirect light year-round.
• Water: Keep soil consistently moist; do not let it dry out completely.
• Fertilizer: Feed monthly in spring and summer with a half-strength balanced liquid fertilizer.
• Extra: Keep away from cold drafts and dry heating vents.

Bloom Time:

Calathea rarely flowers when grown indoors, so grow it for its patterned foliage rather than blooms.
