Calathea Lancifolia 'Rattlesnake'

Getting Started with Your Calathea Lancifolia 'Rattlesnake'

1. Light: Your Rattlesnake Calathea is happiest in medium to bright, indirect light. Keep it out of direct sun, which can scorch the patterned leaves. It is well suited to bright but shaded bedrooms, living rooms, and offices.
2. Potting and Drainage: Use a well-draining potting mix that holds some moisture, in a pot with drainage holes. The soil should stay evenly moist but never soggy, so excess water must be able to escape.
3. Placement: It grows 18 to 30 inches tall and 12 to 18 inches wide, with long, upright leaves that make a bold centerpiece for shelves, plant stands, or a bright corner. Keep it between 65 and 80 degrees Fahrenheit, away from exterior doors and air conditioning vents.

Care Instructions

1. Watering: Water when the top inch of soil feels dry, keeping the soil evenly moist but not soggy. Always use filtered or distilled water, since minerals in tap water can cause leaf spots and brown edges on calatheas.
2. Humidity: This calathea loves high humidity. Mist regularly, use a pebble tray, or place it near a humidifier to keep the leaves lush. Placing it in or near a bright bathroom is another easy way to give it the moisture it craves.
3. Fertilizing: Feed with a balanced liquid houseplant fertilizer diluted to half strength about once a month in spring and summer. Skip feeding in fall and winter. Too much fertilizer can burn the roots and brown the leaf edges.
4. Pest Monitoring: Spider mites love dry air, so check the leaf undersides regularly for fine webbing or speckling. Wipe the leaves with a soft, damp cloth using filtered water, and treat any pests with insecticidal soap. Good humidity is the best prevention.

Maintenance and Long-Term Care

1. Repotting: Repot in spring every year or two, when roots fill the pot, moving up just one size with fresh, well-draining mix. Keep watering consistent afterward, as calatheas can sulk briefly after being moved.
2. Pruning and Cleaning Leaves: Trim brown, crispy edges with clean scissors for a neater look, and remove fully yellowed or damaged leaves at the base. Wipe dust from the leaves gently with a soft cloth and filtered water.
3. Propagation: Calatheas are propagated by division rather than cuttings. When repotting in spring, gently separate a clump with its own roots and several leaves, pot it in fresh mix, and keep it warm and humid while it settles in.

Additional Tips for Calathea Lancifolia 'Rattlesnake'

1. Pet Safety: Calathea 'Rattlesnake' is non-toxic to cats and dogs, making it a pet-friendly choice. Its striking leaves can still attract curious pets, and chewing any plant may cause mild stomach upset, so it is best displayed on a shelf or plant stand.
2. Curling Leaves: Leaves curl mainly because of thirst or low humidity. Check the soil and water if the top inch is dry, then raise humidity. Curling can also come from cold drafts or too much light, so keep it away from vents and harsh sun.
3. Brown Leaf Edges: Brown, crispy edges usually come from low humidity or minerals in tap water. Switch to filtered or distilled water and boost humidity with a humidifier or pebble tray. Trim damaged edges with clean scissors for a neater look.
4. Moving Leaves: The leaves follow the light and fold upward slightly at night, a trait called nyctinasty. This daily movement is why calatheas are often grouped with prayer plants, and it is normal and a sign of a healthy plant.
