The Tradescantia spathacea, commonly known as Moses in the Cradle, Boat Lily, or Oyster Plant, is a striking tropical plant. It features sword-shaped leaves that are deep green on top and vibrant purple underneath. This perennial also produces small white flowers nestled within boat-shaped bracts, which give the plant its common names. Moses in the Cradle is a popular choice for both indoor and outdoor settings due to its low maintenance and attractive foliage.
Caring for Your Moses in the Cradle Plant
Light Requirements
Moses in the Cradle plants thrive in bright, indirect light. Placing them near a north or east-facing window indoors provides suitable illumination, allowing leaves to maintain vibrant coloration without harsh direct sunlight. While the plant tolerates some direct morning or late afternoon sun, intense midday rays can scorch leaves and fade colors. Insufficient light can lead to less vibrant colors, indicating a need for relocation to a brighter spot.
Watering Needs
Moses in the Cradle prefers consistently moist soil, but allow the top inch or two to dry out before watering again. Overwatering can lead to root rot. During the active growing season (spring and summer), the plant requires more frequent watering. Reduce watering in fall and winter as growth slows. Ensure the pot has adequate drainage holes to prevent water accumulation.
Ideal Soil Mix
A well-draining potting mix is essential for Moses in the Cradle. A general houseplant mix works well, and incorporating perlite or sand enhances drainage and aeration. The soil should retain some moisture but not become waterlogged, allowing for proper root penetration.
Temperature and Humidity
Tradescantia spathacea prefers warm temperatures, ideally between 60°F and 85°F (16°C and 29°C). It is sensitive to cold, so avoid temperatures below 50°F (10°C) and keep the plant away from drafts or cold windows. Moses in the Cradle appreciates moderate to high humidity (50% to 70%). If your indoor environment is dry, especially in winter, increase humidity through misting, using a pebble tray, or placing a humidifier nearby.
Fertilizing Schedule
Moses in the Cradle benefits from regular fertilization during its active growing season (spring through summer). Apply a balanced, water-soluble houseplant fertilizer (e.g., 10-10-10 or 20-20-20 NPK) monthly, diluted to half strength to prevent over-fertilization. Reduce or stop fertilization entirely during fall and winter when growth slows.
Propagating Moses in the Cradle Plant
Moses in the Cradle can be propagated through division or stem cuttings.
Division
Division involves carefully separating sections of the plant, including their root systems, from the main clump. Remove the entire plant from its pot and gently pull apart the root ball into smaller sections, ensuring each new section has roots attached. Pot these newly divided plants individually in well-draining soil.
Stem Cuttings
Stem cuttings are another common propagation method. Select a healthy stem segment 4 to 6 inches long. Remove lower leaves to expose nodes where roots will form. Place the cutting in a jar of water with submerged nodes, or directly into moist, well-draining potting mix. Roots typically develop within a few weeks, allowing the new plant to be transplanted.
Addressing Common Problems
Yellowing leaves are a common issue, often caused by overwatering, which can lead to soggy soil and restricted root respiration. Ensure the soil dries out between waterings. Yellowing can also result from excess moisture on the leaves or a nutrient deficiency.
Browning leaves or crispy leaf tips often indicate underwatering or insufficient humidity. If the plant is not receiving enough water, its leaves may appear wilted. Low humidity, particularly in dry indoor environments, can also lead to brown leaf tips with yellow halos. Moving the plant away from heat sources and increasing ambient humidity can alleviate these symptoms.
Common pests include spider mites and mealybugs. Manage them by wiping leaves with soapy water or using insecticidal soap for infestations.
Is Moses in the Cradle Plant Toxic?
The Tradescantia spathacea is considered toxic if ingested by humans and pets. The plant’s sap contains substances that can cause irritation. If ingested, symptoms in pets and humans can include irritation of the mouth and throat, vomiting, and nausea. Contact with the sap on skin can also lead to irritation. Handle the plant with gloves, especially during pruning or repotting, and keep it out of reach of children and household pets.
