The Ralta plant, botanically known as Tradescantia spathacea, is a popular ornamental plant. It is also called Moses-in-the-Cradle, Oyster Plant, and Boat Lily, names that allude to its unique appearance. Valued for its striking foliage and straightforward upkeep, Tradescantia spathacea is a favored choice for indoor cultivation and outdoor landscapes in suitable climates. It is an appealing option for many gardeners.
Understanding Moses-in-the-Cradle
The Moses-in-the-Cradle plant has distinctive physical characteristics. It forms a rosette of sword-shaped leaves, up to 12 inches long, with dark green upper surfaces and vibrant purple undersides, creating a striking contrast. Small white flowers emerge from unique boat-shaped, purple bracts nestled within the leaf axils. These bracts give rise to its common names like “Boat Lily” or “Moses-in-the-Cradle” due to their resemblance to a baby in a basket. This evergreen perennial is native to southern Mexico, Belize, and Guatemala, thriving in warm, humid conditions.
Moses-in-the-Cradle Care
Light
Moses-in-the-Cradle plants flourish in bright, indirect light, mimicking their natural habitat. Placing them near a north or east-facing window indoors provides ideal light without harsh direct exposure. They can tolerate some direct sunlight, particularly in the morning or late afternoon. However, intense midday sun can scorch their leaves. Insufficient light may cause the vibrant purple coloration on the leaf undersides to fade, resulting in a greener appearance.
Watering
Moses-in-the-Cradle prefers consistent moisture. Allow the top inch or two of the soil to dry out completely between waterings. Water thoroughly until water drains from the pot’s bottom, then discard any excess. Avoid overwatering to prevent root rot, which occurs if the soil remains waterlogged.
Soil and Fertilizing
A well-draining potting mix is suitable for Moses-in-the-Cradle, allowing for aeration while retaining some moisture. A blend of peat moss, perlite, and regular potting soil is recommended. During the active growing season in spring and summer, the plant benefits from regular fertilization. Apply a balanced, water-soluble fertilizer, such as a 10-10-10 or 20-20-20 NPK ratio, diluted to half strength, every 2-4 weeks. Reduce or cease fertilization during the cooler growth periods of fall and winter.
Temperature and Humidity
Moses-in-the-Cradle prefers warm conditions, with an ideal temperature range between 60°F and 85°F (15°C to 29°C). It is sensitive to cold temperatures; exposure below 50°F (10°C) can cause leaf damage and stunted growth. Average household humidity is acceptable for this plant. Higher humidity levels, around 50-70%, can be beneficial for its health and vibrant foliage, especially in drier indoor environments.
Propagating Moses-in-the-Cradle and Common Issues
Propagating Moses-in-the-Cradle is straightforward. It can be achieved through stem cuttings or by dividing offsets. Stem cuttings root readily in water or directly in moist potting soil. When propagating by division, mature plants can be gently separated into smaller sections, ensuring each has roots and foliage to establish independently.
Several common issues can affect Moses-in-the-Cradle. Leggy growth, characterized by elongated stems and sparse leaves, indicates insufficient light. Brown leaf tips are a sign of low humidity, which can be improved by increasing moisture around the plant. Overwatering can lead to root rot, causing leaves to yellow and wilt despite moist soil. Pests like spider mites and mealybugs can infest the plant, identifiable by fine webbing or white, cottony masses, and can be addressed with horticultural oil or by wiping affected areas.
