Care Guide
How to Water
Water when the top inch of soil feels dry, usually every 7 days. Use room-temperature water and avoid letting the plant sit in standing water. In drier environments, watering may be needed more frequently. Overwatering is the primary cause of problems in this species.
Lighting
Place in a spot with bright indirect light, away from windows with intense direct sun. It tolerates lower light conditions but flowers best with more luminosity. Avoid direct sunlight, which can scorch the leaves and fade their color.
Ideal Soil
Use rich, well-draining soil with a slightly acidic pH (5.8-6.5). A mix of potting soil, perlite, and pine bark works very well. Avoid heavily compacted soils or those with excessive moisture retention.
Recommended Pot
Ceramic or terracotta pots with good drainage are ideal, as they allow root respiration and prevent moisture buildup. Avoid pots without drainage holes.

Common Problems
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Phytophthora Root Rot
Disease caused by fungus-like organisms (oomycetes) that live in soil and can survive for years. It affects roots, stem, and crown of plants, being especially severe in waterlogged or poorly drained soils. It is the second most common cause of root rot in trees and shrubs.
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.
Meaning & Symbolism
Symbolizes peace, purity, and spiritual renewal. The white spathe is associated with innocence and calm. Widely used as a gift of sympathy and placed in spaces intended to convey serenity and hope.
