The Bird of Paradise (Strelitzia reginae) is a tropical plant native to South Africa, thriving in warm, humid climates. During winter, its growth slows due to reduced light and lower temperatures. Whether grown indoors or outdoors, the plant requires adjustments in care to survive the colder months. From the plant's perspective, winter is a period of dormancy, and proper care ensures it remains healthy until spring.
When kept indoors during winter, the Bird of Paradise faces challenges like dry air and limited sunlight. Here’s how to address its needs:
The plant relies on bright, indirect light for photosynthesis. In winter, daylight hours shorten, so place it near a south-facing window or supplement with grow lights. Without adequate light, the plant may become leggy or fail to produce new leaves.
During dormancy, the Bird of Paradise's water needs decrease. Overwatering can lead to root rot, so allow the top 2-3 inches of soil to dry out before watering. The plant signals thirst through slightly drooping leaves, but avoid letting the soil become bone dry.
Indoor heating reduces humidity, stressing the plant. Mist the leaves regularly or use a humidifier to maintain 40-60% humidity. Brown leaf edges indicate low humidity, a sign the plant is struggling to retain moisture.
The ideal winter temperature range is 55-65°F (13-18°C). Avoid placing the plant near drafts or heaters, as sudden temperature fluctuations can shock it. The plant prefers stability, mimicking its natural habitat.
In regions with mild winters (USDA zones 9-11), the Bird of Paradise can survive outdoors with extra protection. Here’s what the plant needs:
Frost damages the plant’s leaves and roots. Cover it with frost cloth or mulch the base to insulate the roots. If temperatures drop below 24°F (-4°C), consider moving potted plants indoors temporarily.
Outdoor plants also enter dormancy, so reduce watering frequency. Ensure the soil drains well to prevent waterlogging, which can suffocate roots in cold weather.
Winter winds can desiccate leaves. Shield the plant with a windbreak or burlap screen. The plant’s large leaves are prone to tearing, so minimizing wind exposure helps preserve its energy.
The Bird of Paradise’s metabolic activity slows in winter, so avoid fertilizing during this period. Excess nutrients can harm dormant roots. Instead, resume feeding in spring when growth resumes. Prune only dead or damaged leaves to redirect energy to healthy parts of the plant.
The plant may exhibit stress through yellowing leaves, stunted growth, or leaf drop. Address these issues by adjusting light, water, or humidity levels. For example, yellow leaves often indicate overwatering, while brown tips suggest low humidity. Observing these signals helps tailor care to the plant’s needs.
