Clivia plants, native to subtropical regions of South Africa, naturally enter a dormancy period during colder months. This dormancy is crucial for their growth cycle, as it allows them to conserve energy for spring blooming. During winter, Clivia's metabolic processes slow down, reducing water and nutrient uptake. Mimicking these natural conditions indoors is key to maintaining plant health.
Clivia thrives in temperatures between 50–60°F (10–15°C) during winter. Exposure to temperatures below 40°F (4°C) can cause leaf damage or root rot. Avoid placing the plant near cold drafts, windows, or unheated spaces. A consistent, cool environment mimics their native habitat and prepares them for flowering in spring.
During dormancy, Clivia requires significantly less water. Overwatering is a common cause of root rot in winter. Water only when the top 1–2 inches of soil feel dry, typically every 3–4 weeks. Reduce watering frequency further if the plant is kept in cooler conditions. Ensure proper drainage to prevent waterlogged soil.
While Clivia prefers bright, indirect light year-round, winter sunlight is less intense. Place the plant near a south- or east-facing window to maximize light exposure. Avoid direct sunlight, which can scorch leaves. If natural light is insufficient, supplement with grow lights for 6–8 hours daily to maintain foliage health.
Clivia does not require fertilization during winter dormancy. Resume feeding only in early spring with a balanced, diluted fertilizer (e.g., 10-10-10). Fertilizing in winter can disrupt the plant's rest period and lead to weak growth or nutrient burn.
Indoor heating in winter can reduce humidity, stressing Clivia. Maintain humidity levels of 40–50% by using a humidifier or placing the pot on a pebble tray with water. Ensure good air circulation to prevent fungal diseases, but avoid direct drafts from heaters or vents.
Clivia is susceptible to pests like mealybugs and spider mites in dry winter conditions. Inspect leaves regularly and wipe them with a damp cloth to remove dust and pests. Treat infestations with insecticidal soap or neem oil, ensuring thorough coverage.
As winter ends, gradually increase watering and reintroduce fertilizer to signal the end of dormancy. Move the plant to a slightly warmer location if it was kept in cooler temperatures. This gradual transition encourages healthy new growth and flower bud formation.
