Haworthiopsis, a genus of small succulent plants, originates from arid regions of Southern Africa. In winter, these plants enter a semi-dormant state, reducing their growth rate to conserve energy. During this period, their care requirements shift significantly compared to warmer months. From the plant's perspective, winter survival hinges on mimicking their natural habitat—minimal water, cooler temperatures, and reduced light intensity.
In winter, Haworthiopsis requires far less water due to slowed metabolic activity. Overwatering can lead to root rot, a common cause of death for succulents in cold months. Water only when the soil is completely dry, typically every 4–6 weeks. Use the "soak and dry" method: thoroughly water the soil, then allow it to dry out entirely before the next watering. The plant's thick, fleshy leaves store moisture, enabling it to withstand prolonged dry periods.
Haworthiopsis prefers cooler temperatures in winter, ideally between 50–60°F (10–15°C). Avoid exposing the plant to freezing temperatures, as frost can damage its cells. Indoors, keep it away from heaters or drafts, which can cause sudden temperature fluctuations. Low humidity is preferable, as high humidity combined with cold can promote fungal infections. The plant's natural adaptation to dry climates makes it resilient in arid indoor conditions.
While Haworthiopsis thrives in bright, indirect light year-round, winter sunlight is less intense. Place the plant near a south- or east-facing window to maximize light exposure. If natural light is insufficient, supplement with a grow light for 6–8 hours daily. The plant's rosette shape helps it capture light efficiently, but prolonged low light can cause etiolation (stretching), weakening its structure.
Fertilizing Haworthiopsis in winter is unnecessary and potentially harmful. The plant's dormant state means it cannot utilize nutrients effectively, leading to salt buildup in the soil. Resume fertilization in spring when active growth resumes. The plant's slow growth habit ensures it can thrive without frequent feeding, relying on stored nutrients in its leaves.
Winter stress can make Haworthiopsis more susceptible to pests like mealybugs and spider mites. Inspect the plant regularly, especially under leaves and near the soil line. Isolate infected plants to prevent spread. The plant's compact growth and waxy leaf coating offer some natural pest resistance, but poor air circulation or overwatering can compromise this defense.
Winter is not the ideal time to repot Haworthiopsis, as the plant's roots are less active and more prone to damage. If repotting is necessary, use a well-draining soil mix (e.g., cactus/succulent blend) and handle roots gently. The plant's shallow root system is adapted to rocky soils, so excessive disturbance can disrupt its delicate balance.
Watch for discoloration, shriveling, or leaf drop, which indicate stress. Yellowing leaves may signal overwatering, while brown tips suggest sunburn or dehydration. The plant's ability to reabsorb lower leaves is a natural survival tactic, but excessive leaf loss warrants care adjustments. Its resilience allows recovery with proper intervention.
