Monstera plants, native to tropical rainforests, thrive in warm, humid environments. During winter, indoor conditions often become dry and cold, which can stress the plant. To mimic its natural habitat, adjust care routines to maintain humidity, warmth, and indirect light. Reduced daylight hours and lower temperatures slow the plant’s growth, so watering and feeding should be scaled back accordingly.
Overwatering is a common issue in winter. Monsteras enter a semi-dormant state, requiring less water. Allow the top 2–3 inches of soil to dry out between waterings to prevent root rot. Use room-temperature water to avoid shocking the roots. Ensure pots have drainage holes, and empty saucers promptly to avoid waterlogging. Signs of overwatering include yellowing leaves, while underwatering may cause drooping or crispy edges.
Indoor heating systems reduce humidity, which can lead to brown leaf tips. Increase humidity by:
Shorter days mean less natural light. Move your Monstera closer to a bright, east- or north-facing window to maximize indirect sunlight. Avoid direct winter sun, which can scorch leaves. Rotate the plant weekly to ensure even growth. If light is insufficient, supplement with a grow light for 6–8 hours daily to maintain healthy foliage.
Monsteras prefer temperatures between 65–85°F (18–29°C). Keep them away from cold drafts (windows, doors) and heat sources (radiators, vents), which can cause stress. Nighttime temperatures shouldn’t drop below 60°F (15°C). Sudden temperature fluctuations may lead to leaf drop or stunted growth.
Since growth slows in winter, pause fertilizing from late fall to early spring. Excess nutrients can build up in the soil, harming the roots. Resume a balanced liquid fertilizer (diluted to half strength) in spring when new growth appears. Organic options like compost tea can be used sparingly if the plant shows signs of nutrient deficiency.
Remove yellow or damaged leaves to redirect energy to healthy growth. Wipe dust off leaves with a damp cloth to improve photosynthesis. Trim leggy stems to maintain shape, but avoid heavy pruning until spring. Sterilize tools before use to prevent disease spread.
Dry indoor air attracts spider mites, mealybugs, and scale. Inspect leaves weekly, especially undersides. Treat infestations early with insecticidal soap or neem oil. Isolate affected plants to prevent spreading. Increasing humidity deters pests naturally.
Winter is not ideal for repotting due to slowed root activity. If necessary (e.g., root-bound or soil issues), use fresh, well-draining soil and a pot slightly larger than the current one. Minimize root disturbance and water sparingly afterward to reduce transplant shock.
