Monstera deliciosa, commonly known as the Swiss cheese plant, originates from tropical rainforests in Central and South America. In its natural environment, it thrives under the canopy of taller trees, where it receives bright, indirect sunlight and high humidity. The plant is adapted to warm temperatures, typically between 65°F and 85°F (18°C–29°C), and is sensitive to frost or extreme heat. When considering whether to place your Monstera outside in summer, it’s essential to mimic these conditions as closely as possible.
Moving your Monstera outside during the summer months can offer several advantages. First, increased natural light can promote more vigorous growth and larger, more fenestrated leaves. Second, outdoor humidity levels are often higher than indoors, which benefits the plant’s tropical nature. Third, exposure to gentle breezes can strengthen the plant’s stems and reduce the risk of pests like spider mites, which thrive in stagnant indoor air.
While there are benefits, there are also risks to consider. Direct sunlight can scorch Monstera’s leaves, causing yellow or brown patches. Sudden temperature drops at night or heavy rain can stress the plant. Additionally, outdoor pests like aphids or mealybugs may infest the plant. Wind can also damage large leaves, leading to tearing or dehydration. To mitigate these risks, careful placement and monitoring are crucial.
To ensure your Monstera thrives outdoors, follow these guidelines:
Abruptly moving your Monstera from indoors to outdoors can shock the plant. To acclimate it, start by placing it outside for a few hours each day in a shaded area, gradually increasing the time over 1–2 weeks. This process, known as hardening off, helps the plant adjust to sunlight, temperature fluctuations, and wind.
Regularly inspect your Monstera for signs of stress, such as wilting, leaf burn, or pest infestations. Rotate the pot occasionally to ensure even growth. If heavy rain is forecasted, move the plant to a sheltered location to prevent waterlogged soil, which can lead to root rot. Fertilize monthly with a balanced, water-soluble fertilizer to support growth during the active summer season.
As summer ends and temperatures begin to drop, prepare to bring your Monstera back inside. Do this before nighttime temperatures consistently fall below 50°F (10°C). Check the plant thoroughly for pests and treat if necessary before reintroducing it to your indoor environment. Gradually reduce its outdoor time to help it readjust to lower light levels indoors.
