Do Money Trees Like Humidity? Here’s What They Need

The money tree, Pachira aquatica, is a popular houseplant known for its braided trunk and lush leaves. A frequent question is whether these plants need humid conditions to stay healthy. Understanding their environmental preferences is key to ensuring they remain a vibrant addition to your indoor space.

Ideal Humidity for Money Trees

Money trees are native to the tropical wetlands of Central and South America, so they are accustomed to a consistently moist and warm atmosphere. They perform best when the relative humidity is at 50% or higher. This moisture level helps the plant maintain its turgor pressure, keeping the leaves firm and preventing excessive water loss through transpiration. The average home, particularly in colder climates during winter, can have humidity levels well below 30%, often requiring intervention from the owner.

Signs of Incorrect Humidity Levels

Observing your plant’s leaves is the most effective way to diagnose issues with ambient moisture. When the air is too dry, the most common sign is the development of brown, crispy edges or tips on the foliage. The leaves may also begin to curl inwards as they attempt to conserve water. A combination of yellowing leaves, browning tips, and a generally brittle appearance also points toward insufficient humidity as a likely cause.

While less common for indoor settings, excessively high humidity without proper air circulation can also cause problems. If the air is too stagnant and damp, you might see the development of dark spots on the leaves, which can indicate a fungal infection. Mold or mildew appearing on the surface of the soil is another indicator that the environment is too moist and lacks adequate airflow, creating conditions where pathogens can flourish.

How to Increase Humidity

One of the most effective ways to provide consistent moisture is by using a humidifier, which allows you to set a specific humidity level and maintain it with minimal effort. A simple technique involves creating a pebble tray. Fill a shallow tray with a layer of pebbles, add water until it sits just below the top of the stones, and place the plant’s pot on top. As the water evaporates, it increases the humidity around the plant, ensuring the pot itself is not sitting in water, which could lead to root rot.

Grouping your money tree with other houseplants is another effective strategy, as their collective respiration creates a more humid localized environment. You can also place the plant in a naturally humid room, like a kitchen or a bathroom, provided it receives adequate indirect sunlight. While misting the leaves is a popular practice, it offers only a temporary boost and must be done frequently to have a lasting effect.
