Thriving in the Tropics (at Home): Why Humidity Matters for Your Indoor Tropical Plants

Bringing the lush beauty of tropical plants indoors has become a growing trend for plant lovers and interior design enthusiasts alike. From the bold Monstera Deliciosa to the delicate Calathea and vibrant Orchids, these plants not only add visual appeal but also improve air quality and foster a calming environment. To keep them healthy and vibrant, one key element is often overlooked— humidity.

Why Humidity Matters for Tropical Plants

Tropical plants are native to rainforests and warm, moist environments where humidity levels typically hover between 60% and 90%. When we bring these plants into our homes, especially in regions with dry climates or during winter when indoor heating is running, we create an environment that’s far drier than they’re accustomed to. Most homes average 30% to 50% humidity—significantly lower than what tropical plants need.

When humidity is too low, tropical plants struggle to maintain their moisture balance. You may start to notice:

• Crispy, brown leaf edges
• Drooping or wilting leaves
• Slow or stunted growth
• Leaf curling or yellowing
• Increased susceptibility to pests

These are clear signs that your plant is stressed—and that the air around it is too dry.

How to Increase Humidity for Indoor Plants

Thankfully, there are several effective ways to boost humidity for your leafy friends:

1. Humidifiers

Investing in a cool mist humidifier is one of the easiest and most effective ways to increase humidity in a room. Place it near your tropical plants and run it for several hours a day. The best way to know how long your humidifier needs to run, is to purchase a hygrometer. This device measures the ambient humidity in the room.

2. Pebble Trays

The good ole controversial, pebble tray method. Set your plant pot on a tray filled with pebbles and water. As the water evaporates, it creates a microclimate of increased humidity around the plant. Just make sure the pot is not sitting directly in water to avoid root rot. Keep in mind that this method only provides humidity for the plant directly on the pebble tray. 

3. Group Plants Together

Plants release moisture through a process called transpiration. Grouping them together helps create a humid microenvironment, benefiting all the plants in the cluster.

4. Misting (With Caution)

While misting can provide temporary relief, it’s not effective in the long run and may encourage fungal issues if overdone. It’s best to use other methods to provide humidity to your plant baby.

5. Humid Planty Placements

Bathrooms and kitchens often have higher humidity due to regular water use. If there's enough natural light, these can be ideal spots for tropical plants like ferns, peace lilies, or philodendrons. If you don't have natural light, you can always supplement with plant lights from places like Amazon or Sansi.

Choosing the Right Tropical Plants

Some tropical plants are more humidity-tolerant than others. If you're just starting out or can’t raise humidity much, consider these relatively forgiving options:

• ZZ Plant (Zamioculcas zamiifolia)
• Snake Plant (Sansevieria)
• Pothos (Epipremnum aureum)
• Spider Plant (Chlorophytum comosum)

If you're ready to go all-in on a high-humidity setup, try:

• Calatheas
• Alocasias
• Ferns (like Boston or Maidenhair)
• Anthuriums
• Orchids

Final Thoughts

Caring for tropical plants indoors is about more than just light and water— humidity plays a crucial and vital role in their well-being. By mimicking their natural environment as closely as possible, you'll not only have healthier, happier plants but also a more vibrant and tropical feel in your living space.
