Group Your Indoor Plants Together

Bring your indoor plants together in one cozy cluster to create a mini-green oasis that they’ll absolutely love! Indoor plant grouping offers numerous benefits for plant humidity needs.

When you group your plants, they naturally release moisture into the air through transpiration, increasing the overall humidity in their vicinity. This is especially effective when combined with humidity trays or saucers filled with water placed underneath the plant pots.

The collective presence of plants creates a microenvironment that mimics a miniature rainforest, ensuring that your botanical companions thrive in optimal conditions. So, consider rearranging your indoor jungle for both increased plant humidity and aesthetic appeal.

Your plants will thank you!

Saucers With Rocks, Pebbles, or Glass Chips Filled With Water

Enhance your indoor oasis by incorporating saucers filled with rocks, pebbles, or glass chips into your plant care routine.

  • Rocks in saucers create a stable base for your pots.
  • Glass chips add an elegant touch to your plant display.
  • Pebbles prevent water from reaching pot drainage holes.
  • Water evaporation from these saucers increases humidity.
  • It is a practical and visually pleasing solution for your plants’ well-being.

Bowls Filled With Water

To create a lush, moisture-rich environment for your indoor plants, try placing bowls filled with water strategically near your green companions.

  • Enhancing humidity
  • Cost-effective
  • Low-maintenance
  • Increased comfort

Plant-Friendly Bowls:

  • Suitable for plants
  • Easy to maintain
  • Versatile placement
  • Ideal for kitchens

Strategically positioning these water-filled bowls in areas like the kitchen or bathroom can elevate humidity levels, benefiting your plants’ health. Remember to occasionally spray the water to maintain humidity effectively. If you’re feeling creative, consider growing some plants under glass for added moisture retention.


Misting your indoor green companions daily can help maintain their well-being, preventing dust buildup and supplying much-needed moisture.

  1. Mist Frequency: Aim for daily misting during dry periods or when your home’s humidity is low.
  2. Misting Techniques: Use a fine mist spray bottle to evenly coat leaves, avoiding excessive saturation.
  3. Mist Water Source: Opt for bottled spring or distilled water to prevent mineral buildup on leaves.
  4. Mist vs. Humidity Trays: While misting provides direct hydration, humidity trays offer a more sustained moisture source.

Keep your indoor ferns and prayer plants thriving by targeting misting, especially in hot spots, to prevent brown leaves and ensure their well-being.

Low Humidity Houseplants

Low Humidity Houseplants
Opt for indoor plants that thrive in arid conditions, such as succulents and cacti, when facing low indoor humidity levels. These resilient plants have a high humidity tolerance and can withstand dry air, making them perfect choices for homes with low humidity.

When dealing with the challenges of winter heating that can significantly reduce indoor humidity, these low humidity houseplants remain robust. However, it’s essential to be cautious with more delicate, thin-leaved plants like maidenhair ferns, palms, and prayer plants.

They are more vulnerable to the effects of low humidity and may require additional care in steamy settings.

To create a protective microenvironment for these plants, consider placing them in glass terrariums. These enclosed spaces help maintain higher humidity levels and shield your plants from issues like red spider mite infestations.

Incorporating humidity-loving plants in glass terrariums can be a game-changer, offering both aesthetic appeal and practical benefits in your quest to combat low indoor humidity.

Transitioning from the realm of low humidity houseplants, let’s delve into the crucial realm of maintaining your indoor garden’s health by avoiding hot spots and draughts.

  1. Humidity Solutions: In addition to careful plant placement, invest in humidity solutions such as the previously mentioned humidity trays or terrariums. These not only protect your plants from hot spots but also create microenvironments where humidity is regulated, ensuring your green companions flourish.
  2. Draught Avoidance: Draughts can quickly dry out your plants. Take measures to seal any gaps around windows and doors, preventing cold draughts from infiltrating your indoor oasis. This proactive step keeps your indoor climate stable, safeguarding your houseplants from unnecessary stress.

By implementing these strategies, you can avoid hot spots and draughts, creating an environment where humidity thrives, and your houseplants thrive in turn.

Spray With Water

To boost moisture levels around your indoor greenery, consider lightly spraying them with water using a fine mist spray bottle. Water misting is a simple yet effective method to maintain the essential moisture balance for your houseplants.

When engaging in indoor gardening, it’s crucial to pay attention to the specific needs of your plants. Some plants, like those with fuzzy leaves or originating from desert environments, require a bit more attention when it comes to hydration.

Regularly misting these plants can create a microenvironment that replicates their native conditions.

This practice not only aids in increasing household humidity but also helps in preventing issues like dry leaf tips and edges, which can occur when the air is too arid. By incorporating water misting into your plant care routine, you’ll be on your way to mastering the art of maintaining healthy, thriving houseplants.

Stand Plants on Gravel

Stand Plants on Gravel
Place a layer of gravel in a shallow tray, positioning your plants on top for an effective method to boost moisture around your indoor greenery. This simple yet highly efficient technique serves multiple purposes in your quest to increase humidity for houseplants.

The gravel benefits your plants in two significant ways. First, it creates a barrier that prevents your plants’ pots from sitting directly in any excess water that might accumulate in the tray. This elevation ensures that your plants’ roots won’t suffer from waterlogged soil, helping to maintain their health.

Second, the gravel increases the surface area for evaporation, leading to a gradual rise in humidity levels around your precious green inhabitants.

By setting up a gravel tray, you not only contribute to the overall indoor plant health but also create a more controlled environment for your houseplants. The humidity tray benefits are evident in how it mitigates the harsh effects of dry indoor air, especially during the winter months.

It helps you master the art of maintaining optimal humidity, providing your plants with the safe haven they need to thrive.

So, go ahead, stand your plants on gravel, and watch them flourish in the nurturing embrace of increased humidity.

Use the Bathroom

Use the Bathroom
Incorporate your bathroom into your plant care routine to take advantage of its natural moisture. Your bathroom can be a hidden gem for indoor gardening, offering a humid environment that many plants adore.

  • Bathroom Humidity: Bathrooms naturally have higher humidity levels due to showers and sinks, making them an ideal spot for humidity-loving plants.

  • Bathroom Plant Selection: Choose plants that thrive in high humidity, like ferns, spider plants, or peace lilies, and place them strategically in your bathroom.

  • Shower Benefits: During your daily shower, allow the warm water to create a mini-humid microenvironment. Group plants together near the shower for a refreshing moisture boost.

  • Gravel Tray Magic: Set up gravel trays under your bathroom plants to maintain humidity levels even when you’re not showering.

With these bathroom plant care tips, you can create a lush, tropical oasis right in your own home, ensuring your houseplants flourish in the perfect humidity they crave.

Grow Under Glass

Grow Under Glass
Transform your indoor oasis into a lush, otherworldly paradise by encasing your green companions within glass terrariums. This will turn your home into a humidity haven. Glass terrariums are not just decorative; they offer a range of benefits for both your houseplants and your aesthetic sensibilities.

These DIY wonders allow you to exercise control over the microclimate, ensuring that your plants thrive in the ideal humidity range. When selecting plants for your terrarium, opt for moisture-loving varieties such as ferns, mosses, and tropicals.

Leave cacti and succulents, which prefer dry air, outside. If you have a grow-light garden, consider using plastic curtains to create temporary humidity tents for your terrarium plants.

To maintain these miniature ecosystems, keep them near indirect sunlight. This will ensure they receive just the right amount of light and humidity. Water sparingly, as terrariums recycle moisture, and overwatering can lead to mold and root rot.

With careful attention, glass terrariums can transform your home into a captivating and thriving botanical paradise.


You have the tools to provide your houseplants with the humidity they need to thrive. Whether you opt for a humidity tray with rocks, a humidifier or diffuser, or the simple task of misting, the key to success is finding a balance that works for you and your plants.

Low humidity houseplants can be kept in the bathroom or under glass to ensure they get the moisture they need.

With a little bit of knowledge and the right tools, you’ll soon have the lush, thriving houseplant collection of your dreams.
