Group plants for humidity 

If you want to improve the humidity levels in your home or office, grouping plants together is a great way to do it. The closer the plants are to one another, the more moisture they will be able to share. This will help to keep the air moist and comfortable. Some plants that are good for increasing humidity in space include ferns, ivy, and philodendrons. These plants can create a dense foliage canopy that will trap moisture in the air. You can also try adding moss or lichen to your grouping mix to help increase the moisture retention capacity of the plant material.
