Dry air can cause leaf damage on many plants. Some simply can't take it at all, while others might be acclimated to it over a period of time.
The humidity in most homes is much lower than what you'd find in a plant's natural habitat. Most homes have rather low humidity levels compared to what most plants do the very best in. Most plants are adaptable to a range of humidity levels but some remain sensitive and will require extra care to ensure their leaves don't dry out.
SIGNS THAT THE AIR IS TOO DRY FOR YOUR PLANT
Dry, browning leaf tips and edges despite avoiding under and overwatering
Curled leaves
Newly developed leaves don't unfurl or have damage once unfurled
WHAT TO DO NOW
There are a few different ways to raise the humidity for your plants:
Invest in a humidifier and place it close to your plant. This is a quick and effective solution to increase the humidity levels of your home. Be careful of placing humidifiers in enclosed spaces such as greenhouses as it may contribute to damp, wet conditions.
Place the pot on a tray of pebbles filled with water. Just make sure that the plant's soil isn't in contact with the water to avoid root rot.
Group plants with similar lighting and humidity needs together. Because each plant gives off moisture through the process of transpiration, this will mean that the air surrounding a grouping of plants will be slightly more humid. Group plants with similar lighting and humidity needs together.
Mist more often. Misting doesn't actually have much of an effect on the humidity in the air but can reduce water loss and cool down plants' leaves when conditions are warm and dry. Remember that plants want to live in an evironment as close to their natural home as possible. Misting can help create a more natural environment and also keep plants leaves clean from dust and debris.
For plants that like a very high humidity level, you could even consider using a terrarium, glass box or plant cabinet.
QUESTIONS
HOW CAN I PREVENT THIS IN THE FUTURE? To assess how you can create a better environment for your plants, it's important to first understand contributing factors in your home. For example, do you use air conditioning in the warmer months? This will make the air significantly drier. Do you have good air circulation in your home? If not, a small fan nearby your plants will help improve air flow. Do you have constantly or even just seasonally dry air? If you're feeling it, your plants are likely feeling it as well. ItSimply put, the easiest solution to a dry air problem is to invest in a humidifier.
WHAT ARE THE BENEFITS OF INCREASING THE HUMIDITY LEVELS? Increased humidity can help your plants in many ways. Not only does it help your plant to drink and transpire water in a healthy way, it can also help unfurling leaves emerge without issues. Humidity levels within the plants preferred range means better and faster growth.
