Is Humidity Good for Orchids?

Orchids are among the most popular the tropical flowers that everyone can cultivate. Although they are gorgeous, they can be difficult to keep happy.

This snarky tropical plant is a fan of attention, and prefers to be left to its own devices as well. I’ve had a huge learning curve in understanding what’s the best to do with this particular plant.

Orchids thrive in humidity and flourish in conditions of humidity that are just right. It isn’t ideal to have too high levels of humidity, but you need some. It was a challenge making sure my orchids were humid enough that they were happy, but not enough to cause the orchids to drop.

The care and maintenance of orchids requires an envious thumb. The most important aspect of treatment of orchids is knowing the impact of humidity on this flower.

It is also important to understand the amount of humidity your orchids require and how to determine that. If your orchid is dry, it’s important to know how to boost the humidity of your orchid in order to keep it healthy.

How Much Humidity Do Orchids Need?

We’ve touched on this before in the previous post however, most orchids require between 40 and 70 percent humidity in air. If you reside in an area that is naturally humid it is unlikely that you need to get to the upper end of this range. If you’re in an area that’s dry and is subject to forced heat, you’ll must reach 70 percent humidity.

Forced heat can deprive the house of its humidity which will not keep your orchid content. So, you’re going to require introducing an environment that is humid enough to make your orchid feel at ease.

How Does Humidity Affect Orchids

Orchids flourish when humidity is between 40% and 70%. The higher amount is particularly important when you reside in an area that has an energy source that is forced. The humidity helps the orchid to flourish by giving them an ongoing source of water.

If the humidity is too low, plants are prone to die because they require the water to keep their appearance. The slim stem, in conjunction with the bigger flowers require an irrigation source to keep the plant in a straight position and lively. The humid air ensures a continuous flow to the plant, allowing it absorb the amount it requires to stay healthy.

But, you must ensure that you have a source of air in addition.

Air Source and Humidity

In addition to their humidity levels, orchids require air circulation to keep their vibrancy. The humid air can weigh the orchid down if it’s not placed in an area that circulates air. A small fan to ensure that humid air circulates gently will help keep the plant healthy.

I would recommend placing the orchid inside a space with a fan paddle which can be adjusted to a slow moderate or slow speed. It is not advisable to place the plant close to an oscillating fan, but instead in a place that will be able to feel the impact. One of the errors I made was to forget that plants require this airflow even at night.

What can the correct air circulation do to help the plant flourish in humid conditions? It helps create an easy natural movement of the leaves that makes it feel like you’re in the outdoors.

It also allows just the proper amount of air moisture to be absorbed by the leaves without weighting them down by a lot of water. The gentle flow of moist air is your orchid’s dream.

Benefits of Air Circulation Include:

  • Reduces the risk of bacterial infections and other mold spores that can grow on your orchids.
  • It assists in keeping the temperature at a moderate level on hotter than normal days, which encourages the growth of new plants.
  • A proper airflow will ensure that your orchids get sufficient carbon dioxide and oxygen they require to ensure proper photosynthesis. (That is what that your orchids go through to convert the sun’s energy into electricity.)
  • The exchange of air helps to eliminate air pollutions. Ethylene is one of the pollutants that could cause buds to dry out and fall.

How do you measure humidity in your home?

Humidity is measured primarily as relative humidity. Relative humidity can tell you the amount of humidity in the air, by showing how much moisture is present in relation to the volume of air at a certain temperature.

To help you it is measured using the amount of water vapor that the air holds at a certain temperature. When humidity is 100 you’ll see condensation.

In general warm air is more able to hold moisture than colder air.

To determine the humidity of your home, to keep your orchid healthy You need to purchase an instrument called a hygrometer.

There are two main kinds of hygrometers you can pick from: either a mechanical or one that is electric. Both will function well provided that it is properly calibrated. They are available in any hardware retailer.

The Different Types of Hygrometer

The kind of hygrometer you choose to use will depend on what you prefer to use it for. Personally, I find it more convenient to use an electric one since it’s quick and easy to give an indication.

Helping your orchids deal with high humidity

Although your orchid may be enjoying the humidity however, you must be cautious in areas of high humidity. If the air quality at your house are above 70%, then you must help your orchid to continue to flourish. There are some ways you can aid your orchid in coping the increased humidity.

Avoid Excessive Watering

It is not advisable to keep your orchid watered constantly in normal conditions, and even more so when it’s extremely humid in your house.

Your orchid draws water from the air whenever it is in need and, with the right airflow, it will not draw things it doesn’t require. So, if you add additional water for your orchid during high humidity, you’ll effectively drown it.

Improve Air Circulation

I mentioned this earlier in my post. It is important to ensure that there is adequate air circulation in the area where you keep your orchids. This is essential in ensuring that your orchids don’t become overwhelmed by too much water.

A fan that circulates gently that moves the air naturally away from your orchid could aid in coping with the extreme humidity levels within the home by removing any excess moisture.

Orchid Placement

Like you have a favourite spot within your house, the orchid has a favorite spot too. A proper orchid arrangement will allow your orchid cope with the humidity better. It is recommended to put your orchids close to east or south-facing windows. These are the ideal spots for this stunning plant.

West windows are often too hot, as they absorb afternoon sun, and north windows are too dark for this tropically thriving plant.

Sometimes, you’ll need to move your plant around as the seasons change in order to ensure that they’re getting the highest temperatures.

If, for instance, you reside in the North region, you’ll want to put your plant in an east-facing window during winter months, when sunlight is far and between.

Use the Suitable Soil

The correct soil can help in extreme humidity by stopping your orchid from taking in too much water. There are many pots you can choose to ensure that your orchid flourish. The most well-known one is an orchid-potting soil which includes a variety of other types of.

The ideal mediums for orchids can be peat moss and tree fern. They will aid in keeping the proper levels of moisture for your flower to keep their beautiful appearance. There are other mixes that contain additional ingredients like charcoal, rock wool, cork, sand, as well as polystyrene foam.

A potting soil that is suitable and has the correct mix of ingredients will prevent your orchid from getting waterlogged. Try experimenting with different types of soils to determine which is most effectively for the orchid you have.


In addition to the other essential elements to ensure that your orchid can withstand the high humidity, you require the right lighting. It may not appear to be the best choice for humid conditions however it could be. The proper lighting will assist to evaporate water that is not needed.

Your orchids will require certain qualities of lighting, which you may not know about. A quick overview of my experience is to choose lighting that is colored in the spectrum. These colors can help your orchid understand the various cycles of growth and blooming.

The fluorescent bulbs are perfect for the growth of orchids since they disperse the light evenly, unlike other kinds of light sources do. Additionally they tend to last longer and retain their brightness with time. Utilizing these kinds of bulbs is a cost-effective method to ensure that your orchid gets the proper amount of light required for optimal growth.

Signs Your Orchid Needs More Humidity

There are some important things to watch out for when you are looking after your orchid. It is important to be on the lookout to make sure that your orchids receive sufficient humidity.

The most effective method to determine whether your orchid requires humidity is to test the soil. When the soil appears dry, and it crumbles upon your fingers the orchid is in need of more water.

Another thing to watch out for is if the leaves are beginning to turn get brown around the edges. The edges that are brown are another indication that your orchid isn’t drinking enough water.

Flowers falling from the sky and even flowers that begin to fall are obvious signs that your orchids will require some moisture and speedy.

If the rest of your home is warm and dry air, it’s likely that your orchids feel it too. If you notice how dry it is in your home, your orchids are equally conscious. What you have to do is make sure to create a humid environment in the earliest time possible.

Ways to Increase Humidity for Your Orchids

If you feel the humidity in your room dwindling There are ways that to increase the humidity in order to keep your plants happy.


One of the easiest and most efficient ways to boost humidity is to use the use of a humidifier. By strategically placing a humidifier within your room you will be able to rapidly increase the humidity to optimum levels. Be careful not to put the humidifier close to the orchids or else you could over-water them.

Make sure you keep your humidifier in good condition so that you can prevent the growth of fungal organisms. Follow the manufacturer’s guidelines regarding how and when to wash your humidifier.

Humidity Plate

Another method to increase the humidity of your orchids is to create an the perfect environment for humidity to grow. A dish with pebbles and filled with water to just less than what the pebbles in water will naturally increase humidity. The water evaporates into the air and produce the humidity your flower needs.


Gather some orchids. It is not a good idea to keep them to be so close that they crowd one another. The orchids being close together will allow them to create their own micro-humidity ecosystem. The orchids will naturally create an environment that spreads the moisture from plant to flower efficiently.


It’s the most basic method of increasing the humidity within your plants. Misting is a method that allows you to water your plant but without actually pouring water over the plants. Find a spray bottle that mists, and fill it up with water that is lukewarm. It is important not to allow the water either to get too cool or too warm.

Mist your flowers gently by sprays that do not direct towards the plants. The mist should be deposited on the plant like an occasional light drizzle. If you do this several times per week, you can increase the humidity to levels that are optimal for your plants.

Be cautious not to mist the plants. A lot of mist isn’t appropriate for them. So, ensure that you’re giving your plants sufficient water so that they remain well and hydrated, but not depleted.

Final Words

Maintaining your orchids’ health isn’t an easy job. It requires a lot of trial and trial and beauty in good health. I’ve learned how to avoid making mistakes when it is time to take good care of orchids. Sharing this knowledge with you can help you avoid a few mistakes that can be harmful to your orchid.

Be sure to examine the humidity levels of the area where you keep your orchids. If you notice that the room is too humid or too humid follow the steps above to ensure you get the ideal humidity for orchids.

If you follow these steps by following these steps, you will increase the chances of growing healthy and happy orchids.
