Pilea peperomioides Temperature and Humidity Tolerances Indoors

Pilea peperomioides plants (aka Chinese Money Plants) can handle temperatures ranging from 60 to 85ºF (15 to 30ºC) and can tolerate temperatures as low as 50 to 55ºF (10 to 13ºC). In my experience, indoor temperatures lower than these levels will cause problems. These plants also need humidity levels between 50 and 75%. I find that small plant humidifiers can help to provide sufficient supplemental moisture for those living in arid climates. Make sure you’re providing your Pilea with the warm and cozy conditions it needs to thrive with this helpful guide.

Pilea peperomioides Temperature and Humidity Tolerances

Native Temperature & Humidity Ranges Pilea peperomioides Receive

Pilea peperomioides plants are originally endemic to Southwestern China. These plants are mainly found in the southwestern areas of Sichuan Province and the western regions of Yunnan Province. In their native range, they grow at altitudes ranging from 1500 to 3000 meters.

Chinese money plants grow in dry, shady, temperate conditions in their native habitat. These plants seem hardy enough to survive temperatures of 32ºF (0ºC) in the wild. Sadly, wild Pilea peperomioides plants are considered to be endangered.

Because the symbolic Chinese money plant grows in temperate areas, it is well-suited to being kept as a houseplant. I find that average household temperatures will be sufficient. Although Pilea peperomioides plants survive in dry climates, high humidity levels are beneficial when growing indoors.

Signs Your Plant is Exposed to the Wrong Temperature & Humidity Levels

If your Pilea peperomioides plant isn’t getting the proper temperature or humidity levels, it could start having problems. Here are the main issues to look out for and how to fix them:

Brown spots on foliage

It may be too cold if you see brown spots or lesions on the leaves of your Pilea plant. In my experience, this problem occurs more in the winter if the plant is placed near a drafty window or air vent. The cold, dry air can shock the plant, resulting in brown marks. I move my plants away from drafty areas to provide more consistent temperatures when needed.

Curling leaves

If your Chinese money plant’s round, green leaves have started curling or evening dropping off entirely, the plant could be exposed to the wrong temperatures. In my experience, these plants may curl their leaves in response to sudden temperature changes or drafts.

Look at where your Chinese money plant is located. If it’s near a drafty window, air vent, or radiator, move it away from the source of the draft. These plants require consistent temperatures, and drafts can cause the temperature to fluctuate.

Depressions on the foliage

If the foliage of your plant has noticeable depressions in the middle, temperatures could be too high. Temperatures that are too hot or too cold can stress Chinese money plants.

Avoid temperatures above 85ºF (30ºC) and move the plant away from too hot areas. Excessively high temperatures can occur if your plant gets bright, direct sunlight on a south-facing windowsill. Transfer the plant to an east or north-facing windowsill to remedy this.

Ideal Temperature and Humidity Ranges

The best temperature range for Pilea peperomioides plants indoors ranges from 60 to 85ºF (15 to 30ºC). Depending on your climate, these temperatures are usually found in the average home. Chinese money plants require temperatures no lower than 50 to 55ºF (10 to 13ºC).

If the temperature is cooler than this, the plant will start suffering from problems like curling leaves. Protect your plant from temperature fluctuations as much as possible. Hot or cold drafts from air vents, open windows, and radiators often cause temperature fluctuations.

I find that these plants grow best with higher humidity levels ranging from 50 to 75%. This helps encourage new growth and a healthy environment for the plant. One of the best ways to provide the required humidity is to place them in a humid bathroom.

Placing your Pilea on a south-facing windowsill could expose it to excessively high temperatures in the summer. The best location for your plant will be an east-facing window. This will provide bright, indirect morning light while protecting the plant from the intense direct afternoon sun and high temperatures.

How to Boost Humidity in Your Home

If your average household humidity is below the required levels for Chinese money plants, don’t panic. There are several ways to increase the humidity around your plant.

I find that misting the foliage of my Pilea plant regularly can provide a slight humidity boost. However, it’s not a perfect solution because the water evaporates pretty quickly. If you do choose to mist, use a spray bottle to mist the foliage every few days.

A more efficient way to boost humidity is to use a humidifier (via Amazon). These devices are relatively cheap and can provide extra moisture to several plants at once. Group plants with similar humidity requirements close together near a humidifier to get maximum coverage.

This helps create a microclimate around the plants. When water evaporates from the leaves, all of the plants in the group will be able to use the moisture. Place your Pilea peperomioides plant next to other humidity-loving houseplants like calatheas, monsteras, or fiddle leaf figs.

Pebble trays (via Amazon) are another way of increasing the humidity. As the water evaporates, it’ll help improve the humidity. However, like misting, pebble trays aren’t as effective at boosting humidity as humidifiers.

I find that certain areas of my home are more suitable for these plants as well. Bathrooms are normally one of the more humid areas of your home, making them ideal for Chinese money plants. Whenever someone has a shower or bath, it generates steam and heat that can benefit your plant.

Whilst not essential, you can also use devices like thermometers or hygrometers (via Amazon) to ensure that you’re providing the right temperature and humidity ranges for your plants. This will help you keep track of temperature and humidity levels and allow you to adjust to seasonal changes.

Spring & Summer Care Tips

It’s essential to keep a close eye on the humidity of your plant during the spring and summer. The hotter summer temperatures should be monitored carefully to ensure they don’t get too hot for your Pilea peperomioides. Anything over 85ºF (30ºC) will be too hot for your plant, which lead to foliage wilting and drooping.

Depending on your local climate, you may experience humid summers. However, for those in a more arid climate, it’ll be harder to provide high humidity for your plant. If you aren’t using a humidifier, you’ll have to mist more frequently or keep pebble trays topped up with water.

Winter Care Tips

The colder, drier winter conditions can be problematic for Pilea plants. Drafts may also become more of a problem if you have open-air vents or active radiators near your plant. Thankfully, you can take some steps to keep your plant warm and humid during the winter.

The temperature inside your home will probably still be high enough during the winter. Make sure to use a humidifier to maintain the proper humidity levels.

Pilea Temperature and Humidity Tolerances FAQs:

What temperature is too cold for Pilea peperomioides?

Temperatures that are below 50 to 55ºF (10 to 13ºC) are too cold for Pilea plants. Chinese money plants need warm, stable temperatures ranging from 60 to 85ºF (15 to 30ºC).

What temperature is too hot for Pilea peperomioides?

If the temperature rises above 85ºF (30ºC), it will be too hot for these plants. Although they like warm temperatures, excessive heat can cause problems like depressions in the foliage.

Are Pilea peperomioides heat-sensitive?

Pilea peperomioides plants can be sensitive to extreme temperature fluctuations. These houseplants require stable temperatures between 60 and 85ºF (15 to 30ºC). Drafts from windows, vents, or radiators are the most frequent cause of fluctuating temperatures.

Can I leave my Pilea peperomioides outside?

These plants can be left outside in warm climates during spring and summer. They are not hardy to outdoor winter temperatures that drop below 32ºF (0ºC).

How do I know if my Pilea peperomioides is healthy?

A healthy Pilea plant will have vibrant green leaves with no brown spots or depressions on the foliage. The leaves should not be curling, which can indicate temperature stress. Healthy plants will produce plenty of pups – which are essentially baby plants.

Wrapping Up

Pilea peperomioides plants are extremely popular thanks to their lovely leaves and easy care requirements. Providing the right temperature and humidity levels can really help your plants to thrive. Where possible, aim for temperatures ranging from 60 to 85ºF (15 to 30ºC) and humidity levels ranging from 50 to 75%.
