A plant can withstand temperatures of roughly 28 to 32 degrees Fahrenheit without suffering too much harm.

Some plant species can survive temperatures as low as 33 degrees Fahrenheit, whereas others can only survive temperatures over 35 degrees Fahrenheit.

It all depends on the innate capacity of each plant to withstand particular temperatures.

In this article, we will discuss which temperatures are too cold for plants.

How Cold Is Too Cold For Plants?

Many of the plants grown in the United States originated in tropical or semi-tropical conditions, such as the desert regions of Arizona and California.

The problem is that most of these plants cannot endure low temperatures, especially if they were cultivated in damp soil. Many of these plants are readily killed by a drop in temperature if they are exposed.

It’s also worth noting that various kinds of the same plant category can have modest differences in their ability to withstand cold without suffering frost damage. Below are some examples of houseplants from different categories.

1. Blooming Household plant is colorful and exotic plants include begonias, tillandsias, bromeliads, and more. It’s better to cultivate them at room temperature.

In the summer, they enjoy temperatures between 65 and 75 degrees Fahrenheit. In the winter, the temperature drops to 60 degrees Fahrenheit.

Because most of these plants are sensitive to temperatures outside of this range, make sure to put your tropical plant collection into an indoor environment, as they aren’t as hardy as houseplants with thick bark.

2. In some aspects, succulents resemble cactus, and they are desert plants. They can live in extremely hot weather during the day and freezing temperatures at night.

Although most of these plants cannot survive temperatures below 40 degrees Fahrenheit, they make excellent indoor plants.

3. Although ferns are tropical plants, they thrive in colder environments. The temperature should be between 60 and 65 degrees Fahrenheit at night, and approximately 70 degrees Fahrenheit during the day.

Three Signs Your Plants Are Too Cold

When temperatures are too low for a plant, it may shiver. In case of too much heat, it will engage its cores in a heat-saving process. In the case of freezing water, it ruptures its cells.

Once the temperature outside freezes its wet tissues at night, the plant cell will defrost, destroying the leaves and stems once the sun comes up. Three types of symptoms that plants might have trouble keeping their cool include:

  • 1. Droopy Or Curled-Up Leaves
  • 2. Rotting Stems
  • 3. Discoloration Of Leaves


Is it necessary to cover the plants tonight?

When there are subzero temperatures, cover your plants at night to protect them from getting damaged by cold temperatures.

When the temperature rises over 32 degrees Fahrenheit, make sure you move them, as this may lead to dehydration. Bring your outdoor plants indoors during winter so that they do not get damaged.

Moreover, always make sure that the soil holds enough moisture for the plant to have access to it at all times.

Are 50 degrees too cold for plants outside?

When the weather dips to 45-50 degrees, experts recommend taking your houseplants inside. It can be easier in general if you do it before the outdoor temps start to drop.
