As a gardening and landscaping expert, I have had personal experiences with croton plants and can provide you with a detailed answer to your question about the temperature that is too cold for crotons.
Croton plants originate from tropical climates, where they thrive in warm conditions. Therefore, they are not well-suited for cold temperatures. If the temperature drops too far below 55°F (12.8°C), croton plants may start to suffer damage, and their leaves can turn brown. This is a clear indication that the plant is not happy with the cold environment.
Ideally, croton plants prefer temperatures of 80°F (26.7°C) or below. They do not thrive in extreme heat either, so it’s important to find a balance. In my experience, crotons tend to do best when the temperature is around 70-80°F (21-27°C). This range provides the warmth they need without subjecting them to excessive heat.
It’s worth noting that crotons are sensitive to cold drafts as well. Even if the overall temperature in a room is within the acceptable range, if the plant is exposed to a cold draft, it can still suffer damage. This is something to keep in mind when placing your croton plant indoors, especially during winter months when windows and doors may be opened frequently.
In colder climates or during winter months, it is advisable to bring croton plants indoors or provide them with additional protection. If you choose to keep your croton outdoors in a colder climate, consider using a frost cloth or other protective covering during freezing temperatures.
To summarize the optimal temperature range for croton plants, it is best to keep them in an environment where the temperature is between 70-80°F (21-27°C). Temperatures below 55°F (12.8°C) can cause damage to the leaves, while extreme heat should also be avoided. By maintaining these temperature conditions, you can ensure that your croton plant thrives and remains healthy.
