Tropical plants like hot , sticky weather while xeriscaping (drough-tolerant) plants thrive in high-temperature climates that see little rain fall. This will be devastating for the majority of houseplants. Temperature too high: Plant the right kind of heat -loving plants for your environment, be it dry or humid. Although they may rebound, the foliage is likely to be seriously damaged. Above 75°f (24°) is too high for most plants indoors, although outdoors they’re fine. The good news is that most common houseplants do well in temperatures that are pleasant for us, which is usually between 18°c and 24°c (65°f and 75°f). · what are the best temperature ranges for common houseplants , and why is this so important for their health? · temperature too high: · some plants grow well in higher temperatures which are usually placed in humidity trays and are misted regularly. Anything below 2. 2°c (36°f) can cause one. Some will cope with the cold of course, but others will suffer as soon as the temperature creeps below 10°c (50°f). For most indoor plants, temperatures exceeding 75°f (24°c) are unsuitable, while plants outdoors may tolerate higher heat. Temperature changes of around 20 degrees in a short period of time can stress a plant and overwhelm it, hancock says. · while indoor plants are relatively resilient when it comes to hot temperatures, they’re more likely to struggle if they’re exposed to heat in an unnatural way. Indoor conditions lack sufficient air humidity and sunlight, leading to intolerance of high temperatures. · above 104°f, many plants will survive but will show different signs of heat stress depending on plant type, maturity of the plant and factors that often come with high temperatures, such as drought or wind.
