How to Use the Indoor Plant Temperature Calculator
The same room temperature can feel very different to your houseplants depending on the type — tropical plants prefer warmth while succulents tolerate cooler conditions, since each has adapted to its native climate. This calculator takes your plant type and current room temperature to show the ideal range and current status.
Succulents thrive at 59-77°F, tropical plants at 64-81°F, temperate foliage plants at 59-75°F, orchids at 64-75°F, and herbs at 59-75°F. Temperatures outside these ranges trigger a caution grade, and temperatures reaching truly harmful extremes trigger a danger grade. If you see a danger grade, move the plant away from windows or direct AC/heater airflow right away.
Frequently Asked Questions
Plants tolerate different temperature ranges based on their native climate — tropical plants prefer warmth, while succulents tolerate cooler conditions.
Move the plant away from windows or direct AC/heater airflow right away, and adjust the room to the ideal range.
This calculator judges based on the current temperature, so if swings are large, also check the overnight low separately.
