Houseplant care: Move tropical plants indoors before the first frost

To protect tropical and subtropical plants from damage, they should be moved indoors before the first frost occurs. Experts recommend beginning preparations in late September, specifically when nighttime temperatures approach 10 degrees Celsius.

Sensitive species such as Ficus, Monstera, Dieffenbachia, Croton, Dracaena, palms, and Philodendron are particularly vulnerable to cold nights, even if daytime temperatures remain warm. Basil is also highly sensitive to cold. While cacti and succulents tolerate cooler weather better, they should not be left outside until the frost arrives.

To prevent root rot, it is advised to bring plants inside when the soil is relatively dry, as the combination of cold and excessive moisture can be harmful. For plants that can tolerate slightly lower temperatures, such as geraniums, rosemary, or bay laurel, they may remain outdoors longer but should still be moved before significant cooling or frost sets in.
