Houseplant Needs

Temperature

Most foliage plants prefer day temperatures between 65 degrees and 75 degrees with night temperatures usually 5 to 10 degrees lower. Avoid extreme temperature changes, such as cold and hot air blasts from windows, radiators, heating and air conditioning vents. Take special care near cold window panes too. Cold glass can damage foliage.
