Succulents tend to prefer a temperate climate. Generally they do best in areas with filtered sunlight and temperatures below 90 degrees. Most succulents can tolerate full sunlight, however some can get sunburn if they are in full sun during the afternoon when the temperatures are highest (Aeonium are especially susceptible). Full sun in combination with temperatures above 90 can damage most succulents. Morning and/or evening sun with afternoon full or partial shade (at least 50%) is ideal.
Newly planted succulents, especially those that have been growing in a greenhouse, will need to be shaded for a few days and gradually introduced to more sunlight. This is also the case when bringing succulents that have been grown indoors outside.
