Temperatures for Cacti and Succulents

Most succulents are tolerant of very high temperatures and FULL sunshine, but ONLY if there is plenty of air circulation e.g. an open window or door. Without air, a sunny room can be like an oven on a hot day and your plants can cook.

In the winter, most plants are happy if kept at above 40 deg.F (5 deg.C) if dry.

Many such as Rebutia, Lobivia, Opuntia, Agave etc; will stand many degrees of frost if dry.

There are a few exceptions of course, most epiphytes such as Orchid and Christmas cacti are happier at around 50 deg. F (10 deg. C )
