I see between the rains that it’s getting down into the 30s tonight. Since everything is wet, that can be a damaging cold, even if it’s not below freezing. Bring in all the Madagascar plants – Adeniums and Pachypodiums. Frost blankets over all the frost-sensitive plants like Kalanchoes and Aeoniums.
Any other plants you’re not sure of? Let us know what you have, in the comments, and where you are.
