WHICH TYPES OF HOLIDAY CACTUS DO YOU HAVE?
"There are many different types of cacti that bloom between Thanksgiving and Easter. Each is appropriately named by the holiday it blooms near. The differences between these plants are found in the leaf edges. Christmas cacti have scalloped edges while Thanksgiving and Easter cacti have pointed edges. The Thanksgiving cactus is most common, probably because it is easier to get to bloom. They each are available in a variety of flower colors including white, pink, red, and orange.
When purchasing a new plant, look for uniform green growth, and good flower bud set. While "cacti" usually suggest high temperatures and dry air, this is not what these holiday bloomers prefer. Unlike most cacti, these like moist soil and cooler temperatures.
Take care of your flowering cacti much like you would any other houseplant. Give it a cool, sunny window or other location with bright, indirect light. Too much light can cause flower color to fade. Day temperatures of 70o F and evening temperatures of 60-65oF are considered ideal. Avoid overwatering during flowering. Do not fertilize when plants are flowering."
