Cultivation Notes:

Opuntia Erinacea grows best in soils with pH between 5.0 and 7.5 (Acid - Neutral). For adequate growth it requires porous cactus soil as well as efficient airflow. Regarding watering, apply water thoroughly when the soil is dry to the touch (1,2). Typically it is standard to propagate cacti during late spring in order to provide them plenty of time to be established before the winter months bring cold temperatures (3). Opuntia Erinacea can be propagated from pad cuttings or grown by seeds. Typically it is easier to propagate this catic through pad cuttings. In order to efficiently produce rooting you should wait 1 - 2 weeks to plant after making the cutting (2). Plant the cuttings roughly 1 inch deep into the ground. The roots will develop in about 1 month and should be watered when the top one inch of the soil feels dry to the touch ().
