Newer cultivators have larger leaves then older varieties.

Crown of Thorns are susceptible to fungus issues. You can use a fungicide on the plants.
Bacterial leaf spot can also be found on these plants. The disease is characterized by circular gray to brown leaf
spots surrounded by distinct yellow halos. The infected leaves often turn
yellow and fall off the plants. Leafs should be removed from the plant and disposed of. Make sure the plants have adequate air circulation.
Avoid getting water on the leaves and stems.
