Can you prune a crown of thorns? Mine is sticking out all over and is unruly at times. It is quite a large plant. Thank you

Yes, you can prune a crown of thorns by removing up to 1/2 of the plant's total size at once. You can prune individual branches back, optimally to where a lateral branch emerges or where you see a bud so that the plant will regrow from that point. You can also remove whole braches if the plant is too dense. Wear gloves while pruning your crown of thorns, because it contains irritating, toxic sap.
