I have moved blackthorn shrubs, about 24 inches high, but they look dead. Moved them about 4 weeks ago.

They are likely suffering from shock associated with the move. Also, it is possible that there are air pockets in the soil that are affecting the roots. I would step firmly on the root balls to help collapse any air pockets. Flood the area with water to help fill them in. Up its watering as well. It may also have a fungus disease, so I would treat the plant with a fungicide.
