Why is my rose plant dying and how can I save it?

Your rose plant may be dying due to factors such as inadequate sunlight, improper watering, pests, or diseases. To save it, ensure it receives at least 6 hours of sunlight daily, water it deeply but infrequently, inspect for pests and treat accordingly, and prune any diseased parts. Additionally, consider fertilizing and providing proper air circulation to promote growth and health.
