A photograph or two showing both the plant and its container would be very useful, but in the meantime, suggest you turn it out of its pot anyway to see if there are any invaders in the compost, or whether the plant is rootbound. Also check the stems and backs of leaves for signs of infestation or disease.

Thankyou for your reply you were correct there was invaders in the roots so I am afraid it has gone to the big compost heap in the sky " better luck next time" Thanks.
