I tend to agree with nutcutlet.
Any plant in a pot is dependant on us to feed it. Watering probably has been too excess this yr, through the awful weather. That means that any remaining nutrients in the pot compost will have long gone- either used up &/or washed out.
So any permanent pot planting needs at least an annual feeding- you can push in those pellets in early spring. If you havent repotted it since purchase, nor topped up the compost that wont have helped either.
I'd be inclined to repot it into fresh compost early this coming spring, or now if not actually freezing out there, using one designed for more permanent planting- ie JIno3 type. Then also remember to feed it occasionally & in the following spring, 014, replace the top couple of inches of pot compost with fresh. That way you dont need to repot it every yr. J.
