Thanks so much for your help! The plant is in a pot and I'll try
re-potting it. Is there anything I can look for in the roots that
would give me an idea of the plants health?

I found the name of the plant, its Eugenia stipitata, it grows as a
bush in the Azores with waxy green leaves and produces a small hard
shelled fruit about the size of a lemon at its biggest. Until the
fruit reaches maturity it is green then turns yellow.
