Can anything be done to save my garrya
I inherited this garrya in an old pot. It sat in the garden for a time looking miserable ( I didn't know what it was) however last witer it actually fowered and lovely long tassles appeared, hence I was able to iddentify it. I have since put it into the back of a border sheltered but sunny spot. However it has not put on any growth and the leaves are spotted and yellowing ,It still does not appear to be very happy. I think it is an old shrub and there does appear to be a small stump where it was obviously heavily reduced at some point . I am wondering if there is any thing to be done for it or is it beyond help? If so what ?
