see attached photograph of my 7 month old rhododendron in a pot, with red spots which appeared on 8 of its leaves two weeks ago. I am frightened it might be "phytothera" - I have removed the leaves & destroyed them. All this happened two weeks ago. I dont want to lose this otherwise healthy plant, it gave us a wonderful floral display for a month, Is budding up well for next season, & looks otherwise very healthy, lovely dark green leaves.
i need advice please on what I can do to save it ? I am watching it carefully. Can anyone help ?
thankyou. ???? Tads
