Hi I have some Euonymus plant (green and white) in my window box but it seems to always develope a white powdery substance on its leaves - bit like I'd shaken talc over the plant. It does not seem to be damanging the plant but does not look very nice - is there anything I can do about this. It has happened before the plants I had in the same window box.
Also my holly in a pot is dying any suggestions - I don't have access to ground just pots and containers.
