Hi all
Not my usual area of questioning but my wife (she does most of the gardening) noticed a funny whiteish-yellow substance on the underside of leaves and on the stem of a small variegated leafed shrub we have,
We've done the usual internet research but haven't been able to work it out. It even has my mum stumped and she has decades of gardening experience. We think we've ruled out mildew because it has a very subtle grainy texture, not flour like which is apparently how mildew manifests itself. We also can't see any moving bugs or creepy crawlies of any sort.
In most cases it's spread in a fine coat over the backs of the leaves and is yellower in colour - I though it might be eggs but I don't think so. In other places it's in whiter fluffier clumps.
Any help would be gratefully received.
