My Heuchera Georgia Peach leaves have developed puckered spots on the top and on closer inspection under neath they seem to be covered with what looks like grey/white mealy bugs. Any ideas what they might be without a photo and how to treat them please. The flowers seem to be unaffected.

Look up heuchera rust (specific to heucheras). IF that's what it is then the remedy is to cut off all foliage, and let them start again, which they will, no problem. You may have to spray with a fungicide as the new leaves emerge. Very easily spread onto other heucheras, although heucherella and tiarella seem to be immune. I say, seem to be!
