Please could I get some advice on my Heuchera Key Lime Pie as it looks really horrid? Two photos attached. Could the red dots be rust or could spider mite cause this? We have lots of red spider mite but it's never affected any of my plants before. I am keeping plant in the shade as recommended and of course it's had plenty of water!! It's in a pot. I cut off all of the leaves in spring because they looked like this and the new growth was very healthy but then all of a sudden the blotches and spots came back :-( Also, is this problem likely to affect cutting of Heuchera Obsidian that I am currently nurturing or it it linked to Key Lime Pie only? Poor thing is starting to flower but the leaves look so horrid I'm thinking of cutting them all off again! Cross fingers you can help me to restore this lovely plant!
