Heuchera 'Lime Marmalade' help!
Just looking for some advice on some Heuchera Lime Marmalades I've planted in my garden along the border.
I planted them last August and they looked great until a couple of months ago. Of the 7 all but two have flowered and now look pretty sad for themselves. The border is against a 2 metre fence and is easterly facing. Lot of sun until about 3pm, then shaded. The pics I've included show how close the healthy one is to the withered one. I thought these were hardy plants. Soil is moist and slightly clay based.
Any help much appreciated as they look great in the garden and I don't really want to lose them.
Thanks in advance for any help.
