I have just treated all my Heucheras to vine weevil killer drench. I repeat this in spring.
Most Heucheras are attacked by vine weevils and need to be treated or they are lost.
Nematodes are a good organic alternative but these need to be used in mid spring and again no later than end of September.
Bob, lucky you. The yellows are so difficult for me but I,think its because light levels are pretty high down here. I keep trying and experimenting and getting some success at last.
