Does anyone have any methods with dealing with a serious attack of the bright bluey green monkshood aphid?
Just scanning the forum and came across your 'post' ; these are a serious aphid to deal with . It seems that agricultural chemicals (prohibitively expensive) would work , but accessing these may be difficult .
If my plants , at the expense of this years flowers , I would cut to ground and safely dispose of all foliage .
Then carefully (toxic roots) , separate and wash each stem and thoroughly sterilise with bleach . When dry , repot in containers and monitor their progress in the Spring . It might be a good idea to sterilise the soil they have been growing in also . Some might think it strange to talk about using bleach , but I have found that a strong solution is a very effective insecticide , as well as a germicide , viricide and killer of numerous bacteria . Cheaper too
Give it a go , what have you got to lose ?? Good luck !!
Many Thanks for your advice.
Will give it a go!
