Does anyone know how to get rid of black spots on echinacea leaves?
Without a picture it is hard to say-but to my way of thinking they will be going over shortly then just cut hard back
Any spray now is unlikely to be effective
Thank you, I will do that. Yes they are going over now but I was wondering if the black spot would stay with the plant and ruin it for next year.
on the same subject of echinaceas & cutting them back. I've sowed some from seed this year and at the moment I have some flower heads developing. I know that as it October these flowers are not going to come into fruition. I was going to just let them die back naturally........is this the right thing to do?
I'm going to cut the echinacea's right down today, noticed that the flowers which were lovely have now gone black also. Will the black spot stay with the plant and will I need to spray next year before it starts growing properly and if so what with. I love the plant, the flowers just went on and on and then in their prime just died. I also have a lot of trouble with black spot on roses (sussex uk)
Tricia-it is unlikely to be the same disease as the black spot on the roses-but no harm will come to them if you do a preventative spray next year with a fungicide-a lot of it is weather related-in a better year you probably wouldn't get it
There have been a lot of reports of vegetable blight this year-it is just one of those things
Too much rain, too little rain, what to do. Thanks for great advice.
Hollie-Hock, I agree with Christopher2 about cutting the flower heads off. I did this with a couple of new echinaceas last year (even though it was very tempting to let the flowers grow), and they have performed amazingly this year - huge amounts of flowers. Well worth it.
