Knautia macedonica

28 July 2009 07:24:54

I see the plant of the day is Knautia macedonica. Three of my plants have been blighted this year by powdery mildew and I was wondering if I should just get rid of them. Two others are blooming away quite happily, unscathed, although they are not planted in the same place.

I presume that the term 'powdery mildew' refers to the effect rather than the cause but will the fungus - whichever one it is - affect other plants if I pop them in the same spot. (I'm not convinced any of this makes sense.)

What I want to know is whether the fungus attacking the Knautia is likely to attack other plants. Hmmmmmmmmmm - when I think of it there are perfectly healthy 'other plants' around the Knautia.

OK - start again. Are my Knautia doomed? Is it just the year that's in it? Is the fungus here to stay? Will I bin the Knautia or should they be given a reprieve? Can it be dealt with and if so how? 

And there's a medal for anyone who has persevered so far.

Checking out digital cameras on the web these days. Fed up of having to rely on friends and missing the moment.

Have been reading up of Powdery Mildew as it is driving me mad on my Japanese Honeysuckle. I found this article suggesting good results with spraying once a week with 1oz of Bread Soda in a gallon of water. Should start at beginning of growing season, but I am going to give it a go.

Thanks for that Monkells. There might just be a stay of execution. I hope it works on the honeysuckle for you. It would be a pity to lose it.
