Borage Bother


The Borage on our plot has been a Rookie success so far, but this week we noticed a spot of Borage bother.  While the characteristically brilliant blue flowers are in bloom, the leaves of the plant have gone a decidedly unhealthy looking dusty white.  A bit of research has shown that this is likely to be ‘powdery mildew’ which often strikes Borage grown in shady and damp conditions (as ours is).

The question is – what’s the best way to treat this unwelcome visitor ?  Google suggests a drink of milk, a compost tea or even a sprinkle of fresh urine might do the job !  With Mr O poised at the flower border ready to do his duty, do you know of a better treatment for powdery mildew ?  Answers (gratefully received) on a postcard please !

    Any chance you could find a sunny spot for it? They are tough plants and wouldn’t mind a move! Milk and water spray is supposed to be very good! Xx

    1. I think we’ll move it, there are plenty of sunny spots on the plot ! Fingers crossed we don’t lose it as it’s so lovely 🙂

        Dig deeply and make sure you have a nice big ball of soil with the roots and it will never know! Xxx

  2. Had the same problem and last week had to dig up the borage which I had planted in a very shady area. If you have any success with getting rid of the mildew please post on your blog.

    1. Will do. I think we’re going to try the milk and water spray, then dig it up and move it to a sunnier spot, so fingers crossed 🙂

    Borage has been a perennial pest on our allotment – it shows up right where it isn’t wanted! It definitely will thank you for as much sunlight as you can give it. Good luck!

    1. Thanks 🙂 – I fear the end may be nigh for our Borage, it looks worse than ever – definitely time for some definitive action !

    My borage is the same. I’ve moved some to the front of my house, the beds there are getting baked at the moment so hopefully the mildew won’t set in.
