Lithodora

Just wondering if anyone else has found a way to grow clean Lithodora in pots? I know they like it dry but I still seem to get the dreaded Phoma blight on them causing them to go black and sickly.
Any thoughts?

 

I have two in the ground and one potted and the latter really doesn't like being confined so i'll let it free soon.

I can tell you that the soil they thrive in has to be as thin as possible - preferebaly all grit .... is yours given that type ?
Why do you keep yours potted ?

My two healthier ones are in thin, poor soil, neutral-alkaline, and sun for the latter half of the day.

 

Thanks Louise,

Sounds like they really seem to struggle in the pots. I grow them in pots for landscaping purposes, need em mobile!
I have seen plenty of crops of them grown in pots of peat growing very healthy and in full bloom. While mine and numerous other potted crops I have seen start ok, by the time they get ready for sale, they start going black and the phoma takes hold.

I believe they prefer an acid soil and this may be something I might have to try.
While I would love to use fine thin soil, I can't due to the need for mobility with the pots
