Growing Linanthus dichotomus

[lebuhn]

I have been struggling to easily grow Linanthus dichotomus from seed. I'm having some real issues with damping off and am considering resorting to some sort of fungicide and/or trying a cactus mix. I've been growing them in half soil, half sand. Does anyone have advice on what's worked with other desert to serpentine species?

Thanks,

Gretchen
