Yes you are right Hcarlton, i didn't thought to the pollution. Maybe a neutral substrate is enough.
@FrankenSnyder, could work crushed egg shells instead of seashells?

Bone meal would be more funI have been growing Alpine D. anglica (var. pusilla) and my Super Sundew on neutral to slightly alkaline gravel including decomposed granite. Looks good topped with live sphagnum. More info:
D. anglica Alpine x HI
I did a simple test: Poured a solution of crushed sea shells into a cup holding a small Super Sundew which was forming a weak flower stalk. After the phosphate dose there was a growth spurt and the flower opened perfectly with much pollen. I wish all you growing linearis good luck as it is a very interesting plant and fairly rare.
really thank you for the news! right few days ago i sowed some seeds (others sowed in classic mix with quartz sand and few peat) in pure fine quartz sand in which i mixed a little bit of crushed (powder) egg shell, let's see what happens with this mix. Thank you for your wishes!
