RE: Chlorosis in Helleborus?

Eva,
My book on Hellebores - The Gardener's Guide to Growing Hellebores by Graham
Rice & Elizabeth Strangman says Hellebores like a soil pH of about 7.  That
is neutral, not "quite alkaline".  If I were you, I would get my soil tested
to see where your pH actually is.  It may be way too alkaline for them.  You
don't say what exposure you have - sun or shade?  Is there any organic
matter in the soil?  You might want to sacrifice a few seedlings to dig them
up and take a close look at the roots.  All the stuff you have poured on
them is good, but only if the roots can take it up.

The new growth on my Helleborus seedlings is very yellowish. Our soil west
of Chicago is quite alkaline, but hellebores are supposed to like that. Our
water is probably also alkaline. I have tried feeding the seedlings
acidifying fertilizer, micronutrients, ironite, magnesium but have not
noticed any difference. I never had this problem in Ohio. My seedlings there
were a healthy dark green. What should I do?
