'forrest loam' potting soil & a bit of ground chalk
Well I re-potted about 1/2 of my crowded seedlings today (actualy I think some are 1 1/2 years or older but where planted several to a pot and showing a big differance in growth rate for seedlings in the same pot. So they now each have there own pot. I went to the edge of our lot and got "forrest loam" mixed in a little ground up chalk and mixed in the soil from the pots the seedlings have been growing in. The 'soil" seems to be draining well now I just have to see if it also retains moisture. I'm planning on using a simaler mix, minus the chalk, later for my Trilliums after they die back for summer. I'll let you know how my "soil" mix works out for the Hellebores.
Take care, Penny
