Hello Fred, IMO ... a gritty, very well draining mix, with NO organic material, is best for these. My own mix is equal parts pumice, DG (Decomposed Granite Sand) and perlite, topped with large-particled DG to keep perlite and pumice from floating to the top. If no DG, gritty sand or very small pebbles (as for aquariums) should work. After germination and production of the first leaf, a very weak fertilizer solution with every other watering may be beneficial. I usually transplant to a mix including some organic material after the first or second year of growth. Seeds should not be covered but surrounded by larger particles to hold them in place during germination. I keep a plastic humidity dome over them until the formation of the first leaf. I find seedlings do OK the first year in some shade ... out of direct sunlight. BTW ... I am having very high germination rates with seeds of these same batches.

Amaryllis belladonna (light pink) X Brunsvigia littoralis 7. Amaryllis belladonna (large-flowered, medium pink) X Nerine angulata My question is, what is the best medium to start these seeds. I live in the Northeast where light is a bit of an issue, but I do have lighted plant carts ...
