Vermiculite or grit for covering seeds?
I have been busy reading up on seed sowing techniques and opinion seems divided on whether to cover seeds with seived compost, perlite, fine vermiculite or horticultural grit. I have found some alternatives. One is called "chick grit" which is very fine and looks more seed friendly and the other is crushed oyster shells. Both are actually intended for pigeons, cage birds or young poultry but look ideal for covering seeds. I would be very interested in what others do and why.
