The cultural
information should be used as a guide only, I have found a number
of different sowing techniques for the same seed from different
sources there does not seem to be a standard. With this in mind
you should use this website as a guide only, you probably already
have a tried and tested way of sowing different seeds. As a rule
of thumb the larger the seed size the more cover it requires, and
fine seed like Lobelia Begonia etc requires no cover.
