I'd like to naturalise crocuses in a lawn. Could anybody advise me how
many bulbs per square meter do I need?

My experience has always been "more than I can afford this year". Say,
a hundred per sq m, slightly grouped, if you want a strong effect from
the start. I say "slightly grouped" because they look more natural that
way, and because I like uneven groups of separate colours, overlapping
a bit. If you prefer a multi-coloured pointilliste effect, you'll
probably get mixed bulbs cheaper than as separate varieties; but I
wouldn't spread those too evenly, either.
