I have some lettuce plants growing happily in 6-cell packs,
also some bok choy and choy sum (another Chinese green in
the cabbage family). I've been putting these outdoors
whenever the sun is shining, so they're pretty well hardened
off.

They'll be planted in containers outdoors - so I don't have
to wait 'until the soil can be worked' (until the garden can
be tilled) to plant them. Our garden is heavy clay, and
very soggy in spring - it really can't be tilled until
mid-to-late May. (This is the major reason I'm working on
getting raised beds.)

The information I've seen on lettuce says 'plant outside
four weeks before last frost' ... which strikes me as rather
un adventuresome. For bok choy and the choy sum, I've no
information as to when they go outside.

When to plant the lettuce and Chinese greens outdoors,
relative to the last frost date? When do you plant them
out?

I can cover them at night if need be.
