The hemerocallis will be fine to move Nariz, tough plants, I usually split mine september time, just cut the leaves back by about half when replanting.

Mulching, partial shade, and attentive watering all discourage bolting in lettuce, but aren't infallible. Cheer up! Your fall crop should have much less trouble!

Thanks guys! Glad I can move the Hemerocallis - I thought I'd planted them in the right place, but they got rather overshadowed by thuggy Sweet Williams! I plant lettuces between tomatoes which give partial shade - never thought of mulching them and they get watered when the rest of the garden does. Maybe I should be more selective? Note to self: Must do better! ;o)
