Worked in the garden dressed like a widow? (6)
I believe the answer is:
weeded
'worked in the garden' is the definition.
(weeding is a gardening activity)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for weeded that I've seen before include "Cleared of uncultivated plants" , "Removed unwanted growth from garden" , "Removed unwanted wild plants from garden" , "Removed unwanted or wild growths from garden" , "Took out garden invaders" .)
