Like a neglected garden (5)
I believe the answer is:
weedy
'like a neglected garden' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for weedy that I've seen before include "Scraggy" , "wimpish" , "Skinny" , "like an untended flower bed?" , "Underdeveloped" .)
