Forced to agree with dandelion being uprooted (6,4)
I believe the answer is:
nailed down
'forced to agree' is the definition.
(as in nailing someone down on some issue)
'with dandelion being uprooted' is the wordplay.
'with' becomes 'w' (abbreviation).
'being uprooted' indicates an anagram.
'w'+'dandelion'='wdandelion'
'wdandelion' with letters rearranged gives 'NAILED DOWN'.
(Other definitions for nailed down that I've seen before include "firm" , "definitely settled" .)
