Foremost of recommendations in report is support for growth (7)
I believe the answer is:
trellis
'support for growth' is the definition.
'trellis' can be an answer for 'support'. I'm not sure about the 'for growth' bit.
'foremost of recommendations in report is' is the wordplay.
'foremost of' suggests taking the first letters.
'in' is an insertion indicator.
'report' becomes 'tell' (to report is to tell someone about something).
The first letter of 'recommendations' is 'r'.
'r' put into 'tell' is 'trell'.
'trell'+'is'='TRELLIS'
Can you help me to learn more?
(Other definitions for trellis that I've seen before include "garden equipment" , "where climbers may be trained" , "trainer" , "latticework in the garden" , "Latticework for climbing plants" .)
