In the garden, a bit of manipulation sets it back (5)
I believe the answer is:
lupin
'it back' is the definition.
The definition suggests a singular noun which matches the answer.
'in the garden a bit of manipulation sets' is the wordplay.
'LUPIN' is hidden backwards within the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for lupin that I've seen before include "Nil up in this flower" , "Flower called after wolf" , "Plant with flowers on long spikes" , "It has tall flower spike" , "Flowering plant" .)
