'that'll feed plants' is the definition.
The definition suggests a singular noun which matches the answer.

'around forest finally decomposing socks' is the wordplay.
'around' means one lot of letters goes inside another.
'forest' becomes 'arden' (Arden, forest in Shakespeare's As You Like It).
'finally' says to take the final letters.
'socks' becomes 'hose' (I've seen this before).
The last letter of 'decomposing' is 'g'.
'g'+'hose'='ghose'
'arden' inserted inside 'ghose' is 'GARDEN HOSE'.
