Alternative to a watering can (4)
I believe the answer is:
hose
'alternative to a watering can' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hose that I've seen before include "Flexible tube for liquid" , "Piping" , "Breeches (worn with a doublet)" , "Garden implement" , "Socks and stockings" .)
