Picked up gardening tools and sprinkler (4)
I believe the answer is:
hose
'sprinkler' is the definition.
(a hose can be used to sprinkle water)
'picked up gardening tools' is the wordplay.
'picked up' indicates a 'sounds like' (homophone) clue.
'gardening tools' becomes 'hoes' (I've seen this before).
'hoes' sounds like 'HOSE'.
'and' is the link.
(Other definitions for hose that I've seen before include "plumbing connection" , "footwear" , "Flexible pipe for liquid" , "Breeches (worn with a doublet)" , "Stockings, etc." .)
