Gardening tool Romeo's put in cloth for drying (6)
I believe the answer is:
trowel
'gardening tool' is the definition.
(I know that trowel is a type of gardening tool)
'romeo's put in cloth for drying' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'put in' is an insertion indicator.
'cloth for drying' becomes 'towel' (I've seen this before).
'r' inserted inside 'towel' is 'TROWEL'.
(Other definitions for trowel that I've seen before include "small digger" , "Gardener's scoop" , "Small gardening tool for lifting plants" , "Garden implement" , "Gardening implement" .)
