Moisten a few flowers? (5)
I believe the answer is:
spray
This could be a double definition.
'moisten' is the first definition.
(thesaurus)
'a few flowers?' is the second definition.
'spray' can be an answer for 'flowers?' (I've seen this before). I am not sure about the 'a few' bit.
Can you help me to learn more?
(Other definitions for spray that I've seen before include "Liquid from an aerosol" , "Bunch of flowers" , "Sprinkle water on - a small bouquet" , "Disperse in tiny drops" , "Drench" .)
