It can be grown with love in a cracked basin (6)
I believe the answer is:
bonsai
'it can be grown' is the definition.
The definition suggests a singular noun which matches the answer.
'love in a cracked basin' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'in' is an insertion indicator.
'a cracked' indicates anagramming the letters.
'basin' with letters rearranged gives 'bnsai'.
'o' going within 'bnsai' is 'BONSAI'.
'with' is the link.
Can you help me to learn more?
(Other definitions for bonsai that I've seen before include "Small tree" , "Japanese art of growing dwarf trees" , "Japanese art of growing miniature trees" , "The art of growing ornamental dwarfed plants" , "Little Japanese growth" .)
