Good players who make bloomers? (5)
I believe the answer is:
seeds
'good players' is the definition.
'seeds' can be an answer for 'players' (seed is a kind of player). I'm not sure about the 'good' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for seeds that I've seen before include "Initiates the growth of" , "Pips" , "nuts" , "Small hard fruits" , "More than one good player" .)
