A nuisance when one's hoeing? (8)
I believe the answer is:
bindweed
'one's hoeing?' is the definition.
I can't judge whether this definition defines the answer.
'a nuisance when' is the wordplay.
'a nuisance' becomes 'bind' (I've seen this before).
'when' becomes 'weed' (I am not sure about this - if you are sure you should believe this answer much more).
'bind'+'weed'='BINDWEED'
Can you help me to learn more?
(Other definitions for bindweed that I've seen before include "Convolvulus" , "Gardener's bane - widen bed (anag)" , "Twining invasive plant" , "Be winded (anag.)" , "Strangler" .)
