Fruit symptom at orchard centre (6)

I believe the answer is:

tomato

I'm a little stuck... Click here to teach me more about this clue!

'fruit' is the definition.
(type of fruit)

'symptom at orchard centre' is the wordplay.
'symptom' becomes 'tom' (I am not sure about this - if you are sure you should believe this answer much more).
'orchard' becomes 'grove' (synonyms).
'centre' indicates the central letters.
The central letter of 'grove' is 'o'.
'tom'+'at'+'o'='TOMATO'

Can you help me to learn more?

(Other definitions for tomato that I've seen before include "Type of sauce" , ""Plum" or "beef" fruit?" , "A motto turned out to be fruit/veg" , "A motto, strangely, for this fruit" , "Fruit-vegetable" .)

I've seen this clue in the Sydney Morning Herald.
