Taginfo is your friend to find out what tags are most commonly used.

It tells you on

https://taginfo.openstreetmap.org/tags/landuse=orchard#combinations

landuse=orchard + trees=*: 82k cases
landuse=orchard + crop=*: 4.9k cases
landuse=orchard + produce=*: 2.9 cases

and you can also see that genus=* and species=* are much more common 
than crop=* or produce=*.

If you look at:

https://taginfo.openstreetmap.org/keys/crop#values

You can see that this tag is most commonly used for farmland.

If you look down the list you can also spot 945 cases of 
crop=bananas,_papapyas,_mangos

https://taginfo.openstreetmap.org/tags/crop=bananas%2C_papapyas%2C_mangos

which - if you follow the link to overpass turbo - turn out to all be on 
an island in Nicaragua in combination with landuse=orchard.

Safe to say that trees=* is the dominating method to tag what is grown 
in an orchard.

Note the wiki is currently fairly unclear about the separation between 
landuse=orchard and landuse=farmland.  On 

https://wiki.openstreetmap.org/wiki/Tag%3Alanduse%3Dorchard

it suggests landuse=plantation for fruit bushes which links to 
landuse=plant_nursery which is clearly unsuited for this purpose.  This 
seriously needs clarification.
