I tried to do grape vines before and the only thing that worked out was the grapes. I used Woodland Scenics oranges. Dipped a bit of wire in glue then rolled it around in the oranges and let it set. Might work for you.
Well I did something similar, just with small bearing balls.

I got these ages ago (maybe even before 2000) from my late uncle, but never could find a use for them.
I glued a small plastic bead to a piece of wire and built up the cluster one at a time using superglue.

After this I primed them and applied two coats of polyurethane varnish to really bond them together.
The copies turned out to be ok. Not as good as the originals, but they will work.

For the plants I used some leftover GW Dryad bits. They are pinned to the base.

Tomorrow I will texture the base an add the rest of the fruit.
I will glue on the leaves too (I have some laser cut leaves and a puncher from AK), then prime the whole thing. I'm not sure how this will work out. I may have to add the leaves after painting.
I plan to make six of these bases, probably three with fruit and three without, but I may add fruit to all of them.
Should be a good year, regardless.
Curious to see what you'll make of the building 
Well about that I have no idea yet. I need to do some research first.
It should be small though, no 40x40 cm footprint this time

I have less free time this year.
