Greengages
 

Help Please

I have a very good crop of greengages coming along. One tree with lot of
billiard ball size fruits.
The problem is that if I leave them on the tree until they are fully ripe
the wasps will get them all.
Can I Pick them just before they are ripe,store them in a cool fridge an get
a few out to ripen as I want them

Thanks

Paul
