(1) Here's what I found regarding blueberry pollination @:
http://www.noursefarms.com/planting_gui ... guide.html
"It is best to plant at least 2 blueberry varieties for good cross-pollination. Cross pollination leads to bigger berries and more of them.
Any combination of varieties will work."
(2) Here's what I found for "Greengage" - I'm not sure if the "Early" is that significant? - @:
http://www.keepers-nursery.co.uk/search ... ?id=EARGRE
"Early Greengage is self-
sterile and requires a pollinator to produce a crop."
(3) You said:
"I imagine apple trees that are double grafted will pollinate each other."
I agree, and assume someone at least did that homework... Here's what I found on the Cox @
http://www.keepers-nursery.co.uk/search ... P&pageno=9
Cox's Orange Pippin is listed as: Self-
sterile. Golden Delicious
is a pollinator for Cox's Orange Pippin, Granny Smith is not.
Keep us posted
