I have two Granny Smith apple trees that both bloom profusely, planted about 3 or 4 years ago. One way smaller than the other one but that's the one that produces fruit. Majority of suggestions are than two different varieties need to be planted for cross pollination success, but do the large commercial orchards do this? Seems unlikely to me. Thank you. Fran
"Granny Smith" apple trees produce a better crop if cross-pollinated with a suitable apple tree variety.
To cross-pollinate apple tree varieties, you have to plant a compatible tree. "Snowdrift" crabapple is a useful pollenizer for apple trees that bloom mid- to late-season, like "Granny Smith." "Golden Delicious" is another smart choice because of its heavy pollen production. When choosing trees for cross-pollination, it is important that you choose apple varieties with overlapping bloom times because very early and very late varieties cannot pollinate each other.
I have a large apple tree that is full of green apples, some are starting to fall. They are a little tangy in taste. Are they ripe now? This is the end of May and first of June.

Wondering the reason why my granny smith would showing small amounts of blossom only a month away from harvest?
Stress is the short answer. Whether this be temperature fluctuation, improper soils conditions, insects, fungi, or other stressors, it is some some sort of stress.
If everything else looks fine, and no other symptoms are present, then it is not likely anything to cause concern.
Does Granny s.g.apple tree need another apple tree to pollinate and produce fruit?
They are self fertile, but will produce much more heavily with a pollinator of another type.
This tree is to be a pollinator for an established honeycrisp apple tree.
This should be planed right before leafing out in spring, or right after going dormant in fall.
