Tangy Green™ Urban™ Columnar Apple

I previously planted a dwarf Macintosh and an Everest crab apple two years ago and my Mac hasn't even flowered. They are about 40 ft. apart. Will a Tangy Green Columnar pollinate the Mac?

Yes, it will. This apple tree is in Bloom Group 3, and the Macintosh is in Bloom Group 2. 

Which of the columnar apples are resistant to cedar rust? Thanks in advance.

Columnar apples are derived from McIntosh apples, which means they all have some resistance to cedar-apple rust. Resistance does not mean immunity however and your experience may vary from others.

I see the Tangy Green is resistant to apple scab and powdery mildew but is it also resistant to fire blight?

Columnar apples are not bred to be specifically resisitant to fireblight, nor has there been extensive testing done on them.

Would the Tangy Green be comparable in flavor like a Granny Smith?

Yes, it is a tart sub-acid McIntosh.

The reply to another question says that these trees aren't disease resistant but the description specifically says they are highly disease resistant selections. Which is correct, the tree description or the answer to the question?

Tangy Green Urban Apple is extremely resistant to diseases like apple scab and powdery mildew, but it is not resistant to Cedar-Apple Rust. I hope that helps clarify things.

In general, what is the approximate yield of a columnar apple tree?

Approximately 1/8 bushel.

Will the Tangy Green Columnar apple be pollinated by either an Arkansas Black or a Liberty? Thanks. Oh, when do they ship?

By either yes and shipping for bareroot trees is spring of 2023, depending on your area.

is this tree, or any of your columnar apple trees resistant to Cedar Apple Scab?

Columnar apples are not bred for disease resistance. You want Liberty or Enterprise for that disease.
