Apple Pollination Chart

Here is an Apple Pollination Chart I've been working on that organizes varieties based on flower group / flowering time instead of alphabetically since that is the main driver for compatibility.

It also identifies triploid varieties that have sterile pollen and do not pollinate any other varieties.

Let me know what you think and if there are any mistakes or additions you'd like to see.

This is incredible, I really like it.

Keep up the good work.

That looks great! My only feedback is grammatical. You use the word "pollinator" where I think you really mean "pollenizer" or "pollinizer" (both spellings OK). The pollinator is the thing that carries the pollen from one flower to another (such as a honeybee), but the tree that the pollen came from is a "pollenizer."

Some references:

The most common error is found in fruit tree catalogs. For example, you will see one plum tree labeled as a "pollinator" for another variety of plum. Not possible. The BEE is the pollinator. The tree that provides fertile pollen for another tree is the "pollinizer".

All apple cultivars require cross-pollination with a pollinizer (not to be confused with a pollinator, which is a bee) to ensure commercial-quality fruit and yields.
