You know who will know this one are the folks at Pipers Orchard .. it's an apple orchard here in town ... located in Carkeek Park ... and under normal circumstances, sponsors an annual Festival of Fruit ... which features mainly apples (FWIW this is a totally fun event for kids).
Anyways, they have a map of which types of apple trees they grow, and information on "Gardening Guidance" .. specifically "Guild Planting", which is either what you're looking for, or closely related to it.
The fruit festival has a honeybee expert, who gives a presentation at the FF (I forget his name) ... you could ask for a referral to him ... he'll definitely know (he keeps his own bees and is highly knowledgeable in this area).
I have two different apple trees and they cross pollinate although I am not sure about your specific varieties. A tip though: When they blossom I help the process along by dusting my fingers on one and spreading the pollen to the other. It has also taken a few years for them to start regularly producing.
That’s great. Honey bees and bumbles typically won’t pollinate trees. Mason and American bees will. Masons are usually spring bees. So most are already moving back into hibernation. Remember to give them both a water and mud source.
They do pollinate each other. Some growers recommending planting a Crab Apple tree in between apple trees as bees love them and it helps pollination all around. Here's a cool link that you can check for all sorts of information on fruit trees orangepippintrees.com/polli...
